How to properly protect the sealing performance of the car

 

In the hot summer weather, spontaneous combustion of vehicles caused by oil circuits and electrical circuits often occurs, which often causes the vehicles to be scrapped and sometimes even endangers personal safety. In this regard, fire protection professionals proposed that “cleaning in the cabin” can prevent spontaneous combustion, and specifically gave two key preventive measures.

A few days ago, in front of the business department of China Merchants Bank, Zhongshan Road, Heping District, Shenyang City, Liaoning Province, a black smoke suddenly appeared from the engine compartment of a silver-gray car, and then spontaneously ignited. After the firefighters rushed to the scene, they reminded the car owner to “don’t open the car cover yet”, and helped extinguish the fire, but the car was basically scrapped.

The reporter learned from the Shenyang Fire Brigade that since May, the temperature has risen significantly, and spontaneous combustion of vehicles has begun to increase. In just half a month, 36 car fire accidents have occurred in the city, which is the highest in the past year. At present, most common automobile spontaneous combustion incidents are caused by short circuits in high-temperature weather, and the probability of occurrence is more than 60%; the second is the oil circuit problem. A recent change is that spontaneous combustion incidents caused by car decoration have also begun to increase.

Sun Guofeng, a senior engineer of the Shenyang Fire Fighting Detachment, believes that there are two main causes of vehicle spontaneous combustion. One is the short circuit caused by the aging of the circuit. A large part of the spontaneous combustion accidents are caused by fire in the engine compartment. Connection, etc. caused by short circuit and fire. Another cause is the aging of the oil circuit leading to a fire. Because some oil leakage and oil leakage in the engine room have not been detected in time, the temperature in the engine room rises sharply in the summer high temperature environment, which is enough to ignite the leaking oil and cause the risk of spontaneous combustion. “‘Cabin cleaning’ can prevent spontaneous combustion. For short circuits caused by aging of the circuit, the way to avoid it is to develop a good inspection habit and regularly check some circuits in the car; and for the problem of aging oil circuits, wash the car at the same time. It is necessary to clean the dust and oil stains in the engine compartment, and if necessary, go to the repair shop for professional cleaning, so as to discover and eliminate the risks in time.” He suggested.
