What is the solution to car jitter?

Now every family has one or two cars. So when we are driving a car, we will pay special attention to some problems of the car itself. Then if we don't notice, there is a chance that we will be in some danger when we are driving a car.

At the same time, we will also send our cars to the car maintenance station regularly for some maintenance and some inspections, so what we are going to talk about today is when we are driving a car, suddenly find that the car is a little shaky, so how to solve this situation?

The first thing to clean the grease is to clean the grease and check whether there is carbon deposit in its idle motor. If the car shakes, it should be the engine with serious carbon deposits, so the most common cause of car shake is this. If the throttle is too dirty or there is too much carbon on the nozzle, the gasoline adsorbed on the engine will be sucked into the cylinder and then burned, so the engine will mix some gas at this time.

Sometimes the weather is too cold, which will make the car shake rapidly.

The second thing to do is to check whether the spark plug has too much carbon, so we also need to replace the spark plug if necessary. One of the causes of car jitter is that the car will shake when the spark plug, high-voltage wire or ignition coil is not working well. In this case, the solution is actually very simple.

Just send the car to the car service station and replace a spark plug, which can solve this problem very well.

Replace some parts, then in the end, we need to replace some parts of the car, because the car sometimes shakes, and it is also related to the aging of some parts of the car. Then we need to go to the car repair station for some maintenance, because we don't know which part of the car has a problem. Vibrations like these will be transmitted to the steering wheel and the cab, if we don't know exactly which part is wrong.

It will pose a very big threat to us, and even cause major traffic accidents.

The main cause of idle jitter;

1. The most common cause of car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

2. When the carbon deposition inside the engine is too much, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon deposition, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get started, 3. After the car is adsorbed, the gasoline adsorbed on the carbon deposition will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, resulting in idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Severe idle vibration is generally caused by engine cylinder failure, aging or loose foot rubber, carbon deposits, fuel system failure, etc.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the above problems caused by carbon deposits. The fuel quality is not very good or the initial fuel of the new car 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, and the carbon deposition exceeds the standard, which is especially common for China VI vehicles. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

If the car shakes during driving, you must pull over immediately, it is likely that the idle motor has carbon deposits, and you can clean up the dirt, or it may be that the spark plug is damaged, just replace a spark plug.

Replacing the ignition coil, replacing the foot glue, replacing the spark plug, replacing the intake pressure sensor, replacing the air filter, replacing the fuel injector, etc., these are all good solutions and very easy to use.

This is caused by an imbalance of the wheels, and it is also very convenient to go to a repair shop to replace the wheels, or find someone to replace the tires. If the engine is missing cylinders, it is necessary to find someone to repair it.

In such a situation, we should find out the cause in time, and then carry out targeted maintenance, and we should also consider whether there is a problem with the automatic system, and we should also understand the situation of the engine in time, and we should also consider whether it is caused by the mismatch between the speed and gear.

In such a situation, we can turn off the engine first, and then observe the problem first, and at the same time we can also go to the 4S shop or repair shop for repair, weight problems, so as not to cause serious impact, resulting in traffic accidents.

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 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.

Analysis of the original circle of automobile jitter:

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 car must be balanced once when replacing 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 too high idle speed, and the carbon deposit generated by the engine in the 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.

Professionals tell us that the body body is shaking like a trivial matter, but if you don't pay attention to detection, it will cause a big fault hidden danger. So, what is the problem that causes the body to shake? How should the owner of the Putang World Rolling Pass judge and solve?

There are several reasons for engine shake:

1. The engine has serious carbon deposits, and the most common car with serious shake is that the fuel injector throttle valve is too dirty or too much carbon;

2. Ignition system problems, check the working conditions of spark plugs, high-voltage wires and ignition coils;

3. The oil pressure is unstable, if the first pressure of the pump is abnormal or the error and poor work of the inlet pressure sensor will cause the body to shake;

4. Aging of engine parts; Excessive carbon deposits in engine emissions absorb carbon from the gasoline of the cold-start injector, which leads to a dilute cold-start mixture and difficulty starting.

Specific solutions to idle jitter:

1. The engine has serious carbon deposits. The most common cause of idle judder is excessive carbon build-up on the throttle or injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by the carbon deposit, resulting in a mixture that is too thin and 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; 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.

1. Ignition system failure: It is usually the jitter caused by the aging of the ignition coil and spark plug, which can be replaced.

2. Blockage of oil pipe and fuel injector: If the pressure of the fuel pipe is too low, the fuel pipe is blocked, and the fuel injector is blocked, the solution is to clean the oil circuit.

3. High-voltage line failure: Usually the fault is caused by short circuit and open circuit of the high-voltage line, which will affect the ignition performance of the engine, make the engine shake, and overhaul the high-voltage line.

4. Oil pump failure: The oil pump failure leads to insufficient oil supply, so that the fuel delivered to the engine is too small, and the combustible mixture is too thin and the combustion is not sufficient, resulting in shaking, and the solution is to overhaul the oil pump.

5. Dirty air filter: Dirty air filter will cause too little fresh air to be inhaled into the engine, resulting in insufficient combustion of the combustible mixture, resulting in shaking, which can be solved by replacing the air filter.

6. Excessive carbon deposition in the engine: too much carbon deposition will lead to poor atomization effect of gasoline, which will increase fuel consumption and shake the engine, and it is enough to clean the carbon deposition.

7. Aging of the tripod: The tripod is equivalent to the shock absorption of the engine, and plays a role in supporting the engine.

Under normal circumstances, the shaking of the car engine should be smooth and regular. If you can clearly feel that the car has been shaking recently or has persistent symptoms, then you should pay attention to maintenance, and there are generally four major reasons for engine shake.

Reason 1: Engine Lack of Cylinder Engine Lack of cylinder mainly refers to the engine has one or more cylinders that do not work normally, which is generally manifested as: the exhaust gas flow of the car has obvious intermittent intermittent results, and the exhaust pipe shakes violently, and the engine shakes obviously, sometimes accompanied by a sudden sound.

This is mostly related to ignition coil failure.

Reason 2: The aging or loosening of the foot glue is the rubber block between the engine and the frame. Its function is to reduce the vibration and cushioning of the engine when working, and to have the effect of fixing the engine.

Once these feet are aged or loose, the engine shakes dramatically. The effect will be much weaker after this re-replacement of the foot glue.

Reason 3: carbon deposition problem car is always inevitable carbon deposition problem, the carbon deposition here includes cylinder carbon deposition, throttle carbon deposition, spark plug carbon deposition, intake carbon deposition, etc., when the engine internal carbon deposition is excessive, the ignition energy, intake efficiency, and mixture ratio of the car will be affected, resulting in the unstable power output of the car, and the phenomenon of jitter will occur at idle speed and acceleration. This is recommended to go to the 4S shop for the engine cleaning project.

Reason 4: Fuel system failure adds an inappropriate fuel label (for example, 93 to 90), resulting in a decrease in the output power of the car and a decrease in power; Or due to the blockage of the vent hole of the fuel tank cap, the fuel tank switch, the fuel filter and the oil pipe between the fuel tank and the carburetor are partially blocked, which cannot meet the required oil volume, resulting in the mixture being too thin and the engine shaking.
