In the hot summer weather, spontaneous combustion of vehicles occurs due to oil circuit, circuit, etc., which often causes the vehicle to be scrapped and sometimes even endangers personal safety. In this regard, fire protection professionals propose that “in-cabin cleaning” can prevent spontaneous combustion and provide two key preventive measures.

A few days ago in front of China Merchants Bank’s sales office at Zhongshan Road, Heping District, Shenyang City, Liaoning Province, a black smoke ignited in the engine compartment of a silver-gray car and gradually spontaneously ignited. After the firefighters rushed to the scene, they reminded the owner to “do not open the car cover first” and finally helped to extinguish the fire, but the car was basically scrapped.

The reporter learned from the Shenyang City Fire Fighting Brigade that since May, the temperature has risen significantly and the number of spontaneous combustion vehicles has started to increase. In the past half a month, there have been 36 car fire accidents in the city, which is the highest in the calendar year. Most of the current auto-ignition incidents are caused by the short-circuit of electric wires under high-temperature weather, and the probability of their occurrence is more than 60%; followed by oil circuit problems. One of the recent changes is the increase in self-ignition caused by car decoration.

Sun Guofeng, a senior engineer of the Shenyang Fire Fighting Brigade, believes that there are two main incentives for auto-ignition of the vehicle. One is the short circuit caused by aging of the circuit. A large part of the auto-ignition accident is fire in the engine compartment. This is due to aging of the circuit or damage to the insulating rubber and the connector is virtual. Caused by the short circuit caused by fire. Another inducement is that the aging of the oil passage leads to fire. Because some oil seepage and oil leakage in the engine room have not been discovered in time, the temperature in the engine room rises sharply in the high temperature environment in the summer, enough to ignite the leaking oil and cause the risk of spontaneous combustion. "'Cabin cleaning' can prevent spontaneous combustion, causing short-circuit to the circuit's aging. The way to avoid it is to develop a good inspection habit. Regularly check some circuit circuits inside the car; while for the oil aging problem, the car wash is also at the same time To clean the engine compartment of dust and grease, if necessary, go to the repair shop for professional cleaning, timely detection and eliminate the risk." He suggested.
