The weather is very hot recently. How to prevent nature when driving?

It is necessary to install qualified heat insulation film on the windshield and window, and park the vehicle in the shade as far as possible to prevent the temperature inside the vehicle from being too high. Second, perfumes, lighters, sealed drinks and other flammable and explosive items can not be placed in the car, so as to avoid burning in direct sunlight and injuring the car. Third, we should pay attention to finding some abnormal use of cars, such as abnormal sound and burning smell. It is necessary to open the engine cover regularly for self-inspection. If you find too much oil on the line, please ask professionals to clean it up in time to eliminate the hidden danger of spontaneous combustion.

According to statistics, the auto-ignition parts of vehicles mainly include engines, dashboards and tires. According to different parts, we took different measures before the fire brigade arrived. The first is to equip with an effective fire extinguisher. In the case of Zhangjiagang, the taxi driver took out the fire extinguisher to save himself, but the fire extinguisher was ineffective and missed the best first 3 minutes. If the engine spontaneously ignites, the owner should open the engine cover at the first time and aim the fire extinguisher at the engine to put out the fire. Beware of high temperature burns in the car. If the fire is already very big, you should give up self-help and wait for rescue. If the dashboard spontaneously ignites and is still in the smoking stage, it may be caused by a short circuit of the wire. At this point, the circuit inside the car can no longer be cut off. Under the condition of ensuring their own safety, the owner can get off the car, open the hood, pull out the fuse and cut off the power manually to avoid the spread of the fire. If the tire spontaneously ignites, get off the car as soon as possible to put out the fire, and protect the fuel tank to prevent the fire from igniting the fuel tank. How to escape from a trapped car during spontaneous combustion

When a sealed car body is on fire and the door can't be opened from the inside, quickly wrap it with clothes, towels and other opponents, and then break the doors, windows or windshield from the car with fists, arms and other parts; Or use a small hammer, metal bar, metal kettle, car fire extinguisher, etc. You can remove the windows and doors at once. In addition, at present, many car luggage compartments have internal escape function, so we might as well learn about this function from now on. At the same time, avoid inhaling toxic gases. If you are trapped in a bus or near a burning vehicle, cover your nose and mouth with a towel or clothes after getting wet with water, then squat down, walk forward in small steps and evacuate to a safe area.

Spontaneous combustion, nothing more than two reasons-oil circuit and circuit problems.

1, oil circuit-fuel may leak after aging.

Fuel can be said to be a sufficient condition for spontaneous combustion. Because fuel is combustible, whether it is gasoline or diesel, as long as there is oxygen, it will burn as long as it meets an open flame. If this kind of combustion happens in the cylinder, it will bring power and torque to our car. If the fuel burns outside the cylinder, it will make the owner feel very uncomfortable. Why does fuel burn outside the cylinder? The main reason is that the vehicle maintenance is not in place at ordinary times, and the pipeline and some interfaces will age after experiencing the cold winter and heat. If we ignore this aging, we don't know when the fuel is slowly leaking, and it is very likely that spontaneous combustion will occur at some point.

2, the circuit-the open flame of the thread is the culprit.

Fuel will ignite when it meets an open flame, and the circuit system of the car itself is the easiest to ignite fuel (of course, other open flames are not excluded). Therefore, it is necessary to regularly check the circuit system of the car. Virtual connection, grounding, leakage and short circuit of wire connector will directly ignite. If we happen to encounter a leaking fuel at this time, it will burn.

★ preventive measures sharing

First, oil inspection

Editor's suggestion: In the early summer, especially after driving for more than 3 years, it is best to go to the 4S shop or professional maintenance center in the auto parts city for an oil circuit inspection, including whether the engine leaks oil, whether the chassis leaks oil, and whether the oil pipe shows signs of aging and cracking. If oil stains like the one below are attached to the engine or oil skin, you need to pay attention! These oil stains may be engine oil or fuel. If it is fuel, it may lead to a great hidden danger of spontaneous combustion.

If it is confirmed that the leaked oil stain is fuel, it is necessary to continue to check the fuel supply system, among which the more important original parts include the joint between the fuel nozzle and the pipeline. If the leaked collective position is found, it must be replaced in time! In addition, if it is oil leakage, it is best to check the sealing problem of the cylinder.

Second, the circuit inspection

Check the circuit. Cars over three years old should have their circuits checked before summer, especially the ignition system in the engine compartment. Because the temperature of the ignition coil will be very high after the engine is started. When the car is used for a period of time, the high temperature generated by this ignition coil will soften, age and crack the insulation layer of the high-voltage ignition wire, so that the insulation of the high-voltage ignition wire can not be guaranteed. In severe cases, high voltage leakage will occur. If you encounter leaked oil and gas, it will be "explosive".

If you need to modify the audio and lighting after buying a car, you should pay attention to buying it in a regular modification shop or auto parts city and ask professionals to install it. You should pay attention to the fact that all the threads are wrapped in insulating cloth, and there can be no exposed threads. Loose threads can also cause sparks and accidents.

Third, keep good driving habits.

Suggestion 1: Be careful not to let the engine run at high load for a long time in summer. Because of the temperature of many systems (intake, exhaust, etc.). )' s engine will be very high after racing, and the heat dissipation of the engine is not very good in very hot weather, so it is even more difficult for him to run the engine at high load. If the temperature is too high, it may lead to what we often call "boiling", that is, the antifreeze will boil. If the pipeline of the cooling system is not well maintained, it is likely to burst in the fragile pipeline, and the result is that the antifreeze leaks and the car can't run. Therefore, in hot summer weather, we should also drive as gently as possible to keep the car cool.

Recommendation 2: It is best to park on a clean (non-flammable) ground. The exhaust pipe under the automobile chassis is a high temperature component. When the car is working normally, the temperature of the exhaust pipe is very high, especially the position of the three-way catalyst. In addition, it is difficult to dissipate heat in summer. If you stop and idle in time after normal driving, the exhaust pipe temperature will reach 800 degrees Celsius or even higher. In order not to let this high-temperature exhaust pipe bring us trouble, you should also master some skills when parking. When the car is parked on the road with hay, paint or other combustible substances after normal driving in summer, the high temperature exhaust pipe may ignite these combustible substances. Although the mechanical filter of this accident is very small, it can be avoided. After all, it is not difficult to park your car on clean ground.

Suggestion 3: If you need long-distance running, you should also pay attention to getting off and having a rest after running for a while. In the service area of the expressway, people may have a rest, and the car can also take the opportunity to cool down, because the engine keeps running at high speed during the long-distance running.
