Now what would be an automotive blog without nitrous? Nitrous
oxide is chemical compound with the formula N2O. More
commonly nitrous oxide is called laughing gas, nitrous, nitro, or NOS.
There are different uses for nitrous oxide which include medicinal uses (an
aesthetic for surgery and dentistry), aerosol, internal combustion, and for
other recreational uses.
For Internal combustion uses, nitrous is used to increase
the power output of your car’s engine. First let me explain how it does this.
Nitrous is stored as a liquid form inside nitrous canisters. When the nitrous
is released into the engine, usually from the intake manifold, it will turn
into a gas form and cool down the engine. When it does this, it produces more oxygen
for the engine to burn, causing the engine to work harder and produce more
power. Nitrous kits can be categorized into two types, Dry or Wet. A Dry system
just injects nitrous into the intake manifold, while a Wet system injects nitrous
(N2O) and fuel into the intake.
One of the major problems of using nitrous oxide, is that it
can produce enough power to damage or destroy the engine. It is very important
when using nitrous, to maintain proper operating temperatures and
fuel levels to prevent "pre-ignition", or "detonation"
(which is known as a "knock"). Since nitrous allows a much denser
charge into the cylinder it dramatically increases cylinder pressures. The
increased pressure and temperature can cause problems such as melting the
piston or valves, crack or warp the piston or head, and cause pre-ignition due
to uneven heating.
