Starting system
To make the engine transition from a static state to a working state, the crankshaft of the engine must be rotated by external force to make the piston reciprocate. The engine can run on its own and the work cycle can proceed automatically. Therefore, the whole process from when the crankshaft starts to rotate under the action of external force to when the engine starts to automatically idling is called starting of the engine. The device required to complete the starting process is called the starting system of the engine.
The gasoline engine is composed of the above two major mechanisms and five major systems, namely, the crank connecting rod mechanism, the valve mechanism, the fuel supply system, the lubrication system, the cooling system, the ignition system and the starting system; the diesel engine is composed of the above two major mechanisms and the four major systems. , that is, it consists of a crank connecting rod mechanism, a valve mechanism, a fuel supply system, a lubrication system, a cooling system and a starting system. The diesel engine is compression-ignition and does not require an ignition system.
