What is the reason for the disappearance of the all new Tucson idle jitter acceleration

The main cause of idle jitter;

1. The most common cause of vehicle shaking is that the throttle 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.

Indeed, the phenomenon is similar to yours before, and it will take a while to shake off after starting, and the red light will also shake a little when the hot car is idling. The kilometers are not many and I can't find other problems, and then another car in the family uses Si Youpu to clean the oil road without shaking. I also tried, and after running a tank of fuel, it basically didn't shake.

The accessories have been changed and checked, and the shaking is caused by the long-term use of ethanol fuel and unclean use. Long-term ethanol fuel impurities and moisture in the oil circuit will not burn well, it will shake, ethanol fuel gas stations basically clean the oil storage tank once a month, and underground oil tanks are not considered sealing space. Therefore, it is necessary to clean it regularly, and 9 days is the deterioration period of ethanol fuel.

It seems that this situation is mainly caused by poor combustion inside the engine, and it is recommended that you go to the repair shop to clean the injector and replace the spark plug.

Hello, this situation may be caused by excessive carbon deposits in the engine system, it is recommended to clean up the engine carbon deposits

If the car shakes while driving, it is generally caused by the tire. It may be that the tire has deviated, or it may be that the tire is not well balanced, and the balance of the tire has fallen off. If the vehicle does not deviate and do the tire dynamic balancing, it may also be that the wheel hub has been deformed by external impact, and you need to go to the repair shop to check to know.

The fifth-generation Tucson L brings together five "Tucson L Moments" to lead the way: Stunning Moments (Appearance), Trendy Moments (Space), Technology Moments (Intelligence), Combustion Moments (Performance) and Peace of Mind (Safety).

Stunning moments Create the pinnacle of Tucson series models: The fifth-generation Tucson L is based on the design language of "Sensuous Sportiness" and incorporates the design theme of "Parametric Dynamics", and the overall shape is trendy and avant-garde.

Generally speaking, the phenomenon that causes shaking and shaking during driving is mainly analyzed from two aspects. The first. It is the phenomenon that the engine has a lack of cylinders, resulting in jitter.

On the other hand, it is equipped with automatic transmission models, so there is a possibility that the gearbox will slip when it is working, and the power transmission will be interrupted! It is manifested as a shake when the vehicle is moving forward!

1. Most Tucson is a 7-speed dual-clutch transmission, and this kind of matching may have a slight jitter in the starting or shift gap, which is normal.

2. Tucson has a transmission program recall upgrade, you can contact the local 4S store to confirm whether the upgrade is needed.

3. Excluding the above factors, if the shaking is bad, it is recommended to go to a 4S shop or a professional repair shop for test inspection.

The car idle jitter problem is:

1. Failure of spark plug or ignition coil;

2. The valve timing is incorrect;

3. The cylinder is compressed unevenly;

4. The valve seal is not tight, and the air leaks;

5. Poor fuel pressure; Fuel injector plugging leakage;

6. Leakage between the cooling system and the cylinder;

7. The air flow sensor is faulty.

Workaround for unstable idling:

1. Fault self-diagnosis. Pay special attention to the fault codes of idle switches, coolant temperature sensors, air flow meters, oxygen sensors, and idle control valves. If there is a fault code, the corresponding sensor and control circuit should be checked.

2. When idling, unplug the high-voltage line or injector wiring harness plug of each cylinder one by one, and check whether the cylinders of the engine work evenly. If the engine speed does not drop significantly when unplugging the high-voltage line or injector harness plug of a cylinder, it means that the cylinder is working poorly, and the spark plug and injector of the cylinder should be disassembled.

3. Detect the throttle position sensor, if the idle switch in the throttle position sensor cannot be closed when the throttle is fully closed, the throttle position sensor should be adjusted or replaced from the new.

Fourth, with the car computer detector, you can measure the coolant temperature sensor, if the coolant temperature value transmitted by the coolant temperature sensor to the engine computer is inconsistent with the actual coolant temperature, it means that the coolant temperature sensor is faulty and should be replaced.

5. Check the air flow meter with a computer detector or multimeter or oscilloscope, and replace it if there is any abnormality.

6. During the idle operation of the engine, unplug the wiring harness of the idle valve. If the up and down fluctuations in the idle speed disappear, but the instability of the idle speed increases, the idle control valve is working properly and the injection system is faulty. If the idle fluctuation phenomenon does not change, it means that the idle control valve is working poorly or is not working.

In this regard, the idle control valve harness plug should be checked for pulse electrical signal, if there is no electrical signal, it means that the idle control valve is stuck, and the idle control valve should be dismantled or replaced.

Slight jitter is normal, if the jitter is more severe, you need to check it.

