Engines can need a variety of systems to support their operation, including: Cooling systems to stop the engine from overheating; lubrication Systems to prevent wear and tear on moving parts (reduce friction between parts and allow movement with less energy loss); ignition systems provide a spark of electricity to ignite petrol; and transmission systems transmit power/movement from the point of production to the point of use (e.g. Wheels of a tractor).
