The main job of fuel and air/oxygen in IC engine is to heat
the Gas to expand and produce power. The fuel makes around
14% mass of mixture and oxygen make around approx 23% and
remaining is nitrogen(63%) from air. If Nitrogen is
eliminated from the equation, more fuel-oxygen is required
to produce same power. But burning more fuel-oxygen will
produce very high amount of heat, a problem to deal with.
Nitrogen in air acts as an expanding medium, similar to
steam in thermal power plant. It absorbs heat of combustion
and expands, (like a inert fluid medium) to provide power
and at the same time keep the engine temp in desired limit.
