What Are the Causes of Car Spontaneous Combustion?
2 Answers
Causes of spontaneous combustion are as follows: Short circuits caused by vehicle aging: The engine compartment of a car is densely packed with wires and electronic components. As the vehicle ages, the engine compartment remains in a high-temperature and high-heat state for extended periods. Over time, the outer materials of the wires may peel off, leading to short circuits and leakage in the vehicle's wiring, ultimately resulting in open flames and causing a fire. Clutter placed haphazardly inside the car: For men who have a smoking habit, they might casually leave lighters in the car after lighting a cigarette. Some women may also place items like perfume in the car. During summer, the temperature inside the car can reach up to 90 degrees, and combined with direct sunlight, this could potentially ignite the lighter, posing a danger. Parking in non-compliant areas: Parking near dry grass can be hazardous as the vehicle continues to dissipate high heat after driving.
From a technical perspective of automotive research, vehicle spontaneous combustion is mostly rooted in electrical system issues. Aging wires lead to short circuits, especially during hot seasons when insulation cracks and sparks fly; fuel line leaks are even worse, with gasoline dripping onto scorching exhaust manifolds and igniting instantly, causing major disasters. Aftermarket audio or lighting modifications that exceed power ratings can overload fuses, triggering chain reactions. Loose battery terminals generate arcs, easily spreading within the confined engine compartment. Mechanical failures like radiator blockages can also cause coolant temperatures to skyrocket, igniting nearby plastic components. It's recommended to regularly scan circuits with infrared thermal imagers to ensure safety. Prevention is key—never overlook early signs of minor wear and tear.
