More than 200 Ferrari sports cars spontaneously ignited on the streets of Dongyang. Under what circumstances will the car spontaneously ignite?

Vehicle spontaneous combustion generally has a process, which may have a burnt smell or black smoke at first. When the driver sees the dragged blue or black smoke from the window and rearview mirror, he should stop immediately, turn off the power supply, and then take out the fire extinguisher to put out the fire. Many car fires can be put out at an early stage. Therefore, the owner needs to know the storage location and use method of the fire extinguisher in the car. You'd better put one in the trunk and one in the car, just in case. Moreover, it may also cause spontaneous combustion because of the sudden difficulty in starting the vehicle or the obvious increase in jitter during driving, and the sudden increase in fuel consumption of the vehicle.

The first gasoline to leak is the most terrible combustible. Once the fuel leaks and the mixture reaches a certain concentration, if there is an open flame, the spontaneous combustion accident is inevitable. When the temperature is high in summer, the connecting oil pipe of the gasoline filter is deformed by heat, which makes the tightly connected hose loose when the temperature is low, which is the reason of gasoline leakage. Plastic smells, mostly caused by overheating of wires. Because the plastic coating of the wire is thin, the smell is not very strong. However, when the conductor is short-circuited, it is often accompanied by local smoke or fever, which is easy to cause burns and fires after a long time.

Once the wire is found to be overheated, it must be stopped immediately to find out the reason. Although the smell of wire burning is not big, the risk index is high. Generally speaking, there are many cases where the wire temperature is too high in summer. If not found in time, the circuit is easy to be completely damaged, and the engine cylinder is also prone to spontaneous combustion of the whole vehicle. When the car is tanned by the sun, air freshener, gas lighter, etc. It is easy to expand when heated, and may explode or explode, and the car will spontaneously ignite. Therefore, when the owner places these inflammable and explosive articles, it is best to put them on the dashboard, backboard, trunk and other positions. Avoid direct sunlight.

Electric leakage is also the cause. When the automobile engine is working, the temperature of the ignition coil is very high, and the insulation layer of the high-voltage ignition wire softens, ages and cracks. The ignition high-voltage electricity is easy to break through the insulation layer to produce high-voltage electricity leakage, which leads to the temperature rise of the leakage, igniting the gasoline leaked from the engine and carburetor, and leading to ignition and combustion. Modify. Many car owners like to install modified circuits such as headlights, stereos and anti-theft locks, which will definitely change the circuit or oil circuit of the vehicle and increase hidden dangers. Mechanical friction heating. The lack of lubricating oil in automobile engines will lead to high temperature caused by friction. If it comes into contact with objects that are still in use, it may lead to spontaneous combustion. Long service life of vehicles and aging lines.

Autoignition flammable items include lighters, perfumes, detergents, etc. Is placed in a vehicle. Pay attention to regular maintenance and self-inspection in daily life, don't put flammable items in the car, and try not to modify the vehicle lines to reduce the occurrence of spontaneous combustion.
