Why does the car accelerate and rush, and what is the reason why the car rushes and rushes while dri

Hello, this situation may be the cause of excessive carbon deposition on the throttle, you can clean the carbon deposition of the throttle.

This is generally the reason for the blockage of the fuel injector, cleaning the throttle and fuel injector, and replacing the spark plug, the effect is better.

It's not a big problem, don't worry.

Focus on checking the fuel system (gasoline part: gasoline quality, gasoline filter, fuel injector, air intake system: air grid, throttle, intake duct, combustion part: combustion chamber, three-way catalysis).

Cleaning method: Go to a regular or large one-stop enterprise for fuel dismantling and cleaning, and the company will clean the gasoline section and air section, which can effectively eliminate the fault of your car.

In addition, after the above maintenance, the next match is performed. At the same time, check the high-voltage cables, spark plugs, and clutch parts (cables, clutch plates, etc.) of the car.

According to this idea, you will definitely be able to eliminate the problem, please rest assured, I hope it will help you.

Because the vehicle has too much low carbon, you can clean the throttle and fuel injector to check the working condition of the spark plug.

The main reason for the acceleration of the car is that the throttle has too much carbon and too many fuel injectors, so it is recommended that you go to a local repair shop to clean it.

If it is a manual transmission vehicle, it may not match the speed and gear. It is also possible that the vehicle has too much carbon.

If it's a manual transmission vehicle, it's possible that your gear doesn't match the speed. If it's not for this reason, it could be lightweight sighing loneliness.

If the car accelerates and rushes, it means that the oil circuit may be poor, and it may also be caused by oil problems.

Hello, in this case, you should check the fuel injector, clean the throttle to see if the carbon deposit is serious, and go to the repair shop to check it.

If this acceleration is unstable, it is usually either a dual-clutch gearbox or a carbon deposit on the engine throttle.

If the oil supply is not available, clean the carbon deposits on the throttle and the fuel injector, the spark plug is aging, and the ignition coil has problems will also cause this problem.

Hello, in this case, it may be caused by foreign matter in the throttle, check to see if there is too much carbon deposit, and clean up the foreign body in time.

In this case, it is recommended to check the throttle to see if the charge is blocked, whether there is a problem with the spark plug, you can check it and see.

Hello, is this an inch faster?So that's the speed, and the reason why the motivation can't keep up.

Hello, in this case, it is recommended to clean the throttle and fuel injector, the cost is not high, and there will be a significant improvement.

The reasons for the pause during the driving of the car are: the first is the insufficient ignition of the spark plug caused by the wear of the spark plug pole clearance; The second is that the quality of the added fuel is not good, which leads to the poor atomization effect of the fuel injector, so that the mixture is not fully burned in the cylinder.

The main function of the spark plug, commonly known as the nozzle, is to introduce high-voltage electricity into the combustion chamber, and at the same time generate an electric spark to ignite the mixture, so as to cooperate with the ignition system and the oil supply system to make the engine work, and the combined effect of the three largely determines the performance of the engine. The service life of spark plugs of different materials is also different, from high to low, it can generally be divided into: the service life of imported double iridium spark plugs is 100,000 kilometers, the service life of imported iridium platinum spark plugs is 80,000 kilometers, the use of imported platinum spark plugs is 3-50,000 kilometers, the service life of imported iridium spark plugs is 3-40,000 kilometers, the service life of imported nickel alloy spark plugs is 2-30,000 kilometers, and the service life of domestic nickel alloy spark plugs is 10,000 kilometers.

Regarding the replacement cycle of spark plugs, the maintenance cycle specified by the manufacturer of different models of cars is different, so the specific replacement cycle should be subject to the requirements of the automobile manufacturer.

Hello 1The most common fault is that the spark plug is damaged, the spark plug pole gap is worn and the spark plug ignition is insufficient, the mixture is not fully burned and the acceleration is shaking, 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 cause 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.

This problem should be detected with a diagnostic instrument, which may be the cause of a cylinder fire failure (spark plug or ignition coil, etc.).

Car frustration is unavoidable, this manual transmission owner knows that if the accelerator and clutch do not cooperate well when changing gears, the vehicle will have a significant sudden deceleration and sudden acceleration, which is the most obvious "frustration".

