    驾车人能掌握哪些基本汽车维修技巧?
    2021-11-17 19:05:34

    车辆故障大致可分为三部分

    Vehicle faults can be roughly divided into three parts

    一是电路故障

    First, circuit failure

    二是油路故障

    Second, oil circuit failure

    三是行驶系统故障,如转向、制动、传动部分等。

    The third is driving system failure, such as steering, braking, transmission, etc.

    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,车辆的故障约大多数是电路故障,再就是在油路方面,这些故障大部分自己能排除。只有很少一部分是行驶系统故障,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。

    Among them, circuit faults are divided into high-voltage circuit and low-voltage circuit faults. In actual use, most of the vehicle's faults are circuit faults, and then in the oil circuit, most of these faults can be eliminated by themselves. Only a few of them are driving system faults. These faults belong to mechanical faults. Most of the vehicles can still drive when they occur. They should be repaired at the nearest special maintenance station.

    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 a fault while driving, first, don't worry, second, don't get busy. First, look at the reflection of the fault indicator. Calm down, analyze the fault phenomenon and ask more why? There are two ways to judge and distinguish oil circuit faults: one is whether the engine suddenly stalls or slowly stalls during driving. Most of the sudden stalls are circuit faults; The slow flameout, or the continuous "jump" phenomenon of the vehicle, is mostly oil circuit failure. The second is "fire test". If there is no cylinder fire, it is a circuit fault. If there is a high-voltage fire, the problem is in the oil circuit. Most mechanical faults are accompanied by abnormal sound. The sound changes with the speed of the vehicle. The sound disappears when stopping, which is not directly related to the oil circuit fault.

    用“逐段否定法”,将“焦点”锁定在一个特定的地方,先弄明白是属于哪一类故障,有针对性地先查看外部是否异常。如电线有否断路、短路,连接部位有否松动;发动机里有无电线的烧糊味,油路管道有否漏油等等。

    Use the "paragraph by paragraph negative method" to lock the "focus" in a specific place, first find out what kind of fault it belongs to, and then check whether the external fault is abnormal. If the wires are open or short circuited, and if the connecting parts are loose; Whether there is burning smell of wires in the engine, whether there is oil leakage in the oil pipeline, etc.

    值得提醒的是,现在的新车大多是“电喷”车,是电子控制燃烧,故障较少,与老的化油器车故障概率恰好相反。需要记住的是,电喷车如电路发生故障,往往需要专用电脑检测仪检测,驾驶员切忌自己动手,以免破坏电路程序。

    It is worth reminding that most of the new cars are "EFI" cars, which are electronically controlled combustion and have few faults, which is just the opposite to the failure probability of the old carburetor cars. It should be remembered that if the circuit of EFI vehicle fails, it often needs to be detected by a special computer detector. The driver should avoid doing it by himself to avoid damaging the circuit program.
