What should I do if the car shakes? What to do if the car shakes

1. High-speed jitter.

When driving at high speeds, it may cause shaking, because the front wheel alignment angle will be inaccurate, the air pressure of the tire is too low or deformed because the tire has been repaired before, and it is also likely that the number of screws is different; The propeller shaft is bent and deformed, which can cause the car to shake.

2. Cold start.

If you don't heat up the car before driving and often start cold, it will cause the car to shake because his burning fuel will not be sufficient, and then the car will produce a situation of insufficient power, and when the car starts, if the temperature with the lubricating oil is relatively low, more oil is needed to meet the power. As a result, the gap between the spark plugs keeps getting bigger, which leads to a drop in fire energy, and then the car shakes.

3. Tires. If the weight of your car tires is uneven, it is easy to shiver, so the car tires should be checked regularly, and if your car tires are unevenly matched, you should add lead to the steel rim to comment on the weight of the two tires. The tire pressure should also be checked regularly, and if the tire pressure difference between the two sides is large, it will also cause shaking.

4. The oil pressure is unstable.

If your car is always shaking, you can clean up the carbon deposits in the engine, the throttle is also clear, and the pad will be replaced.

1. When running at high speed, the steering wheel shakes, it may be that the tire balance is not good, you need to do dynamic balance for the two front wheels, and if the vehicle will deviate, then do a four-wheel alignment.

2. If the steering wheel shakes when running at high speed and stepping on the brakes, it is caused by uneven brake pads, and the front brake pads or brake discs need to be replaced.

3. In the process of car acceleration, the body shakes, which requires checking whether there is a problem with the transmission shaft, or checking the gasoline filter element and spark plug, and replacing it in time if there is a problem.

4. The body shakes when the clutch is loosened at the start, and the clutch plate and pressure plate need to be replaced.

5. When stepping on the accelerator at low speed and high end, the body is frustrated, and it is necessary to check whether there is a problem with the spark plug, and if so, the spark plug needs to be replaced.

6. The body shakes when stepping on the accelerator, and the shake disappears after release, and the transmission pump also needs to be checked, and the transmission pump needs to be replaced if necessary.

7. The body shakes when playing the direction, this is because the power belt is too loose or too tight, mainly for mechanical hydraulic power vehicles, adjust the tightness of the belt or replace it.

8. The car shakes when driving at low speed, which may be due to the incorrect ignition advance angle, the bottom of the fuel pressure cooker, the air intake system leakage, the throttle position sensor or air flow meter is faulty, and the fuel injector is working poorly, which needs to be repaired by a professional store.

The reasons for the unsteady driving, head swinging, and even steering wheel shaking of the car at high speed or at a certain high speed are as follows:

1. The positioning angle of the front wheel is inaccurate, and the toe is too large.

2. The air pressure of the front tire is too low or the tire is unbalanced due to repair and other reasons.

3. The front spokes are deformed or the number of tire bolts is different.

4. The installation of transmission system parts is loose.

5. The transmission shaft is bent, the power is unbalanced, and the front axle is deformed.

6. Shock absorber failure.

There are two situations of high-speed oscillation, one is that the oscillation becomes stronger with the increase of vehicle speed, and the other is oscillation occurs at a higher speed, which causes the steering wheel to shake. The drive axle can be erected first, the front wheel is plugged with safety plug blocks, the engine is started and gradually shifted into the high-speed gear, so that the drive wheel reaches the final test oscillation speed. If both the body and steering wheel shake at this time, it is caused by the drivetrain.

Because the front axle of the front wheel is in a stationary state at this time, if the final test oscillation speed is reached, the car does not shake, then the reason for the oscillation is that the front axle part of the car is faulty; Check whether the positioning angle and toe of the front wheel meet the requirements, and adjust if it is out of alignment; Set up the front axle and test the wheels to check the dynamic balance of the wheels and whether the tires are too deformed. If necessary, a good wheel can be replaced for a comparative test; Check whether the front axle and frame are deformed, check whether the transmission shaft is bent, and make the dynamic balance of the transmission shaft when possible.

Answer: The car is shaking, you should control the direction, slow down immediately, and then pull over to stop the car, check the reason, this may be a jealous failure, if you can't find out the reason, you can let the Seth shop to test it, and then go on the road after eliminating the hidden danger.

Idle shaking, the new car has been used for a period of time, and some owners will find that the body has some small shaking, but they don't know that there is a problem. "Body shake" is a sign that something is wrong with the car.

The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox.

The car shakes when driving. Then it needs to be tested in time. Do a four-wheel alignment.

