11 cars spontaneously combusted in 5 days, what caused the spontaneous combustion of cars? How to av

1. Short circuit caused by vehicle aging.

In the engine compartment of the car has dense circuits and electronic components all over it, with the increase of vehicle age, the engine compartment has been in a state of high temperature and high heat for a long time, and it is inevitable that the material outside the line will fall off in the long run, which will cause short circuit and leakage of the line in the car, and finally lead to the occurrence of open flames. In addition to the aging of the circuit, the aging of the oil circuit is more dangerous, due to the use of the vehicle in the summer high temperature, the engine compartment temperature in the car is higher than usual, plus some turbine vehicles can reach 800 degrees of temperature, once there is an oil leak The consequences are unimaginable.

2. Miscellaneous items are placed in the car.

For some men who have a habit of smoking, sometimes they will put the lighter in the car after lighting a cigarette. And some ladies also have perfume and other items in the car. In the summer, the temperature in the cabin can reach up to 90 degrees Celsius, and the direct sunlight is likely to detonate the fire.

In addition to this, there is a similar danger of keeping some mineral water bottles in the car, and we all learned that convex lenses can ignite black paper when we were students. In the same way, if the interior of the car is black and the refraction and reflection of water on the seats, it is very easy to ignite the interior.

3. The parking area is not up to standard.

Some car owners who go to the wild always like to park their cars under trees or in the shade, after all, it is good to enjoy the shade under the big trees, but sometimes they ignore the fact that the vehicle is parked near some dry turf, because the vehicle continues to maintain a high temperature state of heat dissipation after driving. If it encounters a dry environment, it is likely to reach the ignition point. Therefore, I also tell everyone to try to standardize parking when parking to avoid unnecessary trouble.

4. Battery quality problems and inadequate maintenance.

Nowadays, there are a variety of new energy vehicles on the domestic market, but some early technologies are not mature, and some car dealers in order to reduce costs do not inspect the vehicles themselves. In addition, the hot weather is that the battery will thermally runaway, many of which are due to the aging of the battery and therefore generate too much heat, plus the battery is used too frequently, so the battery is punctured separator and the internal short circuit.

5. Short circuit of the line caused by later modification.

In addition to the modification of the shape of the vehicle, many vehicles will choose to modify the high-power audio or decorate the interior and exterior of the body with many colorful and beautiful marquee lights or ambient lights. Such a post-modification is not only more individualized, but also some auto repair shops outside are cheaper than the original configuration or 4S shop installation, but the technology is worrying, and it may lead to a short circuit inside the vehicle line afterwards.

Do not put "dangerous" items in the car. Especially plastic or metal pressure canisters filled with flammable gases, such as lighters, air fresheners, hairsprays, etc. It should not be placed on the driver's platform of a motor vehicle at a high temperature in summer, so that the gas in the pressure vessel is easy to expand under the high temperature generated by sun exposure, thus causing combustion.

Equipped with firefighting equipment. Motor vehicles should be equipped with on-board fire extinguishers and be familiar with their use. At the same time, it should be noted that fire extinguishers have an expiration date and should be updated regularly.

In addition, it is best to have a basin or bucket in the back of the car in case you need it. **Among the spontaneous combustion accidents caused by road faults, the grip accidents caused by grounding account for a large part. Common line faults are:

The outer skin between the cable and the frame and wire clamp is damaged due to vibration friction, the outer skin of the tail lamp and brake light wires is damaged due to vibration friction, and the insulating parts at the lamp head installation are loose and damaged due to vibration and connector damage, etc. When these faults occur, the vehicle will trip for a long time due to the agitation of its own grounding when driving or stopping, resulting in damage to the insulation or sheath of electrical equipment, switches, and wires, thereby expanding the trip range and high temperature area. Sparks can catch fire if they come into contact with paint, leaking gasoline, etc.

The car start switch is welded due to contact sintering, and the magnetic switch of the starter cannot be released, which will cause the starter to start for a long time, resulting in heating**. After the car is turned off, the ammeter pointer should return to the zero position, but the reverse current circuit breaker contact of the engine regulator is still closed, causing the battery current to flow back to the generator and causing a disaster. Tires can also cause spontaneous combustion.

According to the principle of thermal expansion and cold contraction, in summer, the tires of the vehicle will burst due to high temperature inflation and bright skin trembling. During the driving of the vehicle, the puncture tire will be caused by friction with the ground and adjacent tires**, resulting in spontaneous combustion of the body. Most of the tires that burst and spontaneously combust are trucks.

Because the truck runs on the road for a long time, the tires run under high load, and some trucks are overloaded, so the tire pressure is too great, making the car very dangerous. Every time you wash your car, you should also clean up the dust and oil stains in the engine compartment. If necessary, you should go to a repair shop for professional cleaning.

It is also important to identify and eliminate some risks in a timely manner. Looking at the ** above, the temperature of some parts of the engine compartment is still very high. If the combustibles in the engine compartment cannot be cleaned up in time, it can easily ignite and cause spontaneous combustion.

Millions of car purchase subsidies.

Some roads will have flammable materials such as hay, and there is a high risk of getting entangled in the chassis of the car when passing through these roadsIt is well known that the temperature of the exhaust pipe of a car is abnormally high during driving, so the temperature of the exhaust pipe is enough to ignite these flammable substances. These "oils" are well considered in the design and manufacture of automobiles, and are transported by special closed pipelines. Under normal conditions, it will not escape from the closed pipeline.

