Basic process
As their name implies, operation of a four stroke internal combustion engines have 4 basic steps that repeat with every two revolutions of the engine:
 * 1) Intake
 * 2) *Combustible mixtures are emplaced in the combustion chamber
 * 3) Compression
 * 4) *The mixtures are placed under pressure
 * 5) Combustion/Expansion
 * 6) *The mixture is burnt, almost invariably a deflagration, although a few systems involve detonation. The hot mixture is expanded, pressing on and moving parts of the engine and performing useful work.
 * 7) Exhaust
 * 8) *The cooled combustion products are exhausted into the atmosphere

Many engines overlap these steps in time, jet engines do all steps simultaneously at different parts of the engines.