The most common cause of car shake is excessive dirty throttle or excessive carbon accumulation in the fuel injector.

When the carbon deposit inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposit in large quantities, resulting in the mixture of cold start is too thin, making it difficult to start the leakage, in this case, only when the gasoline absorbed by the carbon deposit is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit after the car will be sucked into the sock 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, causing idle shaking after cold start.

Causes of jitter at idle:

1.The engine has serious carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposit inside the engine is too much, the gasoline sprayed out by the cold start fuel injection head will be absorbed by the carbon deposit in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by the carbon deposit is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposit after the car 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, causing idle shaking after cold start.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system and spark plug are not working well, and the poor working condition of the ignition system and spark plug will also lead to this kind of failure.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, replaced the spark plug, etc., and still found that the body shakes when idling, it is recommended to check whether the fuel supply pressure and intake pressure sensor are normal.

Solution; The best way is to clean the oil circuit, clean it regularly, and use PNF fuel additives to solve the problems caused by the above-mentioned accumulation of silver carbon. 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 slurry of the oil circuit, which will continue to pollute the fresh fuel, resulting in no good fuel to participate in the combustion in the later stage, and the carbon deposition exceeds the standard, which is especially common for the National VI car. We can only gradually alleviate most of the problems by maintaining clean oil circuits.

There are many reasons for car jitter, it can be too much carbon accumulation on the throttle, aging engine floor pads, or it can be a lack of cylinders in the engine. The lack of cylinder is caused by a faulty ignition system. The main components of the ignition system include the ignition coil and the spark plug.

Causes of 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 deposition inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by a large amount of carbon deposition, resulting in too thin mixture, making it difficult to start.

After the car is hit, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine for combustion, which will make the mixture thicker. 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 to the problem is to clean the carbon deposits at the throttle and fuel 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.

Tucson Start-Up Jitter Solution: Clean the oil circuit, check the idle motor for carbon deposits, and clean it.

2.As an urban SUV focusing on the young market, the Tucson has a clear silhouette, a combination of rigidity and softness, and the positive lines of the body make the vehicle reveal the taste of European cars, and the short tail creates a young and dynamic overall style.

3.The Tucson will be equipped with a liter CVVT engine and an engine. The CVVT engine uses a continuously variable valve timing system.

The application of this system enables the CVVT engine valves to control the opening and closing of the valves at any time according to the state of the engine. Under the premise of fuel economy, the engine power output is stronger and the fuel combustion is more complete.

Before washing the air intake system with walnut sand, with 3 tanks of Siyoupu fuel additives to wash the oil circuit, I was divided into two times, the first time is the air intake, after the feeling is not so obvious, the second time is to use the Si Youpu fuel additives after the normal driving is also the normal form of the room, the effect is obvious, the car feels strong, the throttle is much lighter, and it is a lot quieter. The third time I washed the piston ring was washed before maintenance, and I also used Si Youpu fuel additives to wash, and the new engine oil was changed after washing, and I felt that the vulgar power was much greater than before. The whole is OK, but the first time I washed the air is expensive, and the remaining two times I got it myself.

According to Bian Xiao, many friends don't know much about some car knowledge. In order to make it easier for everyone to understand this knowledge, today Bian Xiao will tell you about the reason why Tucson began to shake? Interested friends can learn about this problem, which may be helpful to you.

Tucson began to tremble. What caused the shock? The most common cause of car shake is that the throttle is too dirty or the fuel nipple has too much carbon.

When there is too much carbon deposition inside the engine, the gasoline sprayed by the cold start injector will be widely absorbed by the carbon deposition, affecting the cold start mixture, and it is difficult to start. In this case, Bishan is easy to enter the car only when the gasoline adsorbed by carbon deposits reaches saturation, and the gasoline adsorbed on the carbon deposits after entering the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, so that the mixture becomes thicker, and the combustible mixture of the engine becomes thinner and thicker, resulting in idle shaking and shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon is deposited, the more it affects the success of the cold start.

It is inevitable that the engine will produce carbon deposits, but when the engine has too much carbon deposits, it will lead to poor engine work and different problems. When the engine has too much carbon deposit, the gasoline sprayed by the cold start fuel injection head will be widely absorbed by the carbon deposit, which will affect the cold start mixed with the fierce shed gas, and it will be difficult to start. It is not until the gasoline absorbed by carbon deposits is saturated that it is easy to enter the car.

After entering the car, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine to burn, so that the mixture becomes thicker, and the combustible mixture of the engine becomes thinner and thinner, which will cause idle and shaking after cold start. Solution: Clean the oil circuit and check whether the idle motor has carbon deposits, which should be cleaned.
