The vehicle circuit usually consists of a starting circuit, a power supply circuit, a lighting and light signal device circuit, an ignition circuit, an auxiliary device circuit, an electronic control system circuit, and an instrument information system circuit.
The common faults of ignition coil are open circuits, short circuits, damage to electrical equipment, etc.
What are the reasons for the ignition system to catch fire?
Speaking of "natural", I believe everyone is familiar with it. In spontaneous combustion events, ignition coil fires account for a large proportion.
1. The circuit lines of lighting and electrical equipment are aging and the ignition coil load is too high
2. Modern automobiles have more and more electronic control technologies, and the application of automobile intelligence has greatly increased the corresponding power consumption of automobile electronics.
2. When the engine is working, the temperature of the ignition coil is very high, which is easy to soften, age, and crack the insulation layer of the high-voltage ignition wire, and the ignition high-voltage electricity is easy to breaks down the insulation layer and generate high voltage.
