It is controled by the cars ECU (computer) The air fuel ratio on a car cahnges depending on RPM , load on the motor , and air tempature. http://en.wikipedia.org/wiki/Air_fuel_ratio

The engine computer is in control.
It ignites the compressed air/fuel mixture.
It get's richer, The fuel/air mixture becomes richer..

install a cold air intake. more air with same amount of fuel being injected will lean out the fuel/air mixture. plus you'll get more power
The purpose of the spark is to ignite the air fuel mixture in the combustion chamber. When the air fuel mixture ignites the expansion of the burning air fuel mixture causes the piston to go down thus turning the crankshaft.
Mixture strength in combustion refers to the ratio of fuel to air present in the air-fuel mixture. It can impact the efficiency and performance of the combustion process, with a stoichiometric mixture (ideal ratio of fuel to air) typically providing optimal results. Adjusting the mixture strength can affect factors like power output, emissions, and fuel economy in combustion engines.
It is ignited by compression. The air fuel mixture is compressed by the piston going up. Some diesels have glow plugs too that heat up the air fuel mixture so it is more easily ignited.
The methods to control the fuel and air mixture in a carburetor include needle valves to control fuel flow, and the butterfly or ventura to control air flow.
