In order to make a stationary engine work, it is necessary to use external force to rotate the engine crankshaft, so that the piston starts to move up and down, the cylinder sucks in combustible mixture, and then enters the subsequent work cycle in turn. The external force system it relies on is the startup system.
At present, almost all automobile engines are started by electric starters. When the drive gear on the motor shaft meshes with the ring teeth on the periphery of the engine flywheel, the electromagnetic torque generated when the motor rotates is transmitted to the crankshaft of the engine through the flywheel to start the engine. Electric starter is referred to as starter. It uses storage battery as power source, simple structure, convenient operation, fast and reliable starting.
