How do you know the condition of the vehicle and how to judge the fault according to the abnormal smell?

In general, car spontaneous combustion is first smoke, and then burn, if the owner of the usual vigilance, when the smell of abnormal smell, early parking inspection, fire events may be avoided. Therefore, the car friend can smell the abnormal smell, check where the car is out of order. A car consists of at least 7000 parts. These parts are metal, plastic, and rubber. In abnormal wear and consumption, they make a sharp smell, such as burnt, odour, plastic and so on. According to the smell, we can judge some of the malfunctions of the vehicle with the nose. . This odor is the most distinguishable. First check the belt, brake shoe, and tire to see if the rubber products in these parts are slack or overheated. If they are found to be the smell of brakes or tires, stop immediately, and then drive again after heat. This situation is mostly caused by overheating of the electrical circuit. Because the plastic outer sheath of electric wires is thin, the smell is not very large. However, when the wire is short circuited, it is accompanied by local smoke or fever. It is easy to cause combustion and fire because of the long time. Once the wire is overheated, it is necessary to stop immediately to find out the cause. It is not obvious that the smell of wire burning is small, but the danger index is very high. In general, the temperature of the wire is too high in summer. If it is not found in time, it is easy to cause the complete damage of the circuit, the engine cylinder, and even the self ignition of the whole vehicle. In the process of driving, if you smell the special smell of non-metallic materials burning, it is usually caused by burning or overheating of clutch friction plates. This smell will also be smelly, because the material of the clutch disc is made of rubber and asbestos and other materials. If the clutch is used normally, and there is no obvious difficulty in hanging or starting, and the smell from the car comes from the rear of the car, then check whether the brake system is overheated. Some careless owners drive under the condition of a handbrake, which will make the rear brake block locked and cause the smell of coke. If the car can smell unburned gasoline, it should arouse the attention of the riders. First, determine the location and extent of oil leakage before driving on the road again. When the vehicle is used for a long time, the oil pipeline will suffer from aging and cracking, and the fuel will leak out from these parts. Therefore, when the car friend smells the smell of gasoline, it should stop the fire immediately, put out the clear fire and so on, and thoroughly check the oil road. If the fuel tank leaks oil, there is an urgent way to plug the leaking oil with chewing gum and then repair it as soon as possible. This smell is common in carburetor cars, people commonly known as "oil burning", in addition to smelling the smell of people, the exhaust tube will also smoke black smoke. One situation is due to the serious wear of the inner wall of the cylinder or the serious wear of the piston, the oil jumping into the engine combustion chamber; the other is the serious wear of the valve and the possible burning of the oil; and the aging of the oil pipe of the vehicle, the oil drop to the engine or the exhaust pipe, and the bad air in the case of high temperature. Taste. Most of this is the leakage or loss of the electrolyte, which occurs mostly in the wet battery, because the battery needs to be stored and converted by the electrolyte, but when the electrolyte leaks, it will produce a pungent taste; at the same time, if the electrolyte is too much or a loss, the car will be fired. The motor will charge the battery vigorously, which will make the battery overheating and white smoke, and the smell will be even worse. To find this problem, electrolyte should be replenished in time and charged to the battery.
