In the continuous high temperature weather, people and vehicles are subjected to the "roasting" test, and in the hot summer, we must beware of spontaneous combustion of vehicles.
At about 7 p.m. on July 22, a car spontaneously combusted downstairs in Building 4 of the Hanlin Square Community in the downtown area. Subsequently, firefighters rushed to extinguish the fire, and the fire did not further expand. Although the actual cause of the car fire has not yet been clarified. However, in hot weather, if the car has fuel tank leakage or aging wiring, it is easy to spontaneous combustion of the vehicle.
Yong Anfeng, technical manager of Bozhou Chery 4S store, suggested that in summer, the car owner should often check whether the vehicle engine has oil leakage, whether the oil pipe is loose, and whether the line is aging and connected to electricity, so as to find and repair and replace it in time. In addition, the driver should always pay attention to whether there is a peculiar smell in the car, if there is a peculiar smell, go to the 4S shop in time to carry out comprehensive repair and maintenance of the vehicle, so as to avoid spontaneous combustion caused by aging lines and oil circuits.
For trucks that often run long distances, because the truck is not only heavy, but also heavy, continuous driving for a long time, or continuous braking during driving, is easy to cause overheating of the wheel hub, resulting in spontaneous combustion of the vehicle. On the highway, it is not uncommon for trucks to spontaneously combust due to high tire temperatures. Therefore, truck drivers who often run long distances must water the wheels to cool down on the way.
New energy vehicles are also prone to spontaneous combustion, most of which are caused by batteries, and new energy vehicles use lithium batteries, which essentially rely on redox reactions to work. When charging, the electrical energy is converted into the chemical energy of the substance inside the battery, and when discharged, the chemical energy is converted into electrical energy and released. If the battery is bumped or punctured, it is easy to cause a short circuit between the positive and negative electrodes, and the heat generated by the short circuit will destroy the separator between the positive and negative electrodes, and the positive and negative electrode materials and electrolytes will be mixed together and react violently, and the stored chemical energy will be released uncontrollably, and thermal runaway will occur, so spontaneous combustion will occur. Therefore, avoid charging new energy vehicles in high-temperature environments.
A little more news:
These dangerous goods should never be placed in the car, as they can easily cause spontaneous combustion of the vehicle.
Lighter. Many male drivers like to put lighters in the car, but a small lighter will see high temperatures, which is a big hidden danger. The main ingredient inside the lighter is liquid butane, which is flammable and explosive. As soon as the ambient temperature of the lighter exceeds 55 degrees, the volume will expand. After the vehicle is exposed to the sun, the temperature in the car will reach seventy or eighty degrees, and it is very easy to explode.
Alcohol-based sanitizer. The alcohol content in the alcohol disinfectant is very high, and the temperature in the car is high in summer, and the alcohol is volatile, and it can even cause an explosion when encountering an open flame.
Car perfume. Many exquisite car owners are accustomed to placing car perfume in the car, because many car perfumes are stored in glassware, if you are not careful, it will form a concentrating light and bake the dashboard.
Carbonated drinks. Many car owners like to drink ice-cold carbonated drinks in the summer and forget them in the car when they get out of the car. Carbonated drinks contain a large amount of compressed carbon dioxide, which expands at high temperatures and easily explodes in the car.
Power bank. The general instruction manual of electronic products such as power bank will clearly indicate that they should not be used in high-temperature places. Under high temperature exposure, the car is airtight, and the battery in the power bank is in danger of exploding.
Various canned sprays such as glue removers, hair sprays, insecticides, etc. The filling spray is filled with compressed gas, which will expand when exposed to high temperatures, causing an explosion.
