Nitrous oxide (N
2
O): Nitrous Oxide (N2O), or Dinitrogen Monoxide, is a chemical compound that is
commonly used in racing applications to increase the power output of an
engine. Nitrous oxide is used in internal combustion engine applications to
increase the amount of oxygen available in the combustion chamber for
burning fuel. The air that we breath in everyday is composed of roughly 78%
nitrogen, 21% oxygen, and 1% miscellaneous gases. Nitrous Oxide, on the
other hand, is composed of roughly 64% nitrogen and 36% oxygen. Because
nitrous oxide has a higher concentration of oxygen than air, more fuel can be
injected into the combustion chambers, creating more power output from the
engine. Also, nitrous is undergoing a phase change which cools the engine
inlet air and increases the charge density, further increasing the amount of
oxygen available for combustion.
Throttle Position Sensor
(TPS):
The Throttle Position Sensor (TPS) is the sensor that monitors the position or
the angle of the throttle blade. The throttle position sensor sends a signal,
usually between 0-5 volts, to the ECM or PCM telling it to what degree the
throttle valve is open. Electronic throttle bodies (also known as "drive by
wire") generally have two sensors. One of the sensors will output an
increasing signal as the throttle opens while the other sensor will output a
decreasing signal. This allows the ECM of PCM to compare the two signals to
verify that the data is correct.