What should I do if the car shakes while driving? Let's find out!

Analysis of the causes of car shake:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in the engine idling speed is too high, and the carbon deposits generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

Generally, when the car accelerates, when stepping on the clutch to shift gears, it will be found that the speed drops sharply, and it will be accompanied by the phenomenon of shaking, especially the performance of manual transmission models is more obvious.

Professionals tell us that body shake seems to be a trivial matter, but if you don't pay attention to detection, it will cause a big failure. So, what is the problem that causes the body to shake? How should ordinary car owners judge and solve?

The automobile engine is the device that provides power for the car, is the heart of the car, and determines the power, economy, stability and environmental protection of the car. According to different power**, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.

Can you describe it clearly?" Vehicle shake involves many aspects. Chassis, oil circuit, circuit, these three kinds of illuminated into jitter occurs.

With the continuous development of social economy, in real life, we will encounter a variety of situations, especially when we encounter the situation when driving, it is very doubtful for many of our car friends, I believe that many friends will encounter the problem of car shaking when driving, when encountering this kind of problem, we only have two options, either to drive to the auto repair shop for related maintenance, or we ourselves to deal with the relevant treatment.

First of all, we must understand such a problem, that is, the car shakes very badly after starting, the most important thing is because the throttle is too dirty, or the fuel injector is caused by too much carbon deposit, in this case, it will make the combustible mixture of the engine very sparse, which will cause us to shake very badly when we start cold, in this case, our best solution is to directly clean the oil circuit, and check whether the idle motor still has carbon deposits, If there is still carbon deposition in the motor, then it is enough to directly deal with it.

Of course, the above is the main reason, we can check the car shake when the above step to help us solve this problem, if we do not solve this problem in this step, we need to check other problems, whether it is caused by high voltage power failure, and whether it is because of the abnormal water temperature This situation, because the engine operating temperature must have a normal range, the water temperature is too high will lead to the phenomenon of engine shakeOnly by eliminating them one by one can we solve this problem.

To sum up, we can obviously know that when we encounter a very strong car shake in our lives, we can use the above steps to help us solve this problem, and generally by solving the main cause, we can directly solve the problem of car shake.

Because the car shake can affect normal driving, and the ride experience is very poor, it should be repaired as soon as possible.

It may be that the engine is shaking, it may be that there is a problem with the ignition system, or it may be that the carbon deposit is more serious, and it can be cleaned and repaired.

I'd consider cleaning up the deposit, and if there's no problem, I'll check some brakes, or check the clutch.

Be sure to have the engine serviced, also check the gearbox, also check the clutch, and also clean up the carbon deposits regularly.

If carbon deposits occur in the valves and intake tracts of the engine, the ECU will make an error in judgment because the carbon deposits can absorb the appropriate amount of fuel. If the computer actually controls the injection of hypothetical 100 parts of oil and gas, but only 90 parts actually enter the cylinder (10 parts are absorbed by carbon deposits), then even if the remaining 90 parts of mixed oil and gas are fully combusted, this cannot achieve the required power, and the phenomenon of jitter is inevitable.

Causes of idle jitter:

1. The engine carbon deposition is serious. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposition inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by a large amount of carbon deposition, and the mixture is too thin due to forest rent, making it difficult to start.

After landing, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine and burned, which will thicken the mixture. The mixture is sometimes dilute and sometimes thick, which will cause idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold starts, and the more the presence of carbon deposits affects cold starts.

The solution is to clean the carbon deposits at the throttle and injector.

2. Poor ignition system and poor ignition of spark plugs will also lead to engine idling and shaking. If there is a problem, check if the ignition system is faulty and if there is too much carbon deposited in the spark plug.

3. The oil pressure is unstable. If you have cleaned the engine carbon deposits, cleaned the throttle valve or replaced the spark plug, and there is still the problem of body shaking when idling, it is recommended to go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the oil pump supply pressure is not normal or the intake pressure sensor is incorrect, it can also cause the body to shake when idling.

Solution: Ode to friends;

The best way is to clean the oil circuit, clean it regularly, there is no specific experience in the research and development parameters of the clean engine from the new car, coupled with the continuous improvement of emission standards, can not adapt to the change of fuel, all manufacturers of the engine are unable to solve this jitter problem in the short term, plus the fuel quality is not very good or the initial fuel of the new car factory is stored for too long, resulting in a rapid increase in the colloidal composition of the oil circuit, which will continue to pollute the fresh fuel and cause no good fuel to participate in combustion in the later stage. The occurrence of excessive carbon deposits is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits. The use of PNF dope fuel additives can solve the problems caused by carbon deposition.
