What is the main reason why cars will spontaneously ignite?

There are two main reasons for automobile spontaneous combustion. The first is caused by the design and aging of the vehicle itself. The second category is caused by the negligence of the owner. The design and aging of the vehicle itself are mainly caused by the aging of the circuit and oil circuit; Man-made, mainly due to the owner's inadequate maintenance and improper use of the vehicle. The engine compartment of an automobile is covered with various electronic components and wires, and the engine compartment is in a state of high temperature and high heat for a long time. In this environment, the wire sheath is prone to aging and damage. If the owner is negligent in inspection and maintenance, it is easy to leak electricity and short circuit, resulting in open fire in the engine compartment and spontaneous combustion of the vehicle. High temperature in summer is more likely to cause circuit aging, so many spontaneous combustion events will occur in summer. Oil aging is very prone to spontaneous combustion. Compared with circuit aging, oil circuit aging is more unsafe in summer. Because the car is exposed to high temperature, the heat generated by the operation of the engine and various components is high, which makes the temperature in the engine compartment higher; At present, many models are turbocharged, and the working temperature of the turbine is as high as 800 degrees Celsius. If the engine compartment is aging due to oil passage and oil leakage, the risk of vehicle spontaneous combustion is very high. Static electricity can cause fire. According to statistics, the proportion of accidents when women refuel is higher than that of men.

Because a high proportion of women are waiting in the cab when refueling, drivers return to their seats and rub them with electricity, which may cause fire when discharging. At the same time, due to some clothes, seat covers and other reasons, if the static electricity on the car accumulates to a certain extent, a fire will also occur. Pay attention to discharge at ordinary times, such as buying a discharge stick, choosing a seat cover or wearing pure cotton clothes. The bad habit of some car owners to place flammable materials at will may also cause car fires. As we all know, lighters, perfumes and mousse in our daily life are also dangerous goods that constitute car fires. If these items are placed in the parts of the car that are easily exposed to sunlight, there is also a certain fire hazard. Once other combustible parts in the car are ignited, the consequences are equally serious. Once a car owner put a lighter in his car. After high temperature baking, the lighter burns and ignites the car.
