What is IC Engine??

Engine

ICE is a heat engine that converts chemical energy in a fuel into mechanical

energy.

Chemical energy in fuel is first converted to thermal energy by means of

combustion.

Thermal energy raises the temperature and pressure of the gas inside the

cylinder.

The high pressure gas expands against the mechanical mechanisms (linkage) of

the engine.

The mechanical linkage rotates a crankshaft which is connected to the

transmission or power train for the final mechanical output.
