IC engine means the combustion is takes place inside the combustion chamber it has been divide in two types one is CI engine and SI engine. CI means compression ignition Engine (Ex Diesel Engine) and SI engine (Ex Petrol Engine) means spark ignition engine. In CI engine the air get compressed (compression ratio is 1:10) in combustion chamber according to thermodynamics Pressure and temperature are directly propositional it means pressure increased and temperature also increased that time the atomization (fine spraying) diesel will injected into combustion chamber ignition will takes places. SI engine charge (the mixture of petrol and Air from corroborator) gets compressed (compression ratio is 1:4) in combustion chamber that time spark will come with help of spark plug ignition will takes place
