On this episode of In Wheel Time Car Talk, we look at piston technology and how it has evolved over the years, from compression ratios in the 50s and 60s to modern ratios as high as 18 to one. We look at the flat top piston, the hemi piston, the wedge engine, and the notched piston. We learn about the innovative gasoline direct injected engines that use a powerball of air and fuel to push the piston down.
We also look into the incredible advancements in engine and vehicle safety, such as Honda's radical racing motorcycle engine with an oval-shaped piston that was later outlawed in competition. In our look at how compression ratios have changed over the years, we look at the development of air pumps, catalytic converters, and oxygen sensors that were developed to reduce emissions.
We also talk briefly about the Tesla agreement with Ford to provide access to the Tesla Supercharger network, which should encourage more EV development and acceptance by consumers.

Welcome to another in wheel time podcast, a 30-minute
mini version of the in wheeltime car show that airs live
every Saturday morning 8 to 11am, central Live.
it's the in wheel time car talkshow on our Saturday morning
live edition 8 to 11.
This is the last half hour.
Welcome to it, ladies andgentlemen coming up, conrad's
(00:22):
gonna have a special edition thein wheel time car clinic get
you Edgimicated on what's goingon and the internals of engines
you would.
Speaker 3 (00:33):
You would ask about piston rings.
I did that last week, so thisweek we're gonna talk pistons.
Good, i like that.
Speaker 1 (00:39):
We'll also give you a couple of auto news stories in
this half hour.
We think you'll enjoy it.
We invite you to stay tuned.
Howdy, along with Mike out ofthis world, mars King, conrad
DeLong.
We always need more.
Jeff Seekin, i'm Don Armstrong.
Thanks for joining us.
It's gonna be a beautifulweekend, holiday stuff, jeff's
birthday spanking.
Speaker 3 (01:02):
Spanking, so you can get that on the subscription
side.
Speaker 1 (01:07):
Behind the scenes make sure to say $10,000 to my
secret account and wherever soevery week we have Conrad do a
thing called the in wheel timecar clinic.
Gives you a little bit moredetailed information about
certain things about cars fromthe rear end.
Speaking of rear ends, Hey, heyhey, all the way up to the front
(01:29):
bumper.
And so I, conrad and I weretalking a couple of weeks ago
And I said why don't we get morespecific about certain engine
things?
and I brought up piston ringsand I thought that piston ring
thing was Very interesting.
I ran across the story aboutthe new evolution of piston
rings and Material makeup ofthem, the size of them, the, the
(01:52):
tension stuff, all of the stuffabout what they do And what
they do.
And it's not just one ring.
Speaker 3 (01:58):
But this week we're going to talk about pistons and
there are all sorts of differenttypes of pistons Depending on
the usage right, you know, ifyou kind of go back um into the
50s and 60s, compression ratioswere, you know, eight, nine to
one In the later 60s might havegot up to 10 or 11 to one, um,
(02:20):
and then, uh, you know, and thenwe've moved on up into the new
cars where you might see as highas 18 to one compression.
Well, one of the first pistonsthat were out there used was
what there was called the flattop piston.
There's, there's nothing on topof this piston is basically
flat and in some instances Theremay be some valve reliefs in
the piston and that's just togive a little bit of clearance
(02:41):
for The valves as they open andclose and they'll cut these
little notches in the valve inthe top of the piston for that
Valve relief.
This is very common lookingpiston out there In the industry
was a very common lookingpiston in the industry.
And uh, and then you, you knowwhat year, what year was that?
what year?
probably 60s, mid, mid 60s, yeah, and then you know, and then
(03:04):
the hemi and the hemi, thehemispherical combustion chamber
changed at all You know we'vegot valves that are on both
sides of massive ones, massive,huge valves, and in this case I
imagine this is probably a topfuel because there's you know
it's so highly domed Um and thatit's really a high compression
and pretty big reliefs cut inthe piston.
Speaker 2 (03:24):
When I see in that country the valves, multiple
slots for multiple rings Forcompression for three
compression rings and one oilring on it.
Speaker 3 (03:34):
So that's the hemi.
The next one would be the wedgeengine.
So you always heard the wedgeengine, uh, as the mo, par 440s,
maybe even the chevrolet bigblocks.
So there would be basically awedge on top of the piston with
valve reliefs cut into it againthat that Lift off of the base
of the piston is all aboutincreasing the compression ratio
(03:55):
, filling up the combustionchamber with metal To raise the
compression ratio on the engine.
So you're filling up the volumewith something with metal, yeah
right, and then and then again,the uh, um, the the notched, or
the uh the notched piston wasprobably the most popular over
time.
Well, now they've moved to umgasoline direct injected engines
(04:20):
.
And the gasoline directinjected engine, the piston has
a different function, where whatthey want is the fuel injector
sprays into that, what I'll callthe bathtub, right there in the
center of that, in the centerof that piston, and what it's
trying to do when the injectionsprays into there, it's trying
to bounce it all back up into.
(04:40):
Now.
I'm a star Uh trek fan, not astar wars fan.
So in star trek, you know, theyshoot the photon torpedo.
Little ball of energy.
So in this, in the gdi engine,they're trying to create a
little ball of air fuel mixtureright there at the spark, right
there at the tip of the sparkplug, which is a wonderful way
(05:00):
to do it.
The the issue with it is itmeans all of that outside area
gets very hot because it runsvery, very lean And in that.