However, in automatic transmission, because the shift control is carried out by the computer, theoretically it will be smarter, but due to the structure of the transmission, in the automatic transmission model, the frustration is also different.

If you exclude the frustration of the car under normal conditions.

First of all, you can do some simple checks yourself, such as whether you have added the wrong oil, which is also possible, because adding low-grade gasoline may cause weak acceleration, resulting in a decrease in engine power and an increase in fuel consumption.

Then there is the engine oil system, which is not only important because it can be fully lubricated, but also reduce resonance and improve the smooth operation of the engine. If the engine oil is insufficient for a long time, the light one will have insufficient power and the fuel consumption will increase; In the heavier case, the piston strikes the door, causing mechanical damage to the associated connectors. In addition, a faulty gasoline pump and a clogged fuel filter can also cause a drop in engine power.

Then there is the intake system of the engine, the engine needs air in addition to oil, if the air filter, throttle and other components are blocked or there are problems, resulting in insufficient air intake, it will also cause the car to accelerate weakly and slowly, and there is a sense of frustration. The ignition system is also not negligible, and if the spark plug ignition, leakage or atomization is poor, it will also affect the engine acceleration.

In addition, we can judge that there is a problem according to the symptoms that the car is also accompanied by, such as smoke from the exhaust pipe, if there is black smoke, then there is a problem with the combustion chamber, ignition system, and valve; If there is blue smoke coming out of the exhaust pipe, then it is possible that the engine oil has run to the combustion chamber, which is what we call burning the engine oil.

This phenomenon is called vehicle rushing. It refers to the intermittent slamming phenomenon of the vehicle during starting and low-speed driving. The damage to the power system and transmission system of the vehicle is relatively large. This driving operation is also unqualified.

1. Solution:

Check whether the fire spoil plug has creepage, and it is recommended to replace the spark plug (if there is a cylinder wire, it is recommended to replace the cylinder wire together) should be able to eliminate the fault. Or check the oil circuit or ignition cause, find a repair shop or 4S shop to continue to check and repair!

Second, the reasons for the break-in are:

1. The throttle is too large, and the engine speed is too high;

2. The speed of the vehicle is too slow;

3. The clutch is loosened too quickly.

3. Precautions.

When starting, pay attention to the throttle not to be too large, even without stepping on the accelerator to idle the start, and the clutch should not be loosened too fast. Crashing while changing gears is the result that the driver is not skilled enough to find the point between the throttle and the speed. Causing the throttle to be too large when the clutch is loosened.

The solution is to loosen the throttle properly when changing gears and find the right fit.

The easiest way to eliminate it is to clean the throttle once, and if it doesn't work, you have to go to the repair shop to check. 1. Diagnosis method for idle switch not closing: turn on the air conditioner when idling, and turn on the steering wheel The engine speed does not rise, which can prove to be this fault.

Troubleshooting: Adjust, repair, or replace the throttle position sensor. 2. Idle control valve (ISC) fault diagnosis party.

There are many reasons for this phenomenon, and it is best to go to a 4S store to check. Problems with the car's air intake system, oil circuit, ignition system, valve, gearbox, etc., will cause the car to rush when refueling the valve. If this phenomenon occurs, coupled with the abnormal color of the vehicle's exhaust, then there is a problem with the engine and you need to go to the 4S shop for inspection in time.

There are many reasons for this phenomenon, and it is best to go to a 4S store to check.

If this phenomenon occurs, coupled with the abnormal color of the vehicle's exhaust, then there is a problem with the engine and you need to go to the 4S shop for inspection in time.

Computers in modern vehicles are very advanced. If there is a fault in a certain part of the vehicle, the fault can be read by a diagnostic computer** for the convenience of maintenance personnel. And there are a lot of sensors on modern vehicles, and these sensors are prone to failure, which can lead to abnormal working conditions of the vehicle.

Today's automobiles are generally equipped with variable valve timing and variable valve lift systems. If there is a problem with this system, the speed of the vehicle will not go up and the fuel consumption will increase. When there is a problem with the gearbox, it does not work well with the engine, which will cause the vehicle to accelerate sharply.

