There is approx 79% nitrogen in air as well as roughly 21% oxygen. When fuel is burnt in an automobile engine the oxygen reacts with the fuel producing heat and increased pressure/expansion of the gases in the cylinder. The nitrogen is rather a dampening factor (with pure oxygen engines could be smaller and more efficient but would need much more efficient cooling to prevent metallic parts overheating). A very small amount of nitrogen reacts with oxygen to produce various oxides of nitrogen (known as NOX). The amount of NOX formed will depend on factors such as residence time and prevailing temperatures. NOX in the atmosphere can trigger photochemical smog.

Nitrogen, or nitrous oxide? Nitrous oxide could make a car go faster for a short period of time, but it's also a great way to launch the heads out of the engine compartment.
Nitrogen is part of the atmosphere and is inert. The exhaust is returned to the intake to help reduce emissions. In effect, it poisons the air-fuel mix to reduce the the amount of nitrogen oxides produced.

No role to play
Since, it is part of the atmospheric air (21% oxygen, 79% Nitrogen,), we cannot do anything about it. But, it plays a spoilsport by getting oxidised to Nitrous oxides and becoming a pollution agent.

we'd advance peas on our acreage in oklahoma to restoration the nitrogen from the air to the soil. It exhibits up on specific beans and peas interior the roots, as knotted modules that are basic to tug up and % out interior the sphere. Then after harvest the whole plant is plowed decrease than and enables the nitrogent to be absorbed into the soil for the subsequent crop.

Hi
It is nitrous oxide. The emphasis is on the 'oxygen' bit. NO2 is injected into the engine and the additional oxygen is burnt to increase power. It has the potential to damage the engine so it is not constantly injected.

im pretty sure its to make cars go faster....like in races!
right on! peace<3
