現在很多人都有車，可能開車大家都沒問題，但關于汽車壞了需要怎么維修就，大家不是很懂了，比如車子準備啟動卻發現發動機無法啟動等，這感覺就不是很好了。下面
濟南沃爾沃汽車維修哪家好廠家來介紹下一些簡單汽車基礎維修知識：
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 .無法啟動
1、 Unable to start
先要檢查高壓線等是否因為汽車淋雨等受潮，如果是這樣，可以把受潮機件晾干，然后再發動。檢查火花塞是否損壞，如果損壞，只要更換新火花塞即可。檢查蓄電池電壓是否足夠。有的時候，停車忘記關燈，時間長了，就可能耗盡電源。
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.
如果是這樣，把車掛二擋，腳踩離合，用車拖拽（一般不建議，找人推一下），當行駛到一定速度時，松開離合，擰動點火開關(一般不建議，應當在推到之前將點火開關開到上)，汽車就能夠啟動。如果是發電機有問題，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. 高速行駛時方向盤震顫
II Steering wheel trembles when driving at high speed
汽車在高速行駛或在某一較高車速行駛時出現行駛不穩、擺頭，甚至方向盤抖動，出現這種情況的原因有如下幾點：
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、前輪定位角失準，前束過大。
1. Front wheel alignment angle misalignment, excessive toe in.
2、前輪胎氣壓過低或輪胎由于修補等原因起動不平衡。
2. The front tire pressure is too low or the tire starts unevenly due to repairs or other reasons.
3、前輪輻變形或輪胎螺栓數量不等。
3. Distorted front wheel spokes or varying number of tire bolts.
4、傳動系統零部件安裝松動。
4. Loose installation of transmission system components.
5、彎曲，動力不平衡，前軸變形。
5. Bending, power imbalance, front axle deformation.
6、故障。
6. Fault.
如果定位橋頭等都沒問題可以先去做一下輪胎動平衡
If there are no issues with positioning the bridge head, you can first perform tire dynamic balancing
三. 轉向沉重
III Heavy steering
轉向沉重的原因較多，但通常有以下幾點：
There are many reasons for heavy steering, but there are usually the following:
1、輪胎氣壓不足，尤其前輪氣壓不足，轉向會比較吃力。
1. Insufficient tire pressure, especially in the front wheels, can make steering more difficult.
2、助力轉向液不足，需添加助力轉向液。
2. Insufficient power steering fluid, need to add power steering fluid.
3、前輪定位不準，需進行檢測。
3. The front wheel alignment is not accurate and requires testing.
四. 行駛時跑偏
IV Driving with deviation
檢查跑偏，一般是在行駛時，擺正方向盤，然后放開方向盤行駛，看汽車是否走直線。如果不走直線，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.
跑偏可能是因為左右輪胎氣壓不一致造成的，需給不足的輪胎充氣。
The deviation may be caused by inconsistent air pressure between the left and right tires, and insufficient tires need to be inflated.
可能是前輪定位不準。前輪外傾角、主銷角或主銷內角不等，前束太小或負前束都會造成跑偏，必須到專業維修站檢測。
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.
