Four major causes of vehicle fire

● Oil factors

Oil, the various oils in cars. Many car fires are ultimately caused by the ignited fuel in the car. In addition, oils such as engine oil and transmission oil are equally flammable. When these greases encounter high temperatures or open flames, they may be Ignition causes a fire. There are many factors that can cause oil leaks. Of course, the primary factor comes from traffic accidents. Whether in the movie or reality, there is often a picture of a fire after a fierce collision, and this is also true of the “22 May” traffic accident.

It is difficult to avoid fuel leakage in a severe impact accident. First of all, it is hoped that everyone can drive safely and reduce accidents. However, there are other factors that can lead to auto-ignition of the car caused by oil leakage. It is also worthy of our guard, including the The reason, as well as the cause of the oil.

One of the reasons for the car is due to the lack of maintenance of the vehicle for a long time, resulting in equipment aging and damage; another reason is the non-standard and unreasonable modification, resulting in oil line damage and seal problems; there is no use in the repair and maintenance Qualified accessories, these may cause oil leakage. The reason for the oil is that some of the oils are corrosive. Like ethanol gasoline and methanol gasoline, it is easy to cause corrosion on oil path plastic pads and rubber pads, causing oil leakage.

For the above reasons, we should be more concerned about the long-term care of vehicles, especially when the summer is approaching, we must strengthen the inspection of various oil routes during daily maintenance, and must be qualified The accessories for the modified parts involving fuel must be monitored and prevented before they occur.

● Electric factors

Electricity refers to the circuit of the car. Auto circuit fires account for a very high proportion of spontaneous combustion events. For some “older” vehicles, the softening, aging, and cracking of the insulation layer of the high-voltage ignition wire makes it possible for the ignition high voltage to break through the insulation layer, which can easily lead to spontaneous combustion due to short-circuiting due to high voltage leakage. Wear of other circuit insulation is easily connected with the metal material of the body or contact with other circuits to cause a short circuit and generate sparks.

Like the oil circuit, we also need to take it seriously for the circuit. Car lines often appear after a long time after the use of rubber aging, damage, increase the resistance of the wire and the phenomenon of heat, prone to short-circuit, need regular inspection; also check to check the battery terminals because of impurities, oil or corrosion makes the contact loose heat , Or the long-term impact of vibration or sudden changes in temperature and make the line contacts loose phenomenon. In addition, do not easily self-modify the car, if it must be modified, professional and technical personnel should be professionally modified, the source must be wrapped to prevent leakage.

If you inspected your vehicle according to the above “oil” and “electricity”, then it means that your car has already achieved basic safety from the hardware, but the following external factors are equally important.

● foreign body factors

Foreign objects refer to flammable foreign objects from outside the vehicle. We all know that after long-distance driving, the temperature of the car's engine, catalytic converter, engine exhaust, etc. is very high. In the summer when the ground temperature is high, the maximum temperature of the exhaust portion of the under-engine engine can be higher than during idle. At 800 degrees Celsius, if there is hay, paint, or other flammable materials on the parking floor, it may ignite under prolonged baking, thus igniting the car. When parking, you should also have “more eyes”, and look at the flammable objects under the engine. Otherwise, even if the engine is off, there are still hidden dangers that these items are ignited by the excess temperature to ignite the vehicle.

In addition, under the summer sun's simmering, the vehicle's temperature inside the vehicle can reach 60 degrees Celsius, the flammable and explosive items in the vehicle can become very dangerous, and it is easy to become the culprit of spontaneous combustion. For example, the lighter placed on the center console is likely to explode due to the gasification of liquid butane due to high temperatures. The perfume used in the car contains volatile alcohol. The alcohol in the vehicle will continuously evaporate during exposure and the resulting alcohol vapor will fluctuate. The air is mixed as a combustible gas mixture. This combustible gas mixture can “flash fire” at a lower temperature (this temperature is called a flash point) and is likely to ignite other items in the vehicle. Many car interior materials are not yet fire-resistant. In the event of a fire, the fire can easily spread. In addition, reading glasses or magnifiers, which are placed near the windshield, are also very dangerous items. They have the effect of concentrating light. They can gather light that enters the windshield, and they can generate a high temperature of 100 degrees Celsius at the focal point. Interior parts of the car cause fire.

When approaching summer, be sure to check the contents of the car. Try not to put items that are likely to cause hidden dangers in the car. Try to avoid prolonged exposure during parking. If possible, you can choose to stop at the basement or for yourself. The car prepares a set of shades, which can not only maintain a low temperature inside the car and improve safety, but also help prevent premature aging of the interior of the vehicle under exposure and extend the life of the interior trim. The luggage compartment also needs to be “cleaned up”. Many owners like to prepare some oil in the luggage compartment. For owners who often park their cars in the open air in the summer, they need to be careful because once the vehicle is spontaneously combusted, these oils will play “fire”. Pouring role. In addition, various types of cleaners used in cars do not fit in the luggage compartment in the summer. They are all flammable items.

If you have done a good job of checking the above three categories of fire incentives, then I believe that your car has ruled out most of the fire hazards, the next content to be introduced is not the owner can control, but it requires you to pay special attention to related According to the news, it is necessary to take timely action on the content related to the car.

●Hazard due to design and assembly defects

Things in the world are flawed, and so are cars. What's more, cars are also manufactured by imperfect human designs. Some of the flaws in some vehicles are also the cause of car fires. This kind of hidden danger is usually that ordinary consumers can't find and check out on their own. This requires you to pay due attention to relevant news about car recalls. The easiest way is to look at car homes frequently. We will pay attention to and report all car defects. Recall information. Below, we will list some cases of fire that have occurred because of defects in design and assembly. These cases have finally been resolved by manufacturers. The purpose of this case is to remind everyone that there are some abnormal phenomena that occur when using vehicles. Especially when smelling some burning odors, you must not take it lightly and communicate with repair shops and manufacturers as soon as possible.

to sum up:

Whenever we see a report that the vehicle is on fire, we worry about the people in the car on the one hand, and on the other hand, we are sorry for the vehicles devoured by the fire. Everyone does not want this kind of thing to happen to them. For the safety of themselves and their families, we must drive safely and civilly. In addition, it is recommended that you regularly check your vehicle in accordance with the aspects outlined in this article. Only by doing so, can you be able to prevent yourself from being involved in car fires and achieve the goal of safe driving.
