汽車抖動的原因是什麼？What are the causes of car shaking?

汽車抖動的原因是:
1.燃油燃燒不充分，汽車動力不足，造成啟動時抖動。
2.發動機積碳嚴重、點火系統問題、油壓不穩、發動機部件老化等原因造成汽車意速抖動。
3.輪胎氣壓過高或過低、輪胎磨損異常、減震器失效、輪胎動平衡、車輪定位資料偏差大等原因造成高速抖動。
汽車抖動重要原因和故障解決方法
1.原地空擋位空轉，車身抖動、振動。
車輛啟動後，怠速回到正常速度。我們會發現身體在顫抖，振動加劇。我們在使用汽車時會脫離正常狀態。用手觸摸車身飯金，可以發現明顯的震感。
問題解決方法:
很可能是你的發動機安裝橡膠墊老化或損壞，影響減振效果。安裝橡膠墊可以過濾發動機旋轉過程中的大部分振動。但如果損壞，就會失去減振濾波的效果，振動也會相應傳遞到車身。
2.行駛中高速方向盤晃動或跳動
高速行駛到一定速度範圍時，方向盤可以感覺到明顯的晃動或跳動，但其他速度範圍則不明顯或沒有.在這樣的情況下，我們可以先排除發動機故障的問題，因為如果是發動機故障的問題，低速時也可能會發生抖動和振動。
如果只是高速晃動振動顯著，我們可以先目測一下輪圈上是否有大量泥塊，或者平衡鉛塊是否缺失，或者輪毅是否有明顯變形。以上地方基本都沒問題的話，可以先做個動平衡，沒有解決的話，需要檢測轉向杆、懸架、輪毅等的輕微變形。
解決方法:
汽車使用一段時間後，由於碰撞、左右路齒頻繁或過坑不減速，基本上不會影響懸架、減震器、輪的意外變形，或者球頭、輪胎的不規則磨損。一般可以通過調整底盤懸掛位置、前束角或更換輪胎來解決。
3.發動機積碳
有些老爺車容易發動機積碳。老爺車長時間使用後，發動機內積碳容易受到影響，氣缸分佈不均會影響進氣不足和燃燒，是造成發動機抖動和振動的重要原因。
解決方法:
提倡車主需要去專業的汽修店檢查
4.火花塞不好用。
汽車因為火花塞而抖動和振動有一個非常大的原因。我想我也可以換火花塞。汽車晃動多是火花塞積碳、火花塞堵塞等
解決方法:
火花塞的成本不一定貴。你車子的保養手冊基本上標明了你需要更換多少公里，車主也可以馬上更換
5.起動發動機油壓不穩定等故障原因
汽車易動還有一個原因，就是油壓不定。這種油壓不穩定意味著燃油壓力不穩定，各缸噴油量不均勻，燃油混合氣燃燒不均勻，也可能影響發動機抖動和汽車抖動
解決方法:
油壓不穩定很重要，可能是因為油壓調節器壞了，燃油濾清器被一些垃圾堵住了。

The causes of car shaking are:
1. Insufficient fuel combustion and lack of power, resulting in jittering when starting.
2. Serious carbon deposits in the engine, ignition system problems, unstable oil pressure and ageing engine components cause the car to shake at speed. 3. High-speed shaking caused by high or low tyre pressure, abnormal tyre wear, shock absorber failure, tyre balancing and large deviations in wheel alignment data.
The key causes of car shaking and fault solving methods
1. The car shakes and vibrates when idling in the neutral position.
After starting the vehicle, the idle speed returns to normal speed. We will find that the body is shaking and the vibration is intensified. We will be out of the normal state when using the car. If you touch the body of the car with your hand, you will notice a distinct vibration.
Solution:
It is likely that your engine's rubber gasket is old or damaged, affecting the damping effect. Installing a rubber pad will filter out most of the vibration during engine rotation. However, if they are damaged, the filtering effect will be lost and the vibration will be transmitted to the vehicle accordingly.
2. Steering wheel shaking or jumping at high speed while driving
When driving at high speeds, the steering wheel can feel a noticeable wobble or bounce in a certain speed range, but not in other speed ranges. In this case, we can first rule out the problem of engine failure, because if it is a problem of engine failure, shaking and vibration may also occur at low speeds.
If the shaking and vibration is only significant at high speed, we can first visually inspect the rim for large amounts of mud, or if the lead balance is missing, or if the wheel is significantly deformed. If all of these areas are basically OK, we can do a dynamic balancing first. If this does not solve the problem, we need to check the steering rod, the suspension and the wheels for slight deformation.
Solution:
After the car has been in use for a period of time, due to collisions, frequent left and right gearing, or over potholes without slowing down, there is basically no accidental deformation of the suspension, shock absorbers, wheels, or irregular wear of the ball and tyres. This can generally be solved by adjusting the suspension position of the chassis, the front beam angle or changing the tyres.
3. Carbon build-up in the engine
Some older cars are prone to carbon build-up in the engine. The uneven distribution of cylinders will affect the lack of air intake and combustion, which is an important cause of engine shaking and vibration.
Solution:
Advise the owner to go to a professional garage for inspection.
4. Bad spark plugs.
There is a very big reason why a car shakes and vibrates due to spark plugs. I think I can also change the spark plugs. Most of the shaking is due to carbon build-up in the spark plugs, clogged spark plugs, etc.
Solution:
The cost of spark plugs is not necessarily expensive. The maintenance manual for your car basically states how many kilometres you need to replace them, and the owner can replace them right away.
5. Unstable starter oil pressure and other causes of failure
Another reason why your car is prone to start-ups is that the oil pressure is unstable. Unstable oil pressure means unstable fuel pressure, uneven injection of fuel into each cylinder and uneven combustion of the fuel mixture, which may also affect engine shaking and car shaking.
Solution:
Unstable oil pressure is very important, probably because the oil pressure regulator is broken or the fuel filter is blocked by some rubbish.
