Explanation
An engine is a machine that makes vehicles, machines, or tools move or work. Cars, motorcycles, boats, and airplanes all use engines to run. Engines can use fuel like petrol, diesel, or electricity. For example, the engine makes the car move, and the accelerator pedal tells the engine how fast to go. Engines are also found in machines like lawnmowers or generators. Without an engine, these machines would not work. The word “engine” can also be used to describe something that drives or powers progress, like “Discipline is an engine of growth”.
