Internal combustion engine

An internal combustion engine is like a very powerful machine that helps power cars and other vehicles. It has lots of different parts inside it that work together to create energy. The engine has a cylinder that is filled with fuel, like gasoline. When the fuel and air inside the cylinder are ignited, like a spark, they mix and create an explosion. This explosion helps to push a piston, which turns a crankshaft and creates energy that powers the car or vehicle.
