It is inevitable that some faults will occur in the use of the car. For those experienced old drivers, they can often find the place where the problem lies in one step, but most of them are helpless. Take advantage of the time now, hurry to learn to find your own fault!
Some basic car maintenance skills that drivers should master
车辆故障大致可分为三部分:一是电路故障;二是油路故障;三是行驶系统故障,如转向、制动、传动部分等。其中,电路故障又分为高压电路和低压电路故障。在 实际使用中,车辆的故障约有60%是电路故障,30%在油路方面,这些故障大部分自己能排除。只有10%左右是行驶系统故障,这些故障属于机械故障,发生 时车辆大多还能行驶,应就近去特约维修站修理。
Vehicle fault can be roughly divided into three parts: first, circuit fault; second, oil circuit fault; third, driving system fault, such as steering, braking, transmission part, etc. Among them, the circuit fault is divided into high-voltage circuit and low-voltage circuit fault. In practice, about 60% of the vehicle's faults are circuit faults, and 30% are oil circuit faults. Most of these faults can be eliminated by themselves. Only about 10% of them are driving system faults. These faults belong to mechanical faults. When they happen, most of the vehicles can still drive, so they should go to the nearest special maintenance station for repair.
当你在行驶中发生故障时,一不要着急,二不忙动手,先看看有关故障指示灯的情况反映。静下心来,分析一下故障的现象,多问几个为什么?判断、区分油电路故 障的方法有两个:一是行驶途中是突然熄火还是慢慢熄火,突然熄火大多为电路故障;而慢慢熄火,或者车辆不断发生“蹿动”现象,大多是油路故障。二是“试 火”,如没有中央高压火、分缸火,则是电路故障,如有高压火,问题则在油路。而机械故障大多伴有不正常的声音,声音随车速快慢而变化,停车时声音消失,与 油电路故障没有直接关系。
When you have trouble in driving, first, don't worry, second, don't rush to work. First, look at the situation of the trouble indicator. Calm down, analyze the fault phenomenon, and ask more why? There are two ways to judge and distinguish the fault of oil circuit: one is to suddenly or slowly turn off the engine while driving, which is mostly circuit fault; the other is to slowly turn off the engine, or the vehicle keeps "jumping" phenomenon, which is mostly oil circuit fault. The second is "fire test". If there is no central high-pressure fire or cylinder fire, it is a circuit fault. If there is high-pressure fire, the problem is in the oil circuit. However, most mechanical faults are accompanied by abnormal sound, which changes with the speed of the vehicle. When the vehicle stops, the sound disappears, which is not directly related to the fault of the oil circuit.
With the method of "phase by phase negation", lock the "focus" in a specific place, first find out what kind of fault it belongs to, and then check whether the external is abnormal. Such as whether the wire is open or short circuited, whether the connection part is loose, whether there is burning smell of the wire in the engine, whether there is oil leakage in the oil pipeline, etc.
It is worth mentioning that most of the new cars now are "EFI" cars, which are electronically controlled combustion, with fewer failures, just the opposite of the failure probability of the old carburetor cars. It should be remembered that if the circuit of the EFI vehicle breaks down, it often needs to be detected by a special computer detector. The driver must not do it by himself to avoid damaging the circuit program.
