I saw a car spontaneously combust today, or a fuel car, why did the car spontaneously combust on such a cold day? I checked the reasons and summarized them as follows: There are many reasons for spontaneous combustion of automobiles, and the common ones include:
There are problems with the oil circuit of the car, such as oil leakage, liquid leakage, etc.
Deterioration or improper connection of vehicle wiring can lead to short circuits or sparks.
The high temperature causes the combustion of flammable materials, such as lighters, fresheners and other flammable and explosive materials in the car.
Fire caused by vehicle impact or mechanical failure.
Excessive accumulation of engine sludge can lead to spontaneous combustion at high temperatures.
When the engine is working, due to the high temperature of the ignition coil, the insulation layer of the high-voltage ignition wire is softened, aged and cracked, resulting in high-voltage electric leakage, which causes the temperature of the leakage to continue to rise, igniting the leakage gasoline of the engine and carburetor, and finally leading to ignition.
In spontaneous combustion accidents caused by line failures, iron lapping is the main cause. In particular, after the vehicle is equipped with anti-theft devices, high-end audio and other equipment, it may cause the wires to catch the iron, which may cause the vehicle to spontaneously combust.
The line contact is not real, and the local resistance is too large, which will generate heat energy, which will heat the wire contact and cause combustible materials**.
Vaporizer tempering of motor vehicles, when the vehicle is in the driving state or when starting, the phenomenon of vaporizer tempering sometimes occurs, which can also lead to spontaneous combustion.
To prevent spontaneous combustion of automobiles, you can regularly check the electrical and oil circuits, do not place flammable and explosive materials on the dashboard, equip fire extinguishers, and clean up engine sludge before the arrival of summer. At the same time, do not easily modify the car without permission, so as not to cause safety problems.