Abnormal internal combustion of the engine can also cause the car to be in a hurry. There are pistons, valves, spark plugs in the combustion chamber, and in some cars there are fuel injectors. Any abnormality in these components will lead to abnormal combustion of the engine. It is recommended that the owner of this fault phenomenon go to the 4S shop for maintenance.

There are many reasons for this, it can be a problem with the oil supply system, ignition system, or air intake system.

Currently, all cars use electronic throttle. When you press the accelerator pedal, the throttle opening will become larger, and more air will enter the engine. As the amount of air entering the engine increases, so does the amount of fuel injected, so that the engine speed rises and the car accelerates.

If there is a problem with the throttle, the throttle opening does not increase after pressing the accelerator pedal, and you will feel bored and lose fuel when accelerating.

The normal operation of a car's engine is inseparable from the fuel supply system. If there is a problem with the gas pump or injector, there is no more fuel injection when more fuel is needed, and the car will not be able to accelerate after pressing the accelerator.

The ignition system mainly consists of a spark plug and an ignition coil. If the ignition system does not work well, it will lead to insufficient combustion of the combustible mixture in the cylinder, which will make the engine stuffy. If the spark plug or ignition coil of one cylinder is broken, one cylinder of the engine may stop working, causing the engine to stuff and shake abnormally.

1. The oil circuit is blocked, clean the oil circuit, fuel injector, oil circuit and oil pipe.

2. When the automatic car starts, there is a normal situation of frustration. If you want to accelerate sharply while driving, you need to step on the accelerator deeply, then the automatic transmission will automatically reduce the gear to increase the engine speed, and then upshift when the speed reaches a certain height.

This situation is more likely to occur in automatic transmission models with fewer gears, such as those with 4th automatic gears. If you want to drive smoothly after the automatic transmission starts, you can gently press the accelerator pedal at the right time, and the transmission will automatically upshift, and the shift will be less frustrating.

3. Automatic start-stop and dual-clutch gearbox have this problem in itself.

4. If the ignition is abnormal, replace the spark plug or high-pressure bag.

5. In many cases, it is not the internal valve body that is damaged, but the stubborn dirt and impurities inside, especially in the internal valve body, the dirty impurities accumulate and the hole is blocked, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation impact slippage.

Manual transmission car operation essentials.

There are three essentials of clutch operation: one fast, two slow, and three linkage. When lifting the clutch pedal, it is necessary to follow the operating principle of "one fast, two slow, and three linkage". When starting, press the clutch pedal to move neatly, one foot to the end, so that the clutch is completely disengaged.

The so-called "one fast, two slow, three linkage" is the process of clutch pedal lifting is divided into three stages, at the beginning of the fast lift, and dry when feeling the clutch pressure plate gradually combined to semi-linkage, the speed of pedal lifting began to slow down, in the process of semi-linkage to full integration, the clutch pedal is slowly lifted.

When the clutch pedal is raised, the accelerator pedal should be gradually pressed down according to the size of the engine power, so that the car can start smoothly. The throttle should be operated smoothly and properly, and the throttle should only be increased when the clutch is fully engaged.

Summary. Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am a car master maintenance technician According to your question 1, there is a problem with the spark plug, 2. The ignition coil is not normal, depending on how many yards you have, there is a low-speed ignition coil, and a spark plug is in the high-speed pie.

When you increase the throttle, you will rush and rush, and there is no problem with slow acceleration.

How many kilometers of the car, take a look at the above two situations.

Freshly replaced spark plugs.

54,000 km.

It depends on whether your speed is above or below 80 yards, and if you are below 80 yards, there is no ignition coil problem.

This is the case with sharp acceleration after gear engagement.

Then just start it should be no ignition coil problem, you need to try one by one, this situation is not faulty.

Sharp acceleration after shifting gears is still a problem.

The ignition coil and the spark plug are not the same thing.

There is no problem with 1st and 2nd gear, and this problem will occur above 3rd gear.

Yes, there is no problem with the ignition coil, and you need to buy a new one from the beginning of the exchange to which cylinder is not the problem of the ignition coil of this cylinder.
