defined maximum value set at 16000 RPM. The illustration has a 5%
hysteresis, which is shown by the dotted navy line. Once the nitrous is
disabled, it will not re-enable until the set point minus the hysteresis is
reached.
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.