So if you looked at how theinjector sprays on top of the
piston on a gdi engine, you'llsee that the injector sprays
into the middle of the pistonand it brings that whole air
fuel ratio Powerball right tothe tip of the spark plug.
(05:22):
So when the spark plug ignitesIt's got the proper air fuel
ratio, basically to create anexplosion that pushes the piston
down.
Speaker 2 (05:29):
So the, the, the pistons coming up with the
reservoir of fuel is what it'sdoing into that injector.
Speaker 3 (05:34):
Well, now it's coming up with a reservoir of air,
okay, and then the injectorsprays at a very high pressure
and really highly atomized rightthere at the top of the stroke.
Speaker 1 (05:43):
Yeah, right there at the top of the stroke and that
that puts the.
Speaker 3 (05:46):
Now this is a port fuel injection system.
So you can see there theinjector is behind the valve so
it sprays in on top of the valveAnd then it kind of fills the
combustion chamber.
That was a big thing in the 80s, right?
Yeah, port fuel was primarilyintroduced in the early 80s and
then there was the directinjected engine and my fault.
(06:08):
The yellow injector would dropdown underneath the valve and
the direct injected engine Wouldspray directly into the
combustion chambers.
That's why the compressionratio Being so high and the fuel
pressure is being so high, tobring that all in, and and the
technology is now that that WhatI call the bathtub is all
(06:28):
designed to reflect the fuelspray all up to the tip of the
spark plug, so they could useless fuel Still, get the correct
amount of air fuel mixture atthe tip of the spark plug To
push the piston down, and that'swhere the fuel economy benefits
come from the same burn powerwith less fuel with less fuel.
But the the you know, for everyaction there's an opposite and
(06:52):
opposite reaction.
The opposite reaction is thearea outside of where that fuel
is is very lean, and whencombustion temp, combustion goes
lean, it goes hot.
So you got to remember allaround that outside of that
piston is where the ringlandsare.
So that's where the problemcomes, with carbon deposits in
the ringlands and ring stickingand and Blow by.
(07:13):
And you know, with blow by youget gasoline in your oil, which
makes your oil more vaporous.
So it it evaporates faster aswell as gets sucked up through
the PCV system.
Speaker 4 (07:24):
So why not make the pistons smaller so you don't
have to deal with that heat onthe outside, because you still
have the same burn and you still, but you lose power.
Speaker 3 (07:35):
Right, you don't have enough surface, right well, and
one of the other big thingsthey did in the technology of
pistons is they have changed thelength of the skirt On a piston
.
So the skirt on a piston iswhat kept the piston from
rocking back and forth.
So in In one of those picturesand I forgot to get to it It
showed that they've actually puta Polymer pad on the side of
(07:59):
the piston to kind of fill inthat space, because a piston
skirt, when the piston gets hot,grows and and gets larger so
that the piston fits thecylinder better.
Well, there's a.
You know, a lot of engines havewhat's called a piston slap
when they're cold.
So this, this polymer pad, isdesigned to deal with that
piston slap, so that there's nowobble.
(08:20):
There's no wobble, you know,and it's kind of like Don and
Jeff.
They have short skirts as well.
Speaker 1 (08:26):
I have to tell you that my dad worked for a company
called walk a Shaw MotorCompany, and They developed
industrial engines all sorts ofsizes, from a little small four
cylinder that actually wasdeveloped to start Great, big,
huge, 12 and 16 cylinder enginesthat wouldn't even fit in this
(08:47):
room They're so big and heworked in the laboratory and in
the laboratory.
They did all of the testing andfound out you know, the best
way to fuel of them.
Many of them were Gasolinedriven, most of them were
diesels, some of them were gasnatural gas driven engines.
And He was in this laboratorywhere they actually blew up
(09:11):
engines and then they looked atthe damage and what caused it to
blow up.
Was it the RPM?
what couldn't handle the RPM?
The most efficient way to getinjection into Right all of that
and all of those were prettymuch injected engines back in
the day And I think that theystill are, that that company has
(09:33):
changed hands and dresserbought them and moved the
factory up I think up to Canada,but at any rate he worked in
the laboratory and that's whatthey did.
Speaker 3 (09:40):
And I'm sure your dad would would enjoy that piece,
because I'm sure he saw most ofthis evolve in his hands as The
design of engines changed overtime.
So pistons around.
Speaker 2 (09:53):
We get that not all.
I was gonna say They aren'tthere, some that are oval Yeah.
Speaker 3 (09:57):
Honda.
Honda made a racing motorcyclewith an oval shaped right.
Speaker 4 (10:03):
It was a v4 engine and a kidney bean shape It ended
up being outlawed because itwas just too.
Speaker 3 (10:10):
Radical yeah to advance for everything.
Speaker 1 (10:12):
Why would you do that ?
save space.
Speaker 3 (10:14):
Well, to save space.
But also you know you talkedabout the surface area, right Is
what creates the power.
So it gave them an opportunityto make more surface area on the
piston in a smaller Gotchacombustion area compartment,
right, yeah, because it's allabout size Of the engine as well
as size of what you're doinginside the engine.
Speaker 4 (10:35):
So let me ask you this so back, you know, 69, 70,
71, you know we were trying to,we were putting flat tops in, we
were trying to get compressionratios up 11, 12 to 1 or
something like that.
But then when the smog worldcame in, everything dropped to
like eight right and a half orsome so And now it's kind of
cycle where it's coming back up.
