Why Do Cars Catch Fire Spontaneously?

[MelanieMarie]

Cars may catch fire spontaneously for the following reasons: 1. Electrical leakage: When the engine is running, the high temperature of the ignition coil can soften, age, or crack the insulation layer of the high-voltage ignition wires. This makes it easier for the high-voltage electricity to penetrate the insulation layer, leading to electrical leakage. The temperature at the leakage point continuously rises, igniting leaked gasoline from the engine or carburetor, ultimately causing a fire. 2. Grounding: Among self-ignition accidents caused by wiring faults, grounding is the primary cause. This is especially true for many new car owners who, out of affection for their newly purchased vehicles, install anti-theft devices, upgrade to high-end audio systems, or modify the car's appearance. These actions can potentially cause wiring to ground, leading to vehicle self-ignition.
