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.