What, yeah?
(10:55):
Why?
why did that?
why did they do?
Speaker 3 (10:58):
that if?
Speaker 4 (10:59):
it's more efficient at the higher compression ratios
.
Speaker 3 (11:01):
Well, it's more efficient because the fuel
delivery systems are moreefficient today.
Back then, when you were doingthat, you were doing a Holley or
a Quadrajet, maybe even aCarter if you were high tech.
Speaker 4 (11:14):
We had Holley's as far as we got.
Speaker 2 (11:16):
Whatever they could get out of the junkyard.
Speaker 3 (11:18):
A carburetor spray is not an efficient fuel delivery
system.
It may work correctly, butthey're not an efficient fuel
delivery system.
They had to lower thecompression ratio to make sure
more of it burned efficiently sothe catalytic converter could
clean it up.
Today they can get a good,clean burn because they're
(11:39):
spraying much less fuel in tocreate remember what I said a
little photon torpedo rightthere at the tip of the spark
plug That burns more efficiently, so they can raise the
compression ratio and not haveto worry about unburned fuel
passing through the exhaust,which is the exhaust emissions
that the federal government'sconcerned.
Speaker 4 (11:57):
I knew it had something to do with the smog I
mean, that's what everybody said, oh, it's a smog, Take the smog
stuff off but didn't reallyunderstand the reasoning.
Speaker 1 (12:06):
They don't even use that technology and air pumps
and stuff like that.
Speaker 3 (12:09):
That's what I was just about to say.
You got to remember, back inthose days you had an air pump.
You actually had a belt drivenpump on the front of the engine
that pumped oxygenated air intothe exhaust manifold, trying to
burn off that unburned fuel Ordilute it.
No, actually trying to burn it.
I'll try to light it up andburn it off in the exhaust
(12:30):
stream as it was headed for thecatalytic converter.
Even before catalyticconverters, that air pump was
part of it.
Air injection reaction is whatair stood for, because they were
just literally trying to keepthe burn happening to kind of
clean up, If you stop and thinkabout all of that, how far we've
come in such a really a shortperiod of time.
Speaker 1 (12:51):
Right, You know, some of my favorite car shows are
The Restores show And alsobelieve it or not, don't laugh
at me Wheeler dealers, becausethey deal with some of that
stuff And they buy cars thatjust recently bought an old I
don't remember what it was.
It was a triumph or somethingThat's by some of the weirdest
(13:12):
cars They did.
And that the engine was builtfor a leaded fuel And they would
put additives in it withouthaving to do anything to the
engine.
Well, one of the two of themactually, engines, little four
cylinder engines that really hadno horsepower at what per se
They wound up with having toconvert them, and convert them
(13:37):
really wasn't that big of a deal.
You take the head off and youstrengthen the, the valve seats,
and that's really all that theyneeded to do.
But it was a valve job on a carSo it was expensive to do
because you had to send it to amachine shop to do it And you
said that burning the fuel inthe manifold or in the exhaust
system before it got to thecatalytic converter.
Speaker 2 (13:57):
You said technologies way in advance to the today,
from the air pump We still havea catalytic converter.
Speaker 3 (14:03):
Oh yeah, we still have a catalytic converter.
Speaker 2 (14:04):
The technology on that piece of equipment has
increased, but you still havethat.
Speaker 3 (14:10):
And if you think about it, on the catalytic
converter you have two oxygensensors.
You have one before theconverter which is an oxygen
sensor.
Believe me, if they're replacingyour oxygen sensor, they may
not know what they're doing.
In oxygen sensor.
All it does is tell thecomputer how much oxygen's in
the exhaust stream, and thepurpose of that is efficiently
(14:31):
burn fuel.
There should be very littleoxygen in the exhaust stream.
Inefficiently burn fuel.
There's going to be a lot ofoxygen left in the exhaust
stream.
The O2 sensor tells thecomputer hey, there's a lot of
oxygen and it's going to adjustthe fuel mixture.
Or hey, there's very littleoxygen and it's going to adjust
the fuel mixture.
So if you get an O2 sensor code, first off it means the oxygen
(14:55):
sensor is working.
When the guy at Advanced AutoParts starts telling you an O2
sensor because you set a PO1702code, they're wrong.
The O2 sensor is working.
That's why it's set the code.
There's something else wrongwith the system.
The fuel delivery system tendsto be a vacuum leak or tends to
(15:16):
be an injector that's dripping.
Pick one.
That's generally where theissue is.
Speaker 4 (15:21):
I hate it when my injector drips, i know it.
Speaker 1 (15:23):
I have a pill for that, a little blue one.
No, not a blue one, it's alittle white one actually.
But at any rate, how aboutlet's talk about crank shafts
and let's talk about flat plane?
Okay?
Speaker 3 (15:38):
I'll do that for next week.
Speaker 1 (15:39):
And let's talk about this new engine that Chevrolet's
got in the Corvette the Z06engine.
Speaker 3 (15:46):
They call it a cross plane And I think the reason
they call it a cross plane isbecause I think flat plane is
trademarked already by Ford onthe Mustang with their flat
plane.
Speaker 1 (15:57):
Well, I'll tell you what it sounds like a sewing
machine going by, Oh yeah, Youknow what?
12,000 RPM or something.
It's crazy And I want to knowabout that Definitely.
Speaker 2 (16:04):
So let's do that Okay .
