Why Do Cars Catch Fire Spontaneously?
2 Answers
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.
I’ve always found car fires quite terrifying. Common causes include electrical short circuits, especially in older cars with aging wiring or damage from animal chewing, where overheated wires can ignite. Fuel leaks are another major hazard—cracked fuel lines or loose connections can drip gasoline onto hot spots like the exhaust pipe, causing instant smoke. Battery issues, such as overcharging or corroded terminals, can also spark fires. Some enthusiasts modify their cars with added electronics, which may overload and overheat. I regularly inspect my car, clearing debris like oil stains or paper scraps from the engine bay to eliminate ignition sources. On hot days, I park in the shade and avoid shutting down in grassy areas—these steps significantly reduce risks. Regular maintenance of fuel lines and wiring is crucial.
