combustion engine

A combustion engine is a machine that converts fuel into energy to power vehicles and other equipment. It works by burning fuel (such as gasoline or diesel) inside a cylinder, creating hot gases that push a piston. This movement turns a crankshaft and ultimately powers the wheels of a car or other machinery. There are two main types of combustion engines: internal combustion engines, which have the fuel burn inside the engine itself, and external combustion engines, which burn fuel outside to heat another substance. Overall, combustion engines are essential for modern transportation and many industrial applications.