Speaker 1 (16:07):
I know that you need to incorporate camshafts with
that No no, the flat plane crank.
Speaker 4 (16:13):
Yeah, standard, crank the flat plane and this cross.
Yeah, and really, if you sayflat plane.
Speaker 3 (16:18):
It just means you know you ever had a crank shaft
out.
Speaker 4 (16:20):
Wait, wait, wait, say it next week.
Speaker 3 (16:23):
Yeah, next week It's all about the look of the
crankshaft, and is it?
Speaker 2 (16:28):
Corvette Pace car this year, and Indy, and isn't
it a hybrid or I can't remember.
I think it's the new Z06.
No, it's the Z06.
It's the Z06.
Okay.
Speaker 1 (16:35):
Anyway, thank you very much for that.
Speaker 2 (16:39):
Very cool Yeah.
Speaker 1 (16:40):
Yeah, very cool.
So next week we'll docrankshafts I think that would
be a good idea.
Yeah, more than 1.8 millionChrysler, dodge, jeep and Ram
vehicles now alert drivers inthe US and Canada of nearby fire
trucks, ambulances and roadhazards through their UConnect
(17:02):
infotainment system.
The idea of the feature camefrom a hearing impaired
Stalantus employee who nearlycollided with an emergency
vehicle.
She couldn't hear.
The employee in 2021 suggesteddriver notifications to help
avoid such calamities andStalantus deployed the emergency
vehicle alert system from Haasalert that it began rolling out
(17:24):
last year and, over the year,updated out of the system to
vehicles starting with the 2018model year.
Notifications came from Haasalert safety cloud platform, a
vehicle to everything anddigital alerting solution used
by thousands of public andprivate roadway fleets in North
America.
(17:45):
The warnings are triggered whenan emergency vehicle has its
lights or siren on.
Drivers zipping down thehighway won't be alerted to a
police vehicle simply parked onthe side of the road.
Stalantus is looking to expandthe alerts by adding disabled
vehicles to the list of hazards.
Drivers can be notified of thehazard enhanced location
(18:06):
protocol feature called helpcomes from emergency safety
solutions incorporated and usesthe Haas alert safety cloud.
That story from automotive newsand if you want any of these
more details on these stories,go to automotive newscom.
Speaker 3 (18:22):
Thank, you, which kind of goes to our earlier
interview today, summit Withsummit, about how the
interconnectivity of the vehicleand the data that can pass from
the vehicle to themanufacturing OEMs can also pass
from emergencies to the vehicle.
Speaker 2 (18:40):
Well, and also the vehicle that they couldn't hear,
assuming it's electric.
and who covers that insurance?
Speaker 1 (18:46):
Jeff's got a great story.
Oh some statistics that I thinkthat all of us have you ever
you have you ever hooked up inan honorable?
Speaker 2 (18:54):
be hooked up in a car .
Speaker 1 (18:56):
Shut up, mars.
You know, you know exactly.
The first person that has asmile on his face is Mars.
Speaker 2 (19:01):
I know Well the number one vehicle that is a
sedan 65.9% of people who hookedup in sedan, 40% of 40.6% of
people who hooked up in SUV, 30%in a coupe, 24% in a pickup
truck and 5% in a crossover.
Now, what about sport cars?
Speaker 4 (19:22):
I don't hear Volkswagen in there anywhere.
Speaker 2 (19:24):
Satisfaction by vehicle type is SUV number one.
Speaker 3 (19:28):
That's where you're most satisfied hooking up.
That's what the back seat says.
Speaker 2 (19:32):
They didn't get any detail, conrad, but the
percentage of Americans whohooked up in a vehicle, number
one is Ford 34.6% is a Ford,chevrolet's 31.5%.
To hook up in Mike, honda,toyota, dodge, nissan, all the
way down toa what Mercedes Benzat 4.2% of people in its lab.
Speaker 3 (19:52):
I am Spitfire GT6.
Speaker 2 (19:54):
If you're in a Mercedes, do it before tiny,
tiny little car before, asrecalled.
Then you get the Mercedes.
Where do Americans park to hookup, mike?
Where do they do that?
in Beaumont, well, parking lotis 56.1%, in a remote location
(20:14):
55% and a driveway 43.
On the side of the road, conrad35.1.
At a golf course scenicoverlook.
Hello sir, what are you doingin there?
Get out of there and a parkingto keep the rhythm right down.
Parking garage is 15.6%.
Okay, the best spots outside ofa vehicle?
(20:37):
Check this out at the campsiteon the trunk standing outside,
standing outside the vehiclewhile using the vehicle as
support.
Yep, the trunk on top of thecar or on top of the hood?
Speaker 1 (20:49):
Well, the hood, it kind of caves in.
Speaker 4 (20:51):
I would think the top would too.
Speaker 1 (20:53):
Yeah, but I'm thinking the trunk dent in it.
Speaker 2 (20:55):
Hold on.
I think I got more statistic.
Shut up, don't look at me thatway, Hey Leslie.
Oh no, All right.
Speaker 4 (21:07):
Why he keeps the cover on the car man.
I don't know.
Speaker 3 (21:11):
Why don't you look at it?
Speaker 4 (21:12):
How dirty it is right now.
I didn't look underneath thecover There are some different
kinds of prints on that.
Speaker 2 (21:18):
The best spots inside of a vehicle which includes the
coupe crossover sedan.
The back seat is 4.3%.
The trunk or hatch is 2.3.