Once it escapes from the closed pipeline, it can cause combustion when it reaches the ignition point in the non-closed state, causing spontaneous combustion of the car.

When the ignition high-voltage electricity breaks through the insulation layer, it is easy to produce high-voltage electric leakage, which causes the temperature of the leakage to continue to rise, which will ignite the engine, carburetor and other leaking gasoline, which will lead to ignition. Generally, the line of the car should be checked once a year to ensure that the line is not broken and short-circuited; If the engine is found to be high temperature, it should be cleaned and repaired in time; Learn more about the vehicle and identify risk points. When the heat generation of the battery system exceeds its own cooling capacity, it will lead to combustion, but if the BMS of the battery itself does a good job in energy management, there will be no combustion, and the BMS will reduce or disconnect the circuit according to the heating situation of the battery system, or start the liquid cooling system to speed up the cooling effect.

Spontaneous combustion of the vehicle will not only cause damage to the owner's property, but also endanger the owner's life. Therefore, you must do regular maintenance, open the hood regularly to check for oil leakage and other abnormalities, and clean up the debris (leaves, weeds, etc.) in the engine compartment to avoid unnecessary losses.

When the heat generation of the battery system exceeds its own cooling capacity, it will lead to combustion, but if the BMS of the battery itself does a good job in energy management, there will be no combustion, and the BMS will reduce or disconnect the circuit according to the heating situation of the battery system, or start the liquid cooling system to speed up the cooling effect.

The main ones are as follows: first, it is not maintained for a long time, and the line is aging; the second is oil leakage; third, caused by external fire sources; Driving for a long time in high temperature conditions, encountering some flammable materials; Fourth, some assembly errors or design defects at the factory.

Spontaneous combustion of automobiles is mainly affected by high temperatures and impacts, because violent impacts cause damage to the vehicle's fuel tank, fuel leakage, and high temperatures, which cause nature.

Short circuits caused by the aging of vehicles.

With the increase of vehicle age, the engine compartment is in a state of high temperature and high heat for a long time, and in the long run, it is inevitable that the material outside the line will fall off and cause short circuit and leakage in the car, and finally lead to spontaneous combustion caused by open flame.

In the vehicle often put some small objects, lighter perfume, these will cause the vehicle to spontaneous combustion, and because the temperature in summer is very high, it will also lead to spontaneous combustion, very dangerous, it is best not to.

The reasons for the spontaneous combustion of the car: 1. There is a problem with the oil circuit of the car, resulting in oil leakage and liquid leakage. 2. It is the aging of the vehicle wires or improper connection that causes short circuit or sparks.

3. It is the combustion of flammable materials caused by high temperature. 4. It is caused by a vehicle impact or a failure of a mechanical part. 5. Excessive accumulation of engine sludge, high temperature in summer and high temperature of the engine, resulting in spontaneous combustion of oil sludge due to high temperature.

The causes of spontaneous combustion of automobiles include fuel leakage, electricity leakage, short circuit or aging of wires and circuits, combustibles placed in the car, and inferior modifications. A vehicle that spontaneously combusts is a loss caused by the natural cause of a motor vehicle, and its registration may be cancelled in accordance with the provisions of the Measures of the People's Republic of China for the Registration of Motor Vehicles.

1. Fuel leakage of automobiles due to fuel leakage caused by spontaneous combustion of automobiles is a more typical one, once the fuel leaks, the mixture reaches a certain concentration, and if there is an open flame, spontaneous combustion accidents are inevitable. The cause of gasoline leakage often occurs in summer, because the temperature is high, the connecting oil pipe of the gasoline filter is deformed due to heating, which makes the hose that was tightly connected when the temperature is low and loosens the heat, resulting in fuel leakage.

2. When the automobile leakage engine is working, the temperature of the ignition coil is very high, which softens, ages and cracks the insulation layer of the high-voltage ignition wire, and the ignition high-voltage electricity is easy to break through the insulation layer, so that the high-voltage electric leakage will cause the temperature of the leakage to continue to rise, igniting the leakage gasoline of the engine carburetor and other leaks, resulting in ignition.

3. The common electrical short circuit caused by the short circuit or aging of wires and circuits is that the starter switch is welded due to contact sintering, and the starter magnetic switch cannot be released, resulting in the starter starting for a long time, so that the engine heats up and spontaneously combusts. The aging of the circuit is also a major cause of spontaneous combustion of automobiles, and the aging of the rubber covering the wire leads to the exposure of the inner core, which is easy to produce sparks and spontaneous combustion.

Fourth, the spontaneous combustion caused by the placement of items in the car Some people will use some spherical decorations made of glass in the car, which is very beautiful, but this glass product will produce a concentrating effect when it is irradiated by the sun, similar to the principle of the convex lens, the focus of the concentrating light will produce high temperature, and if there is a combustible, it will be ignited, thus causing spontaneous combustion of the car. There are also combustible substances such as lighters, perfumes, and air fresheners placed in the car, which will volatilize under the action of high temperature in the car, and if it reaches a certain concentration, it will burn or ** when it encounters sparks.

Fifth, due to the spontaneous combustion caused by inferior modifications, many car owners like to modify their cars, add anti-theft devices to the vehicle, replace high-end audio, transform type, add air conditioning and so on. Due to the non-professional wiring and plugging during the installation process, the circuit is easy to short circuit during use, which buries potential safety hazards for the spontaneous combustion of the vehicle.
