Why do you shake the car? You have to know these reasons.

Chews know that car jitter is one of the most common problems in cars. Some people think it is a small problem, but often there are big problems behind this "small problem". If you do not eliminate the problem in time, it is likely to cause a bigger hidden danger.

First of all, we need to distinguish whether the body is shaking or the engine is shaking: if the car is shaking from the start of ignition, it can basically be determined that the engine is shaking; if the car starts to shake after starting, it can be determined that the body is shaking.

Body shake
Brake disc is not flat
The poor driving habits of the owner, such as frequent braking and sudden braking, may cause problems such as uneven deformation of the brake disc. It doesn"t feel like driving when you are driving, but when you step on the brakes, it will be accompanied by body shake and brakes.
Tire problem
The vehicle has slight jitter or some swing during the driving process. It may be that the tire is deformed or the cause of the imbalance. Check the tires as soon as possible and make a four-wheel balance.
Steering mechanism failure
Problems with the steering mechanism can also cause car shake, especially in cars with hydraulic transmission systems. If the steering power is lost, and the steering device fails, the car is likely to be shaken while driving.
Drive the half shaft differently
The car axle is the final drive for the power transmission of the car engine, which causes the drive wheels to rotate and push the car forward or backward. If the half shaft is deformed or bent, it will cause the car to shake. This kind of situation is generally manifested in the case of the car idling without problems, it will shake when it is opened, and it will be no problem when it returns to idle speed again.

Body shake
Lack of fire
If there is a problem with the ignition coil or if the spark plug cannot jump for some reason, the combustion efficiency of the engine will be reduced and the car will be shaken. If the car is much more dither than usual when running at low and medium speeds, and there is a sense of powerlessness during acceleration, it can be basically determined that the engine is out of cylinder.
Too much carbon
After the car has traveled for a certain mileage, the throttle may be too tight due to excessive dirt or the idle stepping motor may be stuck, which may cause the engine to idle too high. The carbon deposits generated by the engine during operation can also cause vehicle shake. If the car"s acceleration ability is not as good as before, and the jitter is very long, then you can consider the engine cylinder cleaning.
Engine mat mat aging
This is often the case with older cars. The engine"s base pad is actually a suspension system for the engine, which is responsible for filtering some of the slight jitter generated by the engine at high speeds. When the mat is aged, the vibration of the engine is transmitted to the entire body. If your car"s engine is getting more and more jittery, but the power is not getting weaker, you can consider whether it is a problem with the engine floor mat.
Circuit problem
There are many sensor devices on the engine that transmit engine signals, such as crankshaft sensors, knock sensors, and more. If there is a problem with these sensors, the engine intake and fuel injection may be adversely affected. These problems may affect the engine ignition and engine shake.