On a pickup truck back seat orthe truck bed, passenger vehicle
passenger seat or the driver'sseat, and then same thing on the
back seat.
Speaker 1 (21:37):
There's nothing mentioned about the center
console.
Speaker 2 (21:39):
there, no, there's positions, but we're not going
to get into that right now.
Speaker 3 (21:43):
There's their positions The reverse cowgirl,
you can't do that You can't.
Speaker 2 (21:50):
Is it on there?
Speaker 4 (21:51):
It's on there.
Yeah, he spotted it.
Speaker 2 (21:53):
Oh wow We find it, you can have it.
Speaker 1 (21:54):
No, i'm not going to.
Yes, you are, you have to.
It's funny.
Speaker 2 (22:00):
It's this top graph.
There's a graph.
Well, it has different took.
Speaker 3 (22:03):
But, no pictures.
Speaker 1 (22:04):
Let me think now.
Speaker 3 (22:05):
Don wants the pictures.
Speaker 1 (22:06):
Okay, i got it.
Oh, you're sitting.
Cowgirl, reverse cowgirl,missionary.
Oh my God, there's evenspooning on here, Spooning
Mm-hmm, not forky.
Well, i know, i noticed thatyou, that you actually skipped
over.
I did skip over several.
You skipped over that.
Oh Oh, and they give explicitdiagrams in that.
(22:29):
Where did you get this?
Speaker 3 (22:31):
What playboy side is this off of I?
Speaker 4 (22:32):
know, a guy.
Speaker 1 (22:34):
You know a guy, i know a guy.
Speaker 3 (22:35):
Well, that's a pretty Todd's going to use it as an
instruction man.
Speaker 1 (22:38):
Hey, leslie, he's keeping a copy.
You know we're going to sendthis to HCC Community College
and the Electric VehicleAutonomy.
Speaker 2 (22:49):
Program There you go, send that over there.
Shocking, shocking.
Okay It's my contribution.
Speaker 1 (22:57):
That was a good one.
German authorities have seriousindications of possible data
protection violations by Tesla.
Handles Blatt newspaperreported, citing the data
protection office in the statewhere the car maker has its
European Gigafactory Files, hasfailed to adequately protect
data from customers, employeesand business partners, citing
100 gigabytes of confidentialdata leaked to the newspaper by

addresses, phone numbers,salaries of employees, bank
details of customers and secretdetails from production.
Filing the leaked files, thenewspaper reported about
(23:42):
thousands of customer complaintsregarding the car maker's
driver assistance systems, witharound 4,000 complaints on
unintended acceleration orphantom braking.
Last month, reuters reportshowed the groups of Tesla
employees privately shared, viaan internal messaging system,
sometimes highly invasive videosand images recorded by
customers car in-car camerasbetween 2019 and 2022.
(24:07):
I think that goes along withyour story.
Speaker 2 (24:08):
You have to think of the same thing.
Speaker 1 (24:09):
Data protection office in the German state of
Brandenburg, which is home toTesla's European factory,
described the data leak asmassive.
Speaker 3 (24:17):
Videos of Holga.
Speaker 1 (24:18):
Holga, holga.
Speaker 2 (24:20):
Holga, holga.
Speaker 1 (24:23):
Yes, i worked with a girl by the name of Holga, and
radio station.
No at a television station.
Speaker 3 (24:31):
She's still around.
Speaker 1 (24:32):
She is.
She's still on TV Up for her.
Speaker 3 (24:34):
Down in Florida, somewhere, i think.
Speaker 1 (24:35):
Wonderful.
At any rate, we're going totake a break now.
Speaker 2 (24:40):
Okay, i hope.
Speaker 3 (24:42):
That was an exciting segment.
I'll see you.
Speaker 1 (24:45):
I'll try to do better next week.

Tesla's surprise agreement withrival Ford to provide access to
the Tesla supercharger networkopens the door for other
automakers to follow suit.
About 17,000 chargingconnectors Tesla has the largest
and most reliable fast chargenetwork in the US.
Ford customers will gain accessto roughly 1200 next year as
(25:07):
part of the first such agreementbetween Tesla and another
automaker.
The deal with Tesla, withadditional customers and revenue
for its coast to coastinfrastructure of direct current
chargers, which makes roadtrips and long commutes possible
, more than doubles the numberof fast charger plugs available
to Ford customers from allcharging partners.
We'll be back after this.

It's gonna be a beautifulweekend, holiday stuff, jeff's
birthday spanking.
Speaker 3 (01:02):
Spanking, so you can get that on the subscription
side.
Speaker 1 (01:07):
Behind the scenes make sure to say $10,000 to my
secret account and wherever soevery week we have Conrad do a
thing called the in wheel timecar clinic.
Gives you a little bit moredetailed information about
certain things about cars fromthe rear end.
Speaking of rear ends, Hey, heyhey, all the way up to the front
(01:29):
bumper.
And so I, conrad and I weretalking a couple of weeks ago
And I said why don't we get morespecific about certain engine
things?
and I brought up piston ringsand I thought that piston ring
thing was Very interesting.
I ran across the story aboutthe new evolution of piston
rings and Material makeup ofthem, the size of them, the, the
(01:52):
tension stuff, all of the stuffabout what they do And what
they do.
And it's not just one ring.
