high temperature warning attack. Drivers should not only do a good job in personal heatstroke prevention, but also pay attention to vehicle maintenance. Preventing spontaneous combustion is the key. How to prevent spontaneous combustion when driving? Here are ten tips to keep away from vehicle spontaneous combustion. Safe driving is the key!
prevention is the key. How to prevent spontaneous combustion during driving?
30 ℃, 32 ℃, 34 ℃, 35 ℃… Entering dog days, which also marks the hottest time of the year. However, such a temperature “Hurts” many citizens’ cars. The car boils down during driving, and the most terrible thing is that the car spontaneously ignites. Such news will appear in the major media every day.
there are two common causes of vehicle spontaneous combustion:
on the one hand, the wires in the vehicle body are exposed due to maintenance or installation of in vehicle configuration, resulting in short circuit and fire due to friction and damage during driving; On the other hand, there is oil leakage due to problems in the oil circuit. Once there is an electrostatic spark, it will often catch fire. Therefore, in summer, the driver should further check the vehicle circuit and oil circuit, and the vehicle must be equipped with fire-fighting tools in case.
1. Circuit inspection
check circuit. When you get on a car over three years old, you should check the circuit before the 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. After the vehicle has been used for a period of time, the high temperature generated by the ignition coil will soften, age and crack the insulation layer of the high-voltage ignition wire, so the insulation of the high-voltage ignition wire can not be guaranteed, and high-voltage electric leakage will occur in serious cases, If you encounter leaked oil and gas, it is “one touch and burn”.
2. Be alert to the peculiar smell in the car
if you smell the smell of rubber or see smoke in the edge gap of hood cover and near the instrument panel during driving, you should quickly pull over and turn off the engine, disconnect the main power switch of the whole car, check whether the fuel leaks and whether the water tank has no water, and you must not be careless. There is oil leakage in 2226700013 and 3337700012 vehicles, and the oil leakage is observed in time. In addition, a small number of vehicles also have spilled oil stains near the oil port, which bring hidden dangers to vehicle spontaneous combustion. When cleaning the vehicle, do not only pay attention to the appearance, but also focus on the maintenance / cleaning of the above places.
4. Self ignition prevention and refitting
the common automobile self ignition events are generally caused by the damage of oil circuit, circuit and automobile refitting parts, which has nothing to do with the old and new. Vehicles that have received non-standard maintenance or refitting will also have potential self ignition hazards. Some roadside shop workers are not professional enough. They do not analyze the vehicle line layout and specific structure before operation, do not consider the power of different lines and the capacitance of equipment, randomly lead wires, and do not add insurance in places with heavy load. These wrong operations will cause danger.
5. Refuse to smoke
many people will think that smoking on the truck is the most normal thing, but few people will take it as the cause of truck spontaneous combustion, but in fact, this is the most easily ignored point. Unquenched cigarette butts are an absolute safety hazard in the cab. Many truck drivers have the habit of smoking. After lighting cigarettes, they habitually throw the lighter on the central console. After a long time of sunshine exposure, the temperature rise in the car is easy to detonate the combustible gas in the lighter and cause a fire. Other perfumes placed on the central console contain flammable chemicals, which can easily become a time bomb for truck self ignition.
6. Do a good job in daily inspection
. Do not ignore the daily inspection of the vehicle. Pay attention to whether the connection and insulation of electrical equipment terminals and wires are reliable. Also check the tightness of fuel oil pipe, brake fluid pipe and power steering oil pipe. If leakage is found in these oil pipes, deal with it in time.
7. It is best to park on a clean (no combustibles) ground
. The exhaust pipe under the vehicle chassis is a high-temperature component. When the vehicle works normally, the temperature of the exhaust pipe is very high, especially the location of the three-way catalyst. In addition, it is difficult to dissipate heat in summer. Stop and idle after normal driving in time, The temperature of the exhaust pipe will reach 800 degrees Celsius or even higher. In order not to let the high-temperature exhaust pipe bring us trouble, we should also master some skills when parking. If you park the car on the road with hay, paint or other combustibles after normal driving, the high-temperature exhaust pipe may ignite these combustibles. Although the mechanical filter of this accident is very small, what can be avoided is to avoid it. After all, it is not difficult to park the car on a clean ground.
8. Maintain frequently and check more
. The gasoline filter element of some cars is near the high-voltage line. If the gasoline pipe is aged and not replaced in time, it is easy to be ignited by sparks. Many car owners have a misunderstanding about maintenance. They think that replacing the three filters is regular maintenance. In fact, regular maintenance also includes the inspection of braking system, steering system, gasoline pipeline, electrical circuit, etc.
9. Be familiar with the use of fire extinguishers
. Fire extinguishers are equipped with the vehicle. Generally speaking, about 2kg fire extinguishing devices can play an emergency fire extinguishing role. At present, many drivers just drive hard, do not maintain and repair the vehicle, and do not understand the vehicle condition. Once there is an accident on the road, it will be late. From the disposal of spontaneous combustion automobile accidents, some drivers simply don’t know how to put out the fire. They only know how to spray indiscriminately when they pick up the fire extinguisher, but they don’t know how to spray or which is the most effective. Some even can’t use the fire extinguisher. Therefore, the car is mainly familiar with the use of fire extinguishers to avoid being helpless in case of accidents.
10, “old cars” regular physical examination
“old cars” that have been driven for more than 5 years and cars that have had major accidents should be subject to regular comprehensive inspections such as line cleaning and troubleshooting to avoid accidents.
finally remind that car fires are often caused by small problems being ignored. Therefore, attention should be paid to parking. Don’t park near inflammables. Do not put inflammable goods such as gas lighters, air fresheners, perfume, mousse and so on in the car easily exposed to the sun’s rays, such as the instrument panel. Do not put gasoline, diesel and other dangerous oil products in the car. Routine inspection shall be carried out for the oil circuit for 1 ~ 2 times. If oil leakage is found, it must be repaired in time. When the car is driven in high temperature for a long time, you should have more rest on the way and don’t expose the car to the sun for a long time. In hot weather, you have to stop the engine for a short time. Equip the fire extinguisher on the vehicle as required, and remember to replace it regularly.
how to deal with emergency?
when burning smell or smoke is found, it should be understood that this is a precursor of spontaneous combustion. At this time, immediately pull the hand brake, turn off the power supply, quickly take out the fire extinguisher, cool the oil tank and burning part, and put out the fire to avoid explosion. Be careful not to open the front cover at will, because air entering the vehicle is easy to support combustion. If it is found late and the fire is large, stay away from the site as soon as possible, call 119 in time and contact the insurance company at the same time.
in case of vehicle spontaneous combustion, if the fire range is small, it can be covered with existing articles on the vehicle. If the fire area is large and there is no fire extinguisher, cover it with sand, ice and snow on the roadside, block passing vehicles and ask for fire extinguishing equipment. If the fire endangers the goods on the vehicle, the goods shall be quickly unloaded from the vehicle while putting out the fire. In any case, the fire and explosion prevention of the oil tank must be done well. If a car fire endangers the surrounding people or causes greater disasters, the car must drive to a safe area while extinguishing the fire.
