Welcome to brain Stuff from how stuff works dot com,
where smart happens Him Marshall Brain with today's question, how
does nitrous oxide help an engine perform better? It turns
out that nitrous oxide is a great source of oxygen.
(00:23):
When you heat nitrous oxide to about five seventy degrees fahrenheit,
it splits into oxygen and nitrogen. So the injection of
nitrous oxide into an engine means that more oxygen is
available during combustion. Because you have more oxygen, you can
also inject more fuel, allowing the same engine to produce
more power. Nitrous Oxide is one of the simplest ways
(00:46):
to provide a significant horsepower boost to any gasoline engine.
Nitrous oxide has another effect that improves performance even more.
When it vaporizes, nitrous oxide provides a significant cooling effect
on the intake air. When you reduce the intake air temperature,
you increase the air's density, and this provides even more
(01:07):
oxygen inside the cylinder. The only problem with nitrous oxide
is that it's fairly bulky and the engine needs a
lot of it. Like any gas, it takes up a
fair amount of space even when compressed into a liquid.
A five liter engine running at four thousand rotations per
minute consumes about ten thousand liters of air every minute,
(01:29):
compared to about point two liters of gasoline, so it
would take a tremendous amount of nitrous oxide to run
a car continuously. Therefore, a car normally carries only a
few minutes of nitrous oxide, and the driver uses it
very selectively by pushing a button. Be sure to check

Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
