Plural
engines
1
the part of a vehicle that uses a particular fuel to make the vehicle move
An engine is a machine that converts fuel into power to make a vehicle run. In most vehicles, the engine burns fuel, such as gasoline or diesel, to create energy. This energy is then used to move parts like pistons, which turn the wheels. The engine is often considered the heart of a vehicle because it powers all its movements. The performance of the engine, such as how efficiently it uses fuel and how much power it produces, directly affects how well the vehicle runs.
