What are the auxiliary systems of automobile engines?

The engine has a starting system, an ignition system, a lubrication system, a cooling system, a fuel system, a crank-connecting rod mechanism and a valve train.

1, the starting system is mainly composed of a starter, which is connected with the engine flywheel;

2. The cooling system is mainly composed of water pump, water tank and cooling pipe, and its function is to circulate cooling water so as to avoid damaging the engine due to excessive temperature;

3. The lubrication system is mainly composed of engine oil pan, oil filter and oil collector, and its main function is to filter and lubricate the crankshaft, connecting rod and piston of the engine to avoid burning the engine due to overheating; Meanwhile, the friction enhancement loss is reduced;

4. The ignition system is mainly composed of a high-voltage coil and a spark plug, and its function is to convert the low-voltage current of the battery into high-voltage electricity, and then make the spark plug contact strike a light to ignite the mixture;

5. The supply system is mainly composed of oil tank, oil pipe, pipeline and carburetor, and its function is to supply fuel.
