现在很多人都有车，可能开车大家都没问题，但关于汽车坏了需要怎么维修就，大家不是很懂了，比如车子准备启动却发现发动机无法启动等，这感觉就不是很好了。下面
济南沃尔沃汽车维修哪家好厂家来介绍下一些简单汽车基础维修知识：
Nowadays, many people have cars, and driving may not be a problem for everyone. However, when it comes to how to repair a broken car, people are not very familiar with it. For example, when the car is ready to start but the engine cannot start, it doesn't feel very good. Which good manufacturer in Jinan Volvo Car Maintenance will introduce some basic automotive maintenance knowledge
一 .无法启动
1、 Unable to start
先要检查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。检查火花塞是否损坏，如果损坏，只要更换新火花塞即可。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。
First, check whether the high-voltage line is damp due to rain or other factors in the car. If so, the damp parts can be dried before starting. Check if the spark plug is damaged. If it is damaged, simply replace it with a new spark plug. Check if the battery voltage is sufficient. Sometimes, if you forget to turn off the lights when parking, you may run out of power over time.
如果是这样，把车挂二挡，脚踩离合，用车拖拽（一般不建议，找人推一下），当行驶到一定速度时，松开离合，拧动点火开关(一般不建议，应当在推到之前将点火开关开到上)，汽车就能够启动。如果是发电机有问题，此法不能奏效。
If that's the case, put the car in second gear, step on the clutch, drag the car (generally not recommended, find someone to push), and when driving to a certain speed, release the clutch, turn the ignition switch (generally not recommended, the ignition switch should be turned on before pushing), and the car can start. If there is a problem with the generator, this method cannot work.
二. 高速行驶时方向盘震颤
II Steering wheel trembles when driving 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，甚方向盘抖动，出现这种情况的原因有如下几点：
There are several reasons why a car may experience unstable driving, head sway, or even steering wheel shaking when driving at high speeds or at a certain high speed:
1、前轮定位角失准，前束过大。
1. Front wheel alignment angle misalignment, 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 unevenly due to repairs or other reasons.
3、前轮辐变形或轮胎螺栓数量不等。
3. Distorted front wheel spokes or varying number of tire bolts.
4、传动系统零部件安装松动。
4. Loose installation of transmission system components.
5、弯曲，动力不平衡，前轴变形。
5. Bending, power imbalance, front axle deformation.
6、故障。
6. Fault.
如果定位桥头等都没问题可以先去做一下轮胎动平衡
If there are no issues with positioning the bridge head, you can first perform tire dynamic balancing
三. 转向沉重
III Heavy steering
转向沉重的原因较多，但通常有以下几点：
There are many reasons for heavy steering, but there are usually the following:
1、轮胎气压不足，尤其前轮气压不足，转向会比较吃力。
1. Insufficient tire pressure, especially in the front wheels, can make steering more difficult.
2、助力转向液不足，需添加助力转向液。
2. Insufficient power steering fluid, need to add power steering fluid.
3、前轮定位不准，需进行检测。
3. The front wheel alignment is not accurate and requires testing.
四. 行驶时跑偏
IV Driving with deviation
检查跑偏，一般是在行驶时，摆正方向盘，然后放开方向盘行驶，看汽车是否走直线。如果不走直线，就是跑偏。
Check for deviation, usually by aligning the steering wheel while driving, then releasing the steering wheel and driving to see if the car is running in a straight line. If you don't follow a straight line, it's a deviation.
跑偏可能是因为左右轮胎气压不一致造成的，需给不足的轮胎充气。
The deviation may be caused by inconsistent air pressure between the left and right tires, and insufficient tires need to be inflated.
可能是前轮定位不准。前轮外倾角、主销角或主销内角不等，前束太小或负前束都会造成跑偏，必须到维修站检测。
It may be due to inaccurate front wheel alignment. The front wheel Camber angle angle, kingpin angle or kingpin internal angle are not equal, and the toe in is too small or negative, which will cause deviation, so you must go to a professional maintenance station for detection.
