What is the working principle of an IC engine?

Question

Accepted Answer

IC engine is an internal combustion engine that converts chemical energy into mechanical energy.

IC engine works by burning fuel inside a combustion chamber to create high-pressure gases that push a piston, which in turn rotates a crankshaft to produce power.
There are two types of IC engines - spark-ignition engines (petrol engines) and compression-ignition engines (diesel engines).
IC engines are commonly used in automobiles, motorcycles, boats, and small aircraft.
The efficiency of an IC engine is measured by its thermal efficiency, which is the ratio of the work output to the heat input.
IC engines require regular maintenance and can produce harmful emissions, which has led to the development of alternative power sources such as electric motors and fuel cells.

Accepted Answer

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with in oxidizer in a combustion.