Speaker 3 (01:58):
But this week we're going to talk about pistons and
there are all sorts of differenttypes of pistons Depending on
the usage right, you know, ifyou kind of go back um into the
50s and 60s, compression ratioswere, you know, eight, nine to
one In the later 60s might havegot up to 10 or 11 to one, um,
(02:20):
and then, uh, you know, and thenwe've moved on up into the new
cars where you might see as highas 18 to one compression.
Well, one of the first pistonsthat were out there used was
what there was called the flattop piston.
There's, there's nothing on topof this piston is basically
flat and in some instances Theremay be some valve reliefs in
the piston and that's just togive a little bit of clearance
(02:41):
for The valves as they open andclose and they'll cut these
little notches in the valve inthe top of the piston for that
Valve relief.
This is very common lookingpiston out there In the industry
was a very common lookingpiston in the industry.
And uh, and then you, you knowwhat year, what year was that?
what year?
probably 60s, mid, mid 60s, yeah, and then you know, and then
(03:04):
the hemi and the hemi, thehemispherical combustion chamber
changed at all You know we'vegot valves that are on both
sides of massive ones, massive,huge valves, and in this case I
imagine this is probably a topfuel because there's you know
it's so highly domed Um and thatit's really a high compression
and pretty big reliefs cut inthe piston.
Speaker 2 (03:24):
When I see in that country the valves, multiple
slots for multiple rings Forcompression for three
compression rings and one oilring on it.
Speaker 3 (03:34):
So that's the hemi.
The next one would be the wedgeengine.
So you always heard the wedgeengine, uh, as the mo, par 440s,
maybe even the chevrolet bigblocks.
So there would be basically awedge on top of the piston with
valve reliefs cut into it againthat that Lift off of the base
of the piston is all aboutincreasing the compression ratio
(03:55):
, filling up the combustionchamber with metal To raise the
compression ratio on the engine.
So you're filling up the volumewith something with metal, yeah
right, and then and then again,the uh, um, the the notched, or
the uh the notched piston wasprobably the most popular over
time.
Well, now they've moved to umgasoline direct injected engines
(04:20):
.
And the gasoline directinjected engine, the piston has
a different function, where whatthey want is the fuel injector
sprays into that, what I'll callthe bathtub, right there in the
center of that, in the centerof that piston, and what it's
trying to do when the injectionsprays into there, it's trying
to bounce it all back up into.
(04:40):
Now.
I'm a star Uh trek fan, not astar wars fan.
So in star trek, you know, theyshoot the photon torpedo.
Little ball of energy.
So in this, in the gdi engine,they're trying to create a
little ball of air fuel mixtureright there at the spark, right
there at the tip of the sparkplug, which is a wonderful way
(05:00):
to do it.
The the issue with it is itmeans all of that outside area
gets very hot because it runsvery, very lean And in that.
So if you looked at how theinjector sprays on top of the
piston on a gdi engine, you'llsee that the injector sprays
into the middle of the pistonand it brings that whole air
fuel ratio Powerball right tothe tip of the spark plug.
(05:22):
So when the spark plug ignitesIt's got the proper air fuel
ratio, basically to create anexplosion that pushes the piston
down.
Speaker 2 (05:29):
So the, the, the pistons coming up with the
reservoir of fuel is what it'sdoing into that injector.
Speaker 3 (05:34):
Well, now it's coming up with a reservoir of air,
okay, and then the injectorsprays at a very high pressure
and really highly atomized rightthere at the top of the stroke.
Speaker 1 (05:43):
Yeah, right there at the top of the stroke and that
that puts the.
Speaker 3 (05:46):
Now this is a port fuel injection system.
So you can see there theinjector is behind the valve so
it sprays in on top of the valveAnd then it kind of fills the
combustion chamber.
That was a big thing in the 80s, right?
Yeah, port fuel was primarilyintroduced in the early 80s and
then there was the directinjected engine and my fault.
(06:08):
The yellow injector would dropdown underneath the valve and
the direct injected engine Wouldspray directly into the
combustion chambers.
That's why the compressionratio Being so high and the fuel
pressure is being so high, tobring that all in, and and the
technology is now that that WhatI call the bathtub is all
(06:28):
designed to reflect the fuelspray all up to the tip of the
spark plug, so they could useless fuel Still, get the correct
amount of air fuel mixture atthe tip of the spark plug To
push the piston down, and that'swhere the fuel economy benefits
come from the same burn powerwith less fuel with less fuel.
But the the you know, for everyaction there's an opposite and
(06:52):
opposite reaction.
The opposite reaction is thearea outside of where that fuel
is is very lean, and whencombustion temp, combustion goes
lean, it goes hot.
So you got to remember allaround that outside of that
piston is where the ringlandsare.
So that's where the problemcomes, with carbon deposits in
the ringlands and ring stickingand and Blow by.
(07:13):
And you know, with blow by youget gasoline in your oil, which
makes your oil more vaporous.
So it it evaporates faster aswell as gets sucked up through
the PCV system.
Speaker 4 (07:24):
So why not make the pistons smaller so you don't
have to deal with that heat onthe outside, because you still
have the same burn and you still, but you lose power.
Speaker 3 (07:35):
Right, you don't have enough surface, right well, and
one of the other big thingsthey did in the technology of
pistons is they have changed thelength of the skirt On a piston
.
So the skirt on a piston iswhat kept the piston from
rocking back and forth.
So in In one of those picturesand I forgot to get to it It
showed that they've actually puta Polymer pad on the side of
(07:59):
the piston to kind of fill inthat space, because a piston
skirt, when the piston gets hot,grows and and gets larger so
that the piston fits thecylinder better.
