Matters needing attention of automobile spontaneous combustion in high temperature weather in summer
High temperature weather in summer is the high incidence of auto-ignition, and many car owners will maintain and maintain their cars in advance. At the same time, it is best not to drive for too long in hot weather, which is easy to spontaneously ignite.
Under normal circumstances, the car will smoke first and then burn. If the owner is alert at ordinary times, it is possible to avoid the fire by stopping early to check whether he smells abnormal smell. Therefore, the rider can check what is wrong with the car by smelling the abnormal smell.
A car consists of at least 7000 parts, including metal, plastic and rubber. When it is not properly worn and eaten, it will give off a pungent smell, such as burnt smell, bad smell, plastic smell and so on. According to these smells, we can judge some faults of the car with our noses.
Rubber smell
This smell is the easiest to distinguish. Check the belts, brake shoes and tires first to see if the rubber products in these parts are loose, slippery and overheated. If you find that the brakes or tires smell, please stop the engine immediately and wait until the heat dissipates before driving.
Plastic odor
This situation is mostly caused by overheating of the wire, because the plastic outer sheath of the wire is relatively thin and the smell is not very strong. However, when the conductor is short-circuited, it is often accompanied by local smoke or fever. After a long time, it is easy to cause burning and fire.
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. Under normal circumstances, there will be more cases where the wire temperature is too high in summer. If not found in time, it is easy to cause complete circuit damage, engine cylinder pulling, and even vehicle spontaneous combustion.
A strong burning smell
If you smell the special smell of non-metallic materials burning while driving, it is generally caused by the combustion or overheating of clutch friction plates. This smell will be mixed with the smell of burning, because the clutch plate is made of rubber, asbestos and other materials.
If the clutch is used normally, there is no obvious difficulty in shifting gears or starting, and the smell of the rear comes from the car, then it is necessary to check whether the rear brake system is overheated. Some careless car owners will lock the rear brake pads when driving hard, resulting in burning smell.
The smell of unburned gasoline.
If you can always smell unburned gasoline in the carriage, it should attract the attention of riders. Determine the location and degree of oil leakage before driving on the road.
When the vehicle is used for a long time, the oil pipe will age and crack, and fuel will leak from these parts. Therefore, when cyclists smell gasoline, they should immediately stop the engine, put out open flames such as cigarettes, and thoroughly check the oil pipeline. If the oil tank leaks, there is an emergency plan, that is, plug the oil spill with chewed gum and send it to repair as soon as possible. The smell of engine oil
This smell is common in carburetor cars, commonly known as "burning oil". In addition to the choking smell, the exhaust pipe will emit black smoke. One case is that the inner wall of the cylinder is seriously worn or the piston is seriously worn, and the engine oil rushes into the combustion chamber. On the other hand, the valve is seriously worn and may burn oil; There is also the aging of the vehicle oil pipe, and the oil drips on the engine or exhaust pipe, which will also give off an unpleasant smell at high temperature.
Battery odor
This situation is mostly caused by the leakage or loss of electrolyte, which mostly occurs in wet batteries, because such batteries need electrolyte to complete the storage and conversion of electric energy, but when the electrolyte leaks, it will produce a pungent smell. At the same time, if the electrolyte is consumed too much or at a loss, the automobile generator will forcibly charge the battery, which will cause the battery to overheat, emit white smoke and smell worse. If this problem is found, the electrolyte should be replenished in time to charge the battery.
Automobile spontaneous combustion needs to be discovered and solved as soon as possible, especially in the sultry summer. Safe travel is very important. It's best to check all aspects of car safety before driving. And when the weather is hot, the car should also cool down and rest. In addition, Bian Xiao reminded all car owners that it is best to equip their cars with fire extinguishers. Once a fire breaks out, it can be put out quickly to minimize losses.
In hot weather, not only should we pay attention to the maintenance of the car, but the owner should also control his driving skills and driving time to avoid the spontaneous combustion of the car due to long driving time. Besides, don't add too much gasoline.
In summer, high temperature and rain often lead to traffic accidents.
It's hot and rainy in summer, which is a season prone to traffic accidents. How to ensure driving safety in summer? The reporter interviewed Xiao Weiming, head of the accident section of Beijing Public Security Traffic Management Bureau. Combined with the characteristics of previous accidents, Xiao Kechang told reporters some precautions for driving safety in summer. It is easy to puncture at high temperature. Improper handling will lead to accidents.
