Excessive accumulation of engine sludge, high temperature in summer and high temperature of the engine, cause the sludge to spontaneously ignite due to high temperature.
The age of the vehicle is too high, the oil circuit is aging, the sludge is accumulated, and the heat dissipation is difficult, which is also an important reason for the spontaneous combustion of the vehicle.
Common external factors failure causes: cargo box fires, unextinguished shaking head blows back into the car, three-way catalytic converter ignites attachments, lighters, perfume deflagration, etc.
Inquiry, determine the fire area When entering the accident scene, the first thing to do is to determine the fire area, and then determine the overfire area (where the burning is the most serious), so as to judge the fire point.
