The car shook for a while on the road, what went wrong?

It could be caused by a mismatch between the speed and gear of the car, or it could be caused by a neutral gear, or it could be due to a malfunction of the engine.

It may be that there is a problem with the engine, because the engine is not powerful enough, there will be a situation of shaking, and this situation needs to be stopped for inspection.

The spark plug is blocked, the combustion efficiency of the engine is not very good, the engine leaks, the car is not maintained in time, and the car burns oil.

The body shakes during driving, which can mean that the vehicle has one of the following four situations:

2. The oil pressure is unstable. If you've cleaned the carbon deposits in the engine, cleaned the throttle valves, replaced the oil pads and spark plugs, and still notice that the body shakes when idling, it is recommended to check that the fuel supply pressure and intake pressure sensors are normal. Normal in 4S shop.

If the fuel pump supply pressure intake pressure sensor value is abnormal or incorrect, poor operation will cause the body to shake. Solution: Check the oil pressure and replace the parts if necessary.

3. Aging of engine parts. Car shake is also associated with the aging of the engine feet. The engine feet are actually the shock absorption system of the engine.

The engine feet are responsible for absorbing the slight shake of the engine when it is running. If there is a problem with the engine feet, these vibrations can be transmitted to the steering wheel and cab, causing idle jitter.

Extended information: 1. The oil pressure is unstable. If you have cleaned up the engine carbon deposits, cleaned the throttle valves, replaced the oil pads and spark plugs, etc., and still find that the body shakes when idling, it is recommended to check the fuel supply pressure and intake pressure sensors at the 4S shop. If the fuel pump supply pressure is abnormal or the value is incorrect, the intake pressure sensor will not work well and cause the body to shake.

2. Engine parts may be aging, such as engine foot aging, which may lead to body shaking. The engine feet are actually the shock absorption system of the engine. The engine feet are responsible for absorbing the slight shake of the engine while it is running.

If there is a problem with the engine feet, these vibrations are transmitted to the steering wheel and cab.

If there is a slight shaking of the body during driving, it is generally a tire failure, you can check the tires and do a dynamic balance test.

It is very likely that there is some problem with the engine, and it may be that the engine has too much carbon deposit.

It may be due to damage to the spark plug, insufficient combustion of the mixture, insufficient ignition of the spark plug, wear of the spark plug at several points, and increased low carbon of the throttle.

If there is a problem with the parts of the car, you should drive the car to the after-sales service store and let a professional master repair your car.

Analysis of the causes of car shake:

1. Cold start jitter.

First of all, starting from the cold start, the main reason for the cold start body shaking is that the fuel combustion is insufficient, resulting in insufficient power of the car. The ignition energy is low, and when starting, especially when the temperature of the fuel and lubricating oil is low, more oil is required to meet the power. Over time, the pole gap of the spark plug gradually increases, resulting in a decrease in ignition energy and poor fuel atomization, which leads to the shaking of the body.

In addition, the ignition energy can also be reduced due to the aging of the ignition coil, the aging of the high-voltage wire of the spark plug, or the leakage of electricity.

2. 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.

3. 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.

4. 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.

5. 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.

After using the car for a while, the shaking seems to be getting worse and worse, but it doesn't feel like it affects the driving, so I ignored it. What many car owners don't know is that the body shakes is a signal that the car tells the owner that there is a problem in a certain part. If it is not dealt with in time, it will seriously affect the safety of driving, and it should be inspected or repaired in time.

Many car owners will find abnormal shaking when starting. This jitter is called idling jitter. The main reason for this problem is the serious carbon deposition of the engine, the aging of some parts of the engine, and the unstable oil pressure.

If there is a problem with the ignition system, the quality of the oil added is too poor, and it does not feel normal, please go to the maintenance shop in time to check. I believe everyone is aware that the consequences can be fatal at any time. The importance of driving safety cannot be overstated.

Many bloody examples warn us that we must wear seatbelts when we enter a car.

When driving, be sure to concentrate and not get distracted. You can't do it all at once while driving. When the car is driving on the road at a speed of 60 kilometers per hour, if the owner glances at the text message at this time, the car may have traveled more than 30 meters, which is enough for any accident to occur.

When driving, never or try not to do anything else that is not related to driving. When you're upset, you're better off trying not to drive or control yourself. Keep your head above water while driving.

When you are tired and want to sleep, try not to drive. Don't drink and drive. Alcohol or certain drugs can delay reaction time and affect judgment and coordination.

Speeding is the most common and the most likely to cause serious traffic accidents. It will narrow the driver's field of vision, weaken his vision, and prolong the reaction distance, making it difficult to effectively respond to sudden dangers ahead. The braking distance of a vehicle is mainly limited by the speed of the vehicle.

Due to the effect of inertia, the faster the vehicle, the greater the braking distance, thus increasing the likelihood of accidents. A motor vehicle driver's license is a legal document that allows motor vehicles to drive on the road in China. A driver's license consists of three parts, a driver's license folder, a main page, and a sub-page.

The front page is an annotated certificate core and the back is a motor vehicle**, sealed in a plastic envelope.

This is caused by uneven ground, which increases the friction of the car and causes jitter.

This could be because your car's engine is malfunctioning, or it may be because parts of your car are damaged.

It is very likely that the car is out of oil, so some shaking will occur in the process of driving, and the shaking of the car is more obvious, and some oil can be added appropriately.