Well, there's a.
You know, a lot of engines havewhat's called a piston slap
when they're cold.
So this, this polymer pad, isdesigned to deal with that
piston slap, so that there's nowobble.
(08:20):
There's no wobble, you know,and it's kind of like Don and
Jeff.
They have short skirts as well.
Speaker 1 (08:26):
I have to tell you that my dad worked for a company
called walk a Shaw MotorCompany, and They developed
industrial engines all sorts ofsizes, from a little small four
cylinder that actually wasdeveloped to start Great, big,
huge, 12 and 16 cylinder enginesthat wouldn't even fit in this
(08:47):
room They're so big and heworked in the laboratory and in
the laboratory.
They did all of the testing andfound out you know, the best
way to fuel of them.
Many of them were Gasolinedriven, most of them were
diesels, some of them were gasnatural gas driven engines.
And He was in this laboratorywhere they actually blew up
(09:11):
engines and then they looked atthe damage and what caused it to
blow up.
Was it the RPM?
what couldn't handle the RPM?
The most efficient way to getinjection into Right all of that
and all of those were prettymuch injected engines back in
the day And I think that theystill are, that that company has
(09:33):
changed hands and dresserbought them and moved the
factory up I think up to Canada,but at any rate he worked in
the laboratory and that's whatthey did.
Speaker 3 (09:40):
And I'm sure your dad would would enjoy that piece,
because I'm sure he saw most ofthis evolve in his hands as The
design of engines changed overtime.
So pistons around.
Speaker 2 (09:53):
We get that not all.
I was gonna say They aren'tthere, some that are oval Yeah.
Speaker 3 (09:57):
Honda.
Honda made a racing motorcyclewith an oval shaped right.
Speaker 4 (10:03):
It was a v4 engine and a kidney bean shape It ended
up being outlawed because itwas just too.
Speaker 3 (10:10):
Radical yeah to advance for everything.
Speaker 1 (10:12):
Why would you do that ?
save space.
Speaker 3 (10:14):
Well, to save space.
But also you know you talkedabout the surface area, right Is
what creates the power.
So it gave them an opportunityto make more surface area on the
piston in a smaller Gotchacombustion area compartment,
right, yeah, because it's allabout size Of the engine as well
as size of what you're doinginside the engine.
Speaker 4 (10:35):
So let me ask you this so back, you know, 69, 70,
71, you know we were trying to,we were putting flat tops in, we
were trying to get compressionratios up 11, 12 to 1 or
something like that.
But then when the smog worldcame in, everything dropped to
like eight right and a half orsome so And now it's kind of
cycle where it's coming back up.
What, yeah?
(10:55):
Why?
why did that?
why did they do?
Speaker 3 (10:58):
that if?
Speaker 4 (10:59):
it's more efficient at the higher compression ratios
.
Speaker 3 (11:01):
Well, it's more efficient because the fuel
delivery systems are moreefficient today.
Back then, when you were doingthat, you were doing a Holley or
a Quadrajet, maybe even aCarter if you were high tech.
Speaker 4 (11:14):
We had Holley's as far as we got.
Speaker 2 (11:16):
Whatever they could get out of the junkyard.
Speaker 3 (11:18):
A carburetor spray is not an efficient fuel delivery
system.
It may work correctly, butthey're not an efficient fuel
delivery system.
They had to lower thecompression ratio to make sure
more of it burned efficiently sothe catalytic converter could
clean it up.
Today they can get a good,clean burn because they're
(11:39):
spraying much less fuel in tocreate remember what I said a
little photon torpedo rightthere at the tip of the spark
plug That burns more efficiently, so they can raise the
compression ratio and not haveto worry about unburned fuel
passing through the exhaust,which is the exhaust emissions
that the federal government'sconcerned.
Speaker 4 (11:57):
I knew it had something to do with the smog I
mean, that's what everybody said, oh, it's a smog, Take the smog
stuff off but didn't reallyunderstand the reasoning.
Speaker 1 (12:06):
They don't even use that technology and air pumps
and stuff like that.
Speaker 3 (12:09):
That's what I was just about to say.
You got to remember, back inthose days you had an air pump.
You actually had a belt drivenpump on the front of the engine
that pumped oxygenated air intothe exhaust manifold, trying to
burn off that unburned fuel Ordilute it.
No, actually trying to burn it.
I'll try to light it up andburn it off in the exhaust
(12:30):
stream as it was headed for thecatalytic converter.
Even before catalyticconverters, that air pump was
part of it.
Air injection reaction is whatair stood for, because they were
just literally trying to keepthe burn happening to kind of
clean up, If you stop and thinkabout all of that, how far we've
come in such a really a shortperiod of time.
Speaker 1 (12:51):
Right, You know, some of my favorite car shows are
The Restores show And alsobelieve it or not, don't laugh
at me Wheeler dealers, becausethey deal with some of that
stuff And they buy cars thatjust recently bought an old I
don't remember what it was.
It was a triumph or somethingThat's by some of the weirdest
(13:12):
cars They did.
And that the engine was builtfor a leaded fuel And they would
put additives in it withouthaving to do anything to the
engine.
Well, one of the two of themactually, engines, little four
cylinder engines that really hadno horsepower at what per se
They wound up with having toconvert them, and convert them
(13:37):
really wasn't that big of a deal.
