3. 1. Introduction
The IC engine is Internal Combustion engine. The combustion of fuel occurs inside the
engine's cylinders, where a mixture of fuel and air is ignited, creating high- pressure gases
that push a piston. An IC Engine is a machine that transforms the energy released from the
combustion of fuel into mechanical energy. The motion of the piston is then converted into
rotary motion by a crankshaft, which can be used to drive a wide range of machines and
vehicles. IC engines come in different types, including reciprocating engines, such as spark
ignition engines and diesel engines, and rotary engines, such as the Wankel engine.
