It's too hot in summer, and the car is very hot. What dangers are prone to occur?

It's too hot outside and the temperature is too high. It is easy to cause spontaneous combustion, but it usually leads to vehicle spare parts for the following reasons: Why is the weather too hot and the car will spontaneously ignite?

First: the hidden dangers of inferior car modification.

In the misfire accident caused by line fault, the main reason is "iron". This phenomenon is mainly caused by aging, overload, short circuit, poor contact or wear of the "components" of the line, which will produce very large heat. If the wire quality is not good enough, or exceeds the flammable and explosive materials, it is easy to cause a fire.

Second: automobile wires and electrical appliances are short-circuited.

The most common electrical short circuit in wire short circuit is that the solder of starter switch is melted due to contact sintering, and the starter electromagnetic switch cannot be released, which leads to the starter working for a long time and the starter is hot.

In addition, in some single-track cars, the damaged "iron" or electric "iron" of the live wire insulator will cause short circuit, especially in some long cars, the lines are left and arranged. The "protector" of car wires is a fuse. Once the wire is short-circuited, the fuse will blow quickly when a large current is generated. But for example, if the fuse is too big, some people can easily replace the standard fuse with copper wire, which may cause protection function, resulting in short circuit of the wire and fire.

Third: improper parking place.

Because the cars produced now are generally equipped with three-way catalytic reactors, and the temperature of the device in the exhaust pipe is very high, generally at 300℃ to 400℃, once there is combustible under the car, it is easy to be ignited by the three-way catalytic device, which leads to the spontaneous combustion of the car.

Lighters, perfumes and mousses in our daily life are also dangerous items that constitute car fires. If these items are placed on auto parts that are easily focused by the sun's rays, there is still a certain fire hazard. So check the inside of the car when you lock it. Don't leave these dangerous goods, let alone put dangerous oil products such as gasoline and diesel.

Fifth: the car leaks.

Why do cars spontaneously ignite in such hot weather? When the engine is working, the ignition coil temperature is very high, which will soften, age and crack the insulation layer of high voltage ignition wire. Ignition high-voltage electricity is easy to damage the insulation layer, and it is easy to produce high-voltage leakage, which leads to the rising temperature at the leakage place. Ignite the leaked gasoline from the engine, carburetor, etc. , causing burning and burning.

In addition to the above reasons, there are actually oil leakage, long-distance driving in hot weather and excessive contact resistance.
