The hot summer has entered our lives, and the hot weather and high temperatures can leave safety hazards in many aspects. For example, when driving a car, like other fires, spontaneous combustion is also unpredictable. Therefore, if a car experiences spontaneous combustion, it will not only cause economic losses to the owner. According to professional maintenance personnel, car spontaneous combustion can be divided into three categories based on the different ignition points: engine compartment spontaneous combustion, carriage spontaneous combustion, and chassis system spontaneous combustion.
The causes of engine spontaneous combustion can be roughly divided into three categories: first, a short circuit in the wiring harness near the engine, poor contact, or unauthorized modification of the circuit causing the fire. 2、 Oil pipe leaks oil. 3、 The engine compartment is extremely dirty. For the above three types of reasons, to prevent engine self ignition, first of all, in addition to regular maintenance at a 4S store, it is best to conduct one to two comprehensive inspections of the body wiring harness and oil circuit at a repair station or reputable repair shop, and promptly replace aging or about to age pipelines and wiring harnesses. Secondly, either personally or at the repair shop, perform a cleaning operation on the engine compartment to ensure cleanliness. Once again, before driving, check if there are any water or oil stains under the car that has been parked all night. If so, it indicates that there is a leak in the car that needs to be repaired. Of course, it is normal for the air conditioning system to drip in summer. Finally, of course, do not use substandard car parts, including clutch parts, engine accessories, etc.
The reasons for spontaneous combustion in carriages can also be divided into three categories: firstly, the aging or poor contact of body wiring harnesses and fuses leads to short circuits leading to spontaneous combustion. Compared to the wiring harness in the engine compartment, due to the relatively clean environment of the carriage, there are relatively few cases of spontaneous combustion caused by short circuits in the body wiring. 2、 The spontaneous combustion caused by the explosion of flammable and explosive materials placed in the car (this situation is the most common). 3、 Burning caused by human smoking with cigarette butts not extinguished or thrown on car mats or carpets.
The chassis system's spontaneous combustion mainly refers to the tires. High ground temperatures in summer are one of the main causes of tire problems, especially for car tires that have been in use for a certain period of time, and their operation and wear conditions should be constantly monitored. Once a tire is found to be worn, the tread pattern becomes shallow, or the tire pressure is unstable, timely maintenance or replacement should be carried out.
