An internal combustion engine (ICE) is a type of heat engine that generates mechanical power by burning a fuel and air mixture within a combustion chamber. These engines are widely used in various vehicles and machinery, including cars, trucks, motorcycles, boats, and many industrial applications. The key principle behind an internal combustion engine is the controlled explosion of a fuel-air mixture, which produces high-pressure gases that act on a piston or rotor, converting chemical energy into mechanical work.

Here are the main components and processes involved in an internal combustion engine:

Combustion Chamber: This is where the fuel and air are mixed, ignited, and burned. The combustion chamber can vary in design, with configurations like cylinders in a reciprocating engine or combustion chambers in a gas turbine engine.

Fuel and Air Intake: The engine draws in a mixture of fuel and air through an intake system. The ratio of fuel to air is carefully controlled to ensure efficient combustion.