Possible reasons why the car is shaking at high speed:

1. Tire problems: mainly due to abnormal tire pressure or serious tire wear.

Tire pressure too high or too low: Tire pressure differences between four tires are too large, which can cause the body to shake at high speeds. Examples:

Under normal circumstances, the front tire pressure is usually the same as the rear tire pressure is about the same. If the tire pressure of the right front wheel is and the pressure of the left rear tire is is, due to the difference in air pressure, the tire's ability to absorb energy and absorb shock is inconsistent, and the body shakes at high speeds.

Severe tire wear: Due to wheel alignment or rim deformation, the tire surface is worn inconsistently, resulting in body vibration during driving.

2. The car needs to do dynamic balance or four-wheel alignment, note: dynamic balance and four-wheel alignment are two different.

Dynamic balance: After tire repair, wheel rim deformation, abnormal tire wear, tire piercing big nails or entrainment of large stones, etc., will destroy the tire dynamic balance.

Four-wheel alignment: The wheel alignment data has a large deviation. In particular, the positioning angle of the front wheels is out of alignment, and the toe is too large. In this case, it feels that the vehicle is difficult to control when accelerating, and the shaking is generally not large, but it is awkward.

3. Problems with the engine.

Generally, it is caused by oil or ignition, and the vehicle is under high speed and high load, and the oil and ignition determine the power, and if one of the points is abnormal, it will cause the engine to shake weakly.

To sum up: it is recommended that the owner should go to the 4S shop or auto repair shop in time to let the car repair master test the vehicle and determine where the problem is, so as to repair the symptoms.

If there is a slight shaking or deviation of the body during driving, it is generally caused by the fault. First of all, it may be that the tire balance is not good, and the owner needs to do a four-wheel alignment and dynamic balance as soon as possible.

The other condition is more serious, which may be caused by the deformation of the steel rim, which requires the owner to go to a professional repair shop for inspection. This condition usually occurs in vehicles that are more than a year old. Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance, otherwise the steering wheel will be prone to shake when the counterweight is uneven.

Body shake will have an impact on driving comfort and handling judgment.

The third situation is caused by the unbalanced deformation of the transmission shaft, which generally occurs in the chassis collision of more cars.

Problems with the ignition system are also one of the reasons for the vehicle shaking, when there is a problem with the spark plug, high-voltage wire or ignition coil in the ignition system, the car will also be shaken when starting, and the owner can judge the cause of the vehicle's idle jitter by checking the spark plug.

3. Unstable oil pressure

When the data of the oil supply pressure of the automobile oil pump is inaccurate, the vehicle will also shake when idling, check the oil pressure, and deal with it in time if it needs to be replaced to avoid causing greater failures.

The most common fault of jitter during driving is that the spark plug is damaged, the spark plug pole gap wear leads to insufficient ignition of the spark plug, the mixture is not fully burned and causes the spark plug to shake during acceleration, and there is a crack in the ceramic part of the spark plug, which causes the spark plug not to ignite, and a cylinder that does not work will also lead to acceleration jitter.

The quality of gasoline is not good, resulting in the poor atomization effect of the fuel injector, and the mixture is not fully burned in the cylinder, so it will also lead to idle shaking.

The most common fault of shaking while driving is that the tread of the four-wheel tires has uneven faults, such as bulging and foreign objects. In addition, the loose bearings of the wheels will also cause the moving vehicle to shake.

After using the vehicle for a while, the shaking seems to be getting stronger and stronger, but I don't think it will affect safe driving, so I ignore it. What many car owners don't know is that the body shake is a data signal that the vehicle informs the owner of something wrong with a certain location. If not handled properly, it will obviously endanger safe driving, and should be inspected or repaired immediately.

Many car owners notice unusual shaking at the start. This type of jitter is called high-speed jitter. The primary factor leading to this problem is that the engine carbon deposition is relatively serious, some parts of the automobile engine are aging, and the oil pressure is unstable.

If there is any problem with the ignition device, the quality of the oil added is very poor, and you feel abnormal, please go to the repair shop immediately for inspection. I firmly believe that everyone is aware that adverse effects can be fatal anytime, anywhere. The importance of safe driving safety is obvious.

There are many horrific examples that warn everyone to pay attention to safety when entering the car.

When driving, be sure to concentrate on the essence of your mind and not have to wander your mind. Don't do it for two things while driving. When a car is driving at a rate of 60 kilometers per hour, if the owner has seen a short message, it is likely that the car has already traveled about 30 meters, which is enough to make everything happen.

When driving, don't or try not to do anything else that is not related to driving. If you're unhappy, you're better off not having to drive or manage yourself as much as possible. Stay awake while driving.

If you are too tired and want to sleep at night, you don't have to drive as much as possible. It is not necessary to drive while drunk. Ethanol or some pharmaceuticals can delay the speed of time reaction, jeopardizing discrimination and coordination.

Speeding is the most common and most likely to lead to serious road accidents. It will make the driver's vision smaller, the eye's vision will be weakened, the reflection distance will increase, and there will be no effect on the risk of the front. The braking deceleration of the car is mainly limited by the speed per hour.

Because of the effect of inertial force, the faster the speed, the greater the braking deceleration, which in turn increases the probability of safety accidents. A motor vehicle driver's license is a reasonable, legal and valid document that allows motor vehicles to drive on the road in China. The driver's license consists of three parts, the name of the driver's license folder, the main page and the sub-pages.
