    自己的爱车维修的知识介绍
    2021-9-11 14:23:17

    首先要检查分电器、火花塞、高压线等是否因为汽车淋雨等受潮,如果是这样,可以把受潮机件晾干,然后再发动。

    First of all, check whether the distributor, spark plug and high-voltage line are affected by moisture due to the rain of the car. If so, dry the affected parts before starting.

    其次,检查火花塞是否损坏,如果损坏,只要更换新火塞即可。

    Secondly, check whether the spark plug is damaged. If it is damaged, just replace it with a new one.

    第三,检查蓄电池电压是否足够。有的时候,停车忘记关灯,时间长了,就可能耗尽电源。如果是这样,把车挂二挡,脚踩离合,用车拖拽,当行驶到一定速度时,松开离合,拧动点火开关,汽车就能自然启动,如果是蓄电池有问题,此法不能奏效。

    Third, check whether the battery voltage is sufficient. Sometimes, if you forget to turn off the lights after parking, you may run out of power for a long time. If so, put the car in second gear, step on the clutch and drag the car. When driving to a certain speed, loosen the clutch and turn the ignition switch, the car can start naturally. If there is a problem with the battery, this method can't work.

    换挡时发动机熄火

    The engine stalls when shifting gears

    行进中换挡,如果操作规范,但出现熄火现象,需要检查以下问题:

    When shifting gears on the road, if the operation is standard but the engine stalls, the following problems need to be checked:

    首先看怠速是否稳定,怠速是否过低,如果怠速不稳或怠速低,只要把怠速调整到正常转速即可。还要把怠速截止阀拧紧,插头插紧。

    First, check whether the idle speed is stable and whether the idle speed is too low. If the idle speed is unstable or low, just adjust the idle speed to the normal speed. Also tighten the idle stop valve and plug it tightly.

    其次,如果怠速正常,则可能是油气分离器被堵塞,需要到专业修理站清洗油气分离器。

    Secondly, if the idle speed is normal, the oil-gas separator may be blocked, and it is necessary to clean the oil-gas separator in a professional repair station.

    高速行驶时方向盘震颤

    Steering wheel tremor at high speed

    汽车在高速行驶或在某一较高车速行驶时出现行驶不稳、摆头,甚至方向盘抖动,出现这种情况的原因有如下几点:

    When the vehicle is driving at high speed or at a high speed, it may run unsteadily, swing its head, or even shake the steering wheel. The reasons for this are as follows:

    1、前轮定位角失准,前束过大。

    1. Misalignment of front wheel alignment angle and excessive toe in.

    2、前轮胎气压过低或轮胎由于修补等原因起动不平衡。

    2. The front tire pressure is too low or the tire starts unbalanced due to repair and other reasons.

    3、前轮辐变形或轮胎螺栓数量不等。

    3. The front wheel spokes are deformed or the number of tire bolts varies.

    4、传动系统零部件安装松动。

    4. Loose installation of transmission system parts.

    5、传动轴弯曲,动力不平衡,前轴变形。

    5. The transmission shaft is bent, the power is unbalanced, and the front axle is deformed.

    6、减震器故障

    6. Shock absorber failure

    高速振摆有两种情况,一是随着车速的提高振摆渐强烈,二是在某一较高车速出现振摆,并引起方向盘抖动。可以先架起驱动桥,前轮加塞安全塞块,启动发动机并逐步换入高速挡,使驱动轮达到终试摆振速度。若此时车身和方向盘都出现抖动,启动发动机并逐步换入高速挡,使驱动轮达到终试摆振速度。

    There are two cases of high-speed shimmy. One is that the shimmy becomes stronger with the increase of vehicle speed, and the other is that the shimmy occurs at a higher vehicle speed and causes the steering wheel to shake. You can first set up the drive axle, plug the safety plug on the front wheel, start the engine and gradually shift into the high gear to make the drive wheel reach the final test shimmy speed. If the body and steering wheel shake at this time, start the engine and gradually shift into high gear to make the driving wheel reach the final test shimmy speed.
