(1) If the starting system wants to change the engine a stationary state to a working state, it first needs to use external force to rotate the engine's crankshaft, so that the piston can make repeated movements. The combustible mixture in the cylinder burns expands to work, pushing the piston downward to rotate the crankshaft. The engine can only operate on its own, the working cycle can only proceed on its own. Therefore, the entire process of the crankshaft starting to rotate under external force until the engine starts to automatically idle is called engine starting, the device required to complete the starting process is called the engine starting system.

(2) The function of the fuel supply system for gasoline engines is to prepare a certain amount concentration of mixed gas according to the requirements of the engine, supply it into the cylinder, exhaust the burnt mixture the cylinder; The function of the diesel engine fuel supply system is to separately supply diesel air into the cylinder, form a mixture in the combustion chamber burn it, finally exhaust the burnt exhaust gas.

(3) The function of the cooling system is to timely dissipate some of the heat absorbed by the heated parts, ensuring that the engine operates at the most suitable temperature state. The cooling system of a water-cooled engine usually consists of components such as a cooling water jacket, water pump, fan, water tank, thermostat, etc.

(4) The function of the lubrication system is to transport a quantitative amount of situational lubricating oil on the surface of relatively moving parts, in order to achieve liquid friction, reduce frictional resistance, reduce the wear of machine parts. Clean cool the surface of automotive aluminum profiles. The lubrication system is usually composed of lubricating oil ducts, oil filters, gasoline pumps, some valves.

(5) In a gasoline engine, the combustible mixture in the cylinder is ignited by an electric spark. Therefore, a spark plug is installed on the cylinder head of the gasoline engine, the head of the spark plug extends into the combustion chamber. All equipment that can generate electric spark between spark plug electrodes on time is called ignition system, which is usually composed of generator, battery, Distributor, ignition coil, spark plug other parts.
