The use of cars for a long time will inevitably lead to some problems. Xiao Bian will give you a trick to judge car faults by smelling unusual odors. If you don’t believe it, then let’s take a look.
Plastic paste
This situation is mostly caused by the overheating of the electrical wiring. Since the plastic wrapping of the wire is thin, the odor is not great. However, when the wire is short-circuited, it is often accompanied by local smoke or heat. Burning, causing fire.
Once the wire overheating is discovered, it must be stopped immediately to find out the reason. Don't look at the odor of burning the wire, but the risk index is very high. In general, if the wire temperature is too high in summer, there will be more, if not. Found that it is easy to cause complete circuit damage, engine pull cylinder, and even the whole vehicle spontaneous combustion phenomenon.
Thick smell
In the course of driving, if a special odor of non-metallic materials is burned, it is usually caused by the burning or overheating of clutch friction plates. This odor may also be accompanied by coke odor because the material of the clutch plate is made of rubber. Asbestos and other materials from a composite.
If the clutch is used normally, there is no obvious difficulty in getting stuck or the starting is difficult, and the smell of getting off the car comes from the back of the car, then check whether the rear brake system is overheated. Some careless The owner is forcibly driving while holding the handbrake, which will cause the rear brake pad to lock up and produce a scorching odor.
Unburned petrol smell
If there is always an unburned smell of gasoline in the compartment, it should cause the rider's high attention. First determine the location of the oil spill and the level of oil leakage before you can go on the road again.
After long-term use of the vehicle, the oil pipeline will be aged and cracked, and fuel will leak from these parts. Therefore, when the rider smells the smell of gasoline, stop and stop immediately, eliminate the open flames such as cigarettes, and thoroughly inspect the oil circuit. There is an emergency solution to the oil spill in the fuel tank. It is to use a chewing gum to plug the oil spill and repair it as soon as possible.
Burning oil
This odor is more common in carbureted cars, commonly known as 'burning oil'. In addition to smelling stench, the exhaust canister emits black smoke. In one case, the inner wall of the cylinder is worn out. Severe or serious piston wear, oil intrusion into the engine combustion chamber; Another situation is serious valve wear, it may burn oil; And the vehicle's oil pipeline aging, oil dripping on the engine or exhaust pipe, in the case of high temperature Next, it will emit an unpleasant odor.
Battery odor
Most of these cases occur because of leakage or loss of electrolyte. This phenomenon occurs mostly in wet batteries because the battery needs to be stored and converted by the electrolyte, but when the electrolyte leaks, it will generate a kind of thorn. The smell of the nose; At the same time, if the electrolyte is consumed too much or is depleted, the vehicle generator will forcibly charge the battery. At this time, the battery will overcharge and overheat and emit white smoke. The odor is even more unpleasant. If this problem is found, electrolysis should be promptly supplemented. Liquid, and charge the battery.
