What is an Engine Starter?

The starter (starter) is also called a motor. It is powered by a DC motor, and the power is transmitted to the flywheel ring through the starter gear, which drives the flywheel and the crankshaft to rotate and start the engine. Its function is to convert electrical energy into kinetic energy when the key is turned to the start position, thereby starting the engine.

Starter Maintenance

In the process of starting the engine, the starter needs to introduce 300~400 Ah electricity from the battery. Therefore, in order to prevent the battery from being over-current or damaged, the starting time should not exceed 5s; When starting each time, the starting time should not be too long, and a proper interval should be left between each start.

working principle

The starting of the engine needs the support of external force, and the car starter is playing this role. Generally speaking, the starter uses three parts to realize the whole starting process. The DC motor introduces the current from the battery and causes the drive gear of the starter to produce mechanical movement; the transmission mechanism engages the drive gear into the flywheel ring gear, and at the same time can automatically disengage after the engine is started; the starter circuit is turned on and off by an electromagnetic switch to control. Among them, the electric motor is the main part inside the starter.

The process in which the engine transitions from a static state to self-running with the help of external force is called engine starting. The commonly used starting methods of the engine include manual starting, auxiliary gasoline engine starting and electric starting. It is simple but inconvenient and labor-intensive. It is only suitable for some low-power engines, and it is only reserved as a backup method in some cars; auxiliary gasoline engine starting is mainly used in high-power engines. On the diesel engine; the electric starting method is easy to operate, starts quickly, has the ability to start repeatedly, and can be controlled remotely, so it is widely used by modern vehicles.
