How to prevent auto-ignition?

How to prevent auto-ignition? Today, we are going to talk to you about the causes of auto-ignition. What we usually do may cause spontaneous combustion. What measures can be taken to prevent these things when using the car at ordinary times? Take a look with your favorite friends. The temperature rises in hot summer, which is also the harvest season of some crops (rice, wheat, sugar cane), and it is easy to cause spontaneous combustion of vehicles during this period. Most of these fires are caused by drivers parking their vehicles or driving them on the road covered with flammable straws, wheat straws and sugarcane leaves. The high temperature of the exhaust pipe of the vehicle will contact the straws, wheat straws and sugarcane leaves under the vehicle and ignite them, which will lead to the fire of the vehicle.

Don't put "dangerous" items in the car. Especially plastic or metal pressure tanks filled with flammable gases, such as lighters, air fresheners, hair gel, etc. It should not be placed on the driving platform of motor vehicles under high temperature in summer, which will easily make the gas in the pressure vessel expand under the high temperature generated by sun exposure, thus causing explosion and combustion. Equipped with fire fighting 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 a shelf life and should be updated regularly. In addition, it is best to prepare a basin or bucket at the back of the car in case of emergency.

In the spontaneous combustion accident caused by line fault, grounding accounts for a large part. Common line faults include: skin breakage between cable and frame and clamp due to vibration and friction, skin breakage of tail lamp and brake lamp lead due to vibration and friction, and insulation looseness and damage at lamp holder installation due to vibration and joint fracture. When these faults occur, the vehicle will catch fire for a long time due to self-grounding when driving or parking, which will damage the insulation layer or sheath of electrical equipment, switches and wires, and then expand the fire-jumping range and high temperature area. Sparks will catch fire if they come into contact with paint, leaking gasoline, etc.

The automobile starting switch is fused and 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 and cause heat and fire. After the car is turned off, the ammeter pointer should return to zero, but because the contact of the reverse current circuit breaker of the engine regulator is still closed, the battery current flows back to the generator, causing a fire. Tires can also cause "spontaneous combustion". "According to the principle of thermal expansion and cold contraction, vehicle tires will burst due to high temperature' flatulence' in summer. During the driving of the vehicle, the burst tire will rub against the ground and adjacent tires and catch fire, resulting in spontaneous combustion of the vehicle body. " Most of the spontaneous combustion caused by puncture is caused by trucks. Because trucks run on the road for a long time, the tires run at high load, and some trucks are overloaded, so the tires are overloaded, which will make the car very dangerous.

Some car owners like to wear sunglasses to drive in summer. Wearing sunglasses can block the dazzling light, but some sunglasses have strong ability to block the light, which is very dangerous when looking down or looking elsewhere. Cool mats are standard for many car owners in summer, but some car owners just put them on their seats for convenience, which is very dangerous. During emergency braking, the driver will slide forward with a cold pad under the action of inertia, which is very dangerous. Among the causes of spontaneous combustion accidents, the oil circuit is as important and terrible as the hidden danger of the circuit. Because part of the oil leakage in the engine room was not found in time, the engine room temperature rose sharply in the high temperature environment in summer, which was enough to ignite the oil leakage and caused the danger of spontaneous combustion. Many car owners often clean the appearance of their cars, but they seem to be too negligent in cleaning the carriages. The paint on the outside of the car is bright, but the dust inside the car is thick, which not only affects the appearance, but also makes it difficult to find potential safety hazards.

Therefore, it is also very important to clean up the dust and oil stains in the engine compartment every time you wash the car. If necessary, go to the repair shop for professional cleaning to find and eliminate some risks in time. Look at the table above. The temperature of some parts in the generator cabin is still very high. If the combustible materials in the engine compartment cannot be cleaned in time, it is easy to ignite and cause spontaneous combustion.

Emergency treatment after spontaneous combustion: 1. Learn to prevent auto-ignition. Spontaneous combustion generally has early precursors, such as abnormal sound and odor in the body, which should be stopped immediately. It's best to park your car in a sheltered place. 2. Find the fire point and be careful not to open the front cover at will. Learn to prevent spontaneous combustion, because the air entering the car is easy to fuel combustion, so put the fire extinguisher in your hand before turning it on. 3. If the fire is out of control, call 1 19 immediately. Learn to prevent auto spontaneous combustion, and call the insured insurance company to report the case, get the report number at the first time, or ask the insurance company to be present. 4. After the fire brigade put out the fire, ask for a police officer's card and describe the cause of the fire. 5. Drag the car to the corresponding repair shop according to the requirements of the insurance company and notify the insurance company to determine the damage. Learn to prevent spontaneous combustion, generally about 80% in payout ratio.