Last summer, when a car was driving on the Beijing-Shijiazhuang Expressway, it suddenly had a flat tire. Improper handling by the driver caused the vehicle to roll over, the vehicle was scrapped and the driver was seriously injured. After the accident, after checking the tire pressure, it was found that it was over-inflated, and driving at high speed for a long time led to a flat tire.
When the temperature is high in summer, the pavement temperature is often higher than the air temperature. If you drive at high speed for a long time, the air pressure in the fetus will rise rapidly with the increase of temperature, which is easy to cause a puncture.
Tip: In order to ensure safety, vehicle tires must be inflated under standard air pressure. If the tire pressure is low, it will increase the contact between the tire and the road surface, and the possibility of puncture will increase; If the air pressure is too high, it will be affected by the principle of thermal expansion and contraction, and there will be a puncture, so it must be inflated according to the standard air pressure.
Slippery roads are prone to accidents in rainy days.
Summer is a rainy season. Rainy days have a great influence on safe driving.
Because the field of vision is not clear in rainy days, it will have a certain impact on safe driving; On rainy days, especially light rain, the rain and dust on the ground are mixed together, and the road surface is flat and the friction coefficient is reduced, which will also affect the driving safety. Under normal circumstances, the friction coefficient of pavement is about 0.7, while it is only about 0.4 in light rain. When braking, the vehicle is prone to sideslip and deviation, causing accidents. In addition, when it rains, the raincoat worn by the cyclist will affect the cyclist's line of sight, increase the blind spot of the cyclist's line of sight, and sometimes he can't see the car coming behind, which may also cause traffic accidents.
Tip: when driving in rainy days, you should slow down to prevent the front car from suddenly braking and it is too late to take measures; When driving, drive in the designated lane, and don't merge the front and rear lines; Do not slam on the brakes under any circumstances to prevent the vehicle from slipping out of control; Check the vehicle before leaving the vehicle to ensure that the wiper and other components are sensitive and effective; Driving in rainy days, especially in heavy rain and rainstorm, turn on the front and rear fog lights; When there is water on the road, you'd better find out the depth before you pass. Pay special attention to landslides when driving on mountain roads in rainy days.
Lack of sleep can lead to accidents.
Due to the high temperature in summer, sleep is seriously affected. Drivers are prone to drowsiness while driving, which leads to accidents. In order to ensure driving safety, especially drivers who run long distances, they must keep enough sleep.
Tip: If you feel sleepy while driving, please pull over and have a rest before driving.
Doing other actions that affect driving while driving can easily lead to accidents.
Due to the hot weather in summer, drivers often drink water, eat popsicles, smoke and other behaviors that affect safe driving.
These behaviors are not only illegal, but also have great safety hazards in driving. Doing these things while driving will distract the driver, and it is too late to take measures in case of emergency, leading to accidents.
Tip: Try to do less other things while driving, concentrate on driving and try not to chat with fellow passengers, especially novices.
Here, I especially want to remind my female friends who often drive. Never wear sandals and slippers, high heels or platform shoes without shoelaces when driving. Wearing these shoes will make it very inconvenient for you to step on the brakes and accelerator, and it will also cause danger because you can't step on the brakes or in an emergency. If it is necessary for work, you must wear high heels. You can put a pair of flat shoes in the car and wear them while driving.
Driving at night, pay attention to people enjoying the cool by the roadside.
In hot summer, many people come out to enjoy the cool at night, many people sit directly on the roadside or on the isolation belt, and many children will run around.
Pedestrians are very mobile and can stand up or walk at any time, especially children. Coupled with the poor sight at night, it is not easy for drivers to find these situations in time.
Tip: try not to drive too close to the sidewalk or isolation belt at night, and be sure to control the speed, especially on narrow roads or sections with many pedestrians; Rational use of lighting; Concentrate on observing the road conditions.
Summer is also a busy farming season. Occasionally, on some suburban roads, some farmers will hit a piece of land on the road to dry their grain. Drivers must be careful when driving to this section. First, crop straws become slippery after being crushed by passing vehicles; Second, some grain keepers or children will lie on the straw beside the road to rest. So drivers must pay attention to the road conditions and drive slowly. Last year, in a rural area, a truck ran over a child lying under wheat straw.
