A petrol motor, also known as a gasoline engine, is an internal combustion engine that uses petroleum-based fuel called petrol to power itself. This type of engine burns the mixture of air and petrol in its cylinders to create mechanical energy which is then used to move the vehicle's wheels or perform other work. Petrol motors are commonly found in automobiles, motorcycles, boats, lawn mowers, and many other types of vehicles that require a portable source of power.
