How Does the Car Starting System Work?

[DelLogan]

The working principle of a car starting system is to convert the electrical energy from the battery into mechanical energy through the starter motor to initiate the engine operation. Below is an introduction to the car starting system: 1. Basic components of the starting system: It consists of the battery, ignition switch, starter relay, and starter motor. 2. Function of the starting system: It converts the battery's electrical energy into mechanical energy via the starter motor to start the engine. The starter switch activates the starter motor's electromagnetic switch circuit, allowing the electromagnetic switch to operate. In gasoline engines, the starter switch is integrated with the ignition switch. The starter relay controls the on/off state of the starter motor's electromagnetic switch circuit through its contacts (normally open type). The starter switch only controls the starter relay coil circuit, thereby protecting the starter switch. There are single-type relays (protecting the starter switch) and compound-type relays (protecting both the starter switch and the starter motor).
