Car jitter as one of the common problems in the car,Although it seems that "the problem is not big",It only affects our driving mood,But often behind this "minor problem" is hidden in big problems,If the failure is not eliminated in time,It is likely to cause greater hidden dangers,It will be too late to regret it at that time! Today, I will talk to you about the culprits that lead to "car jitter"。

First of all, we have to distinguish whether our car shakes or engine jitter,The distinction method is also very simple。If the car is ignited or the car is still shaking,Then it can be determined as an engine jitter。and if the car starts, it will start to shake,The cause of the jitter can be determined on the body shake。


Reasons for body jitter


There are not many reasons for body jitter,Basically, it can be determined on the chassis problem,The chassis problem that will affect the shake of the body is the following points:


1. The brake disc is not flat

Picture


Because the owner’s driving habit is not good,Frequent heavy braking、Say brake,This may cause problems such as uneven deformation of the brake disc。You will not detect it when you are driving,But whenever you step on the brake, you will be accompanied by the body jitter and the brake feet。To repair the factories for maintenance, generally you will choose to polish and repair,If the wear is severe, it may be replaced。


2. Steering mechanism failure

Picture

When there is a problem with the steering mechanism, it will also cause a car jitter,Especially cars using a hydraulic transmission system,If it turns to help oil, there is a loss of oil,When the steering device fails,,The car is likely to have a jitter when driving。The method of exclusion is,Car jitter that is generally caused by the steering mechanism,The steering wheel will also be accompanied by jitter,Once the source of the fault is determined,Go to repair the factories、4S shop to find professionals for maintenance。


3. Drive the half -axis different heart

Picture


If the semi -axis deformation appears、Bend and other faults,It will cause the two driving semi -axis to not be in the same axis。This situation is generally manifested in the case of the car without problems,Umbrella as soon as it starts,Back to the idle again, there is no problem。If your car is shaking like this,Then you can check the half -axis。


The cause of engine jitter: Most of the car jitter is due to engine jitter,and the problem of engine jitter, as the name suggests, are all on the engine,The following is a common fault point:


1. Lack of fire and lack of fire

Picture


This is the most common reason for engine jitter,None seabet ioof them,Its problem is on the engine ignition coil or spark plug,If there is a problem with the ignition coil or the spark plug cannot be jumped due to some reason,Then the car will have a jitter condition。The lack of cylinder is also a fault type that is better to judge,As long as the car runs at low speed at low speeds, it is much more jitter than usual,and there will be a feeling of accelerating weakness,Then you can basically determine that the engine lacks the cylinder。



2. Severe carbon in the cylinder

Picture


If the carbon deposits in the cylinder are severely caused by the engine spark plug blocked、If the valve is blocked,The problem of engine jitter will also occur。If the car's acceleration ability is not as good as before,If the shake is very long -lasting,Then you can consider cleaning in the engine cylinder。


3. Circuit problem

Picture


Well -known,There are many sensor devices responsible for transmitting engine signals on the engine,such as crankshaft sensor、Blasting sensor, etc.,And if there is a problem with these sensors,It is possible to cause the engine to air intake、Oil injection is affected by poorly affected,The condition of the engine jitter is also very likely。


4. The engine foot pad aging

Picture


This is also a very common cause of jitter,If your car engine shakes more and more serious,But the power has not weakened with it,You can consider whether it is a problem with the pads of the machine。


Summary:The above is more common types of failure that causes "car jitter",It is recommended to collect friends,If the car is shaking, take it out to see it and analyze it,It is not useful to be cleaned by the repair factories several times.。Do you say not?