You take the head off and youstrengthen the, the valve seats,
and that's really all that theyneeded to do.
But it was a valve job on a carSo it was expensive to do
because you had to send it to amachine shop to do it And you
said that burning the fuel inthe manifold or in the exhaust
system before it got to thecatalytic converter.
Speaker 2 (13:57):
You said technologies way in advance to the today,
from the air pump We still havea catalytic converter.
Speaker 3 (14:03):
Oh yeah, we still have a catalytic converter.
Speaker 2 (14:04):
The technology on that piece of equipment has
increased, but you still havethat.
Speaker 3 (14:10):
And if you think about it, on the catalytic
converter you have two oxygensensors.
You have one before theconverter which is an oxygen
sensor.
Believe me, if they're replacingyour oxygen sensor, they may
not know what they're doing.
In oxygen sensor.
All it does is tell thecomputer how much oxygen's in
the exhaust stream, and thepurpose of that is efficiently
(14:31):
burn fuel.
There should be very littleoxygen in the exhaust stream.
Inefficiently burn fuel.
There's going to be a lot ofoxygen left in the exhaust
stream.
The O2 sensor tells thecomputer hey, there's a lot of
oxygen and it's going to adjustthe fuel mixture.
Or hey, there's very littleoxygen and it's going to adjust
the fuel mixture.
So if you get an O2 sensor code, first off it means the oxygen
(14:55):
sensor is working.
When the guy at Advanced AutoParts starts telling you an O2
sensor because you set a PO1702code, they're wrong.
The O2 sensor is working.
That's why it's set the code.
There's something else wrongwith the system.
The fuel delivery system tendsto be a vacuum leak or tends to
(15:16):
be an injector that's dripping.
Pick one.
That's generally where theissue is.
Speaker 4 (15:21):
I hate it when my injector drips, i know it.
Speaker 1 (15:23):
I have a pill for that, a little blue one.
No, not a blue one, it's alittle white one actually.
But at any rate, how aboutlet's talk about crank shafts
and let's talk about flat plane?
Okay?
Speaker 3 (15:38):
I'll do that for next week.
Speaker 1 (15:39):
And let's talk about this new engine that Chevrolet's
got in the Corvette the Z06engine.
Speaker 3 (15:46):
They call it a cross plane And I think the reason
they call it a cross plane isbecause I think flat plane is
trademarked already by Ford onthe Mustang with their flat
plane.
Speaker 1 (15:57):
Well, I'll tell you what it sounds like a sewing
machine going by, Oh yeah, Youknow what?
12,000 RPM or something.
It's crazy And I want to knowabout that Definitely.
Speaker 2 (16:04):
So let's do that Okay .
Speaker 1 (16:07):
I know that you need to incorporate camshafts with
that No no, the flat plane crank.
Speaker 4 (16:13):
Yeah, standard, crank the flat plane and this cross.
Yeah, and really, if you sayflat plane.
Speaker 3 (16:18):
It just means you know you ever had a crank shaft
out.
Speaker 4 (16:20):
Wait, wait, wait, say it next week.
Speaker 3 (16:23):
Yeah, next week It's all about the look of the
crankshaft, and is it?
Speaker 2 (16:28):
Corvette Pace car this year, and Indy, and isn't
it a hybrid or I can't remember.
I think it's the new Z06.
No, it's the Z06.
It's the Z06.
Okay.
Speaker 1 (16:35):
Anyway, thank you very much for that.
Speaker 2 (16:39):
Very cool Yeah.
Speaker 1 (16:40):
Yeah, very cool.
So next week we'll docrankshafts I think that would
be a good idea.
Yeah, more than 1.8 millionChrysler, dodge, jeep and Ram
vehicles now alert drivers inthe US and Canada of nearby fire
trucks, ambulances and roadhazards through their UConnect
(17:02):
infotainment system.
The idea of the feature camefrom a hearing impaired
Stalantus employee who nearlycollided with an emergency
vehicle.
She couldn't hear.
The employee in 2021 suggesteddriver notifications to help
avoid such calamities andStalantus deployed the emergency
vehicle alert system from Haasalert that it began rolling out
(17:24):
last year and, over the year,updated out of the system to
vehicles starting with the 2018model year.
Notifications came from Haasalert safety cloud platform, a
vehicle to everything anddigital alerting solution used
by thousands of public andprivate roadway fleets in North
America.
(17:45):
The warnings are triggered whenan emergency vehicle has its
lights or siren on.
Drivers zipping down thehighway won't be alerted to a
police vehicle simply parked onthe side of the road.
Stalantus is looking to expandthe alerts by adding disabled
vehicles to the list of hazards.
Drivers can be notified of thehazard enhanced location
(18:06):
protocol feature called helpcomes from emergency safety
solutions incorporated and usesthe Haas alert safety cloud.
That story from automotive newsand if you want any of these
more details on these stories,go to automotive newscom.
Speaker 3 (18:22):
Thank, you, which kind of goes to our earlier
interview today, summit Withsummit, about how the
interconnectivity of the vehicleand the data that can pass from
the vehicle to themanufacturing OEMs can also pass
from emergencies to the vehicle.
Speaker 2 (18:40):
Well, and also the vehicle that they couldn't hear,
assuming it's electric.
and who covers that insurance?
Speaker 1 (18:46):
Jeff's got a great story.
Oh some statistics that I thinkthat all of us have you ever
you have you ever hooked up inan honorable?
Speaker 2 (18:54):
