What is the reason for the frustration when the car accelerates?

The reasons for the frustration of acceleration are:

1. The acceleration and shaking of the car is inseparable from the problems of the engine oil circuit, ignition, and air intake systems, which may be due to the fact that there is sludge in the transmission oil circulating in the gearbox and blocking the oil passage in the valve body, which will lead to a series of gearbox problems such as high temperature, impact, and slippage of the gearbox for a long time;

2. First of all, you should do some simple checks, such as whether you add the wrong oil, which is also possible, because if you add low-grade gasoline, there may be a situation of weak acceleration, resulting in a decrease in engine power and an increase in fuel consumption;

3. Then the engine oil circuit system, the importance of engine oil is needless to say, it can fully lubricate, reduce resonance, and improve the smoothness of engine operation. 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, gasoline pump failure and fuel filter blockage will also cause engine power to decrease;

4. Then there is the intake system of the engine, in addition to the engine needs oil, it also needs air, 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, if the ignition of the spark plug is poor, dripping or atomizing, it will also affect the engine acceleration;

5. In addition, the problem can be judged 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 may be due to a lack of cylinder, which is most likely caused by a malfunction of the ignition system. Lack of cylinder means that one cylinder of the engine does not work, which will lead to a decrease in the smooth operation of the engine and a lack of power.

The main components of the engine ignition system include the ignition coil and the spark plug.

A spark plug is a wear piece that needs to be replaced regularly, and the electrode gap of the spark plug will increase over time.

If the electrode gap becomes larger, the ignition energy of the spark plug will be reduced, and if the ignition energy is reduced, the combustible mixture in the engine will not be fully combusted, which will lead to a decrease in power and an increase in fuel consumption in the engine.

If the spark plug is not replaced for a long time, it may directly cause the spark plug to fail to ignite, the ignition coil is directly connected to the spark plug, and the function of the ignition coil is to increase the voltage.

Only with a sufficiently high voltage spark plug can there be sufficient ignition energy.

Although the ignition coil is not a wearing part that needs to be replaced regularly, the ignition coil is also very prone to failure when operating in a high-temperature environment for a long time.

If the ignition coil is damaged, the spark plug will not ignite, which will directly lead to the engine missing cylinders.

Reasons for the sudden acceleration of the car:1. There is more carbon deposition in the throttle, fuel injector and inlet tract. There are many failures caused by carbon deposits, and some vehicles will have a sense of frustration is also related to carbon deposits, so it is recommended to pay attention to cleaning up carbon deposits.

2. The fuel quality is unqualified and the combustion is insufficient.

Some of the frustration caused by stepping on the accelerator is a normal phenomenon, and some are due to car failure, which should be investigated in time. It is normal to step on the accelerator to produce frustration: For manual transmission models, in the semi-clutch state of driving, refueling and oil collection will produce frustration, and the deeper the throttle is pressed, the greater the frustration.

When the car accelerates, the frustration is not smooth, and the auto mechanic has repaired the car for many years and shares the cause of the failure! by: Chen Gong chats about cars.

Generally speaking, too much carbon deposition in the car engine and problems such as car transmission failure will lead to a sharp acceleration of the car, so it is recommended to find a regular auto repair shop for good maintenance.

The first car frustrated the main bai if it was du

engine and clutch construction.

In this case, the car DAO acceleration is powerless to a certain version.

It has a lot to do with the power of the engine, and the ignition, air intake, and fuel injector jointly determine the combustion of fuel, which is also the power of the engine. Then the acceleration weakness is naturally related to the ignition, air intake, and fuel injector systems.

If there is a frustration in the acceleration of the car, the owner can first conduct a simple inspection of the vehicle, such as checking the amount of oil, whether the engine throttle, fuel injector, spark plug, three-way catalytic converter and other parts have not been maintained for a long time, usually these parts will produce carbon deposits after a long time, which will affect the power of the car.

And frustration, more factors are due to the clutch, theoretically speaking, in addition to the CVT gearbox, other gearboxes will have frustration, CVT gearbox is also known as continuously variable gearbox, as the name suggests, for CVT there is no concept of gear, so CVT naturally will not exist shift frustration. However, in fact, due to the manufacturer's tuning, even the continuously variable gearbox may have a sense of frustration.

And there is a frustration in acceleration, mostly because the corresponding speed of the gearbox is not fast enough, and the upshift speed can't keep up with the speed at which you step on the accelerator, so the moment the gearbox shifts, the frustration comes.

In addition to these, there may also be problems with the gearbox gear program, dirt and impurities inside the gearbox, and heat dissipation problems in the gearbox.

CS75 acceleration on the accelerator will feel the car has a sense of frustration, if the car is driving more than 30,000 kilometers, I personally think that it may be caused by too much carbon deposition in the car engine, it is recommended to check whether the spark plug of the car needs to be replaced, whether the throttle needs to be cleaned.

The frustration when accelerating may be due to a design problem with the gearbox itself, or the engine has too much carbon deposit, and the engine is missing cylinders.

1. Check the throttle.

2. Check the fuel injector.

3. Check the air intake.

4. Check the spark plugs.

5. The main reasons for checking the ignition coil: 1. Long-term short-distance driving, 2. The quality of air and oil is not good, and 3. The car has been running for a long time.

1. The throttle and clutch are not well coordinated.

2. The gasoline pump is faulty, and the fuel filter balance is blocked.

3. The air filter and throttle are blocked.

4. Poor ignition, dripping or atomization of spark plugs.

5. The gasoline label is unqualified.

6. The solenoid valve is damaged.

1. The speed of the clutch input and output should be the same every time the gear is shifted.

2. Check the throttle valve, fuel injector, inlet spark plug, and check whether the ignition coil is damaged.

3. When the clutch is in semi-linkage state, let the engine and the Changshu gearbox rotate at the same speed.

The reasons are as follows:1. The fuel supply system of the motor vehicle is not smooth, and it is necessary to clean the oil circuit, clean the oil nozzle, replace the gasoline filter and cleaner, and use high-grade fuel.

2.Carbon deposits occurred in the engine's internal air intake system, requiring the replacement of the air filter element and the cleaning of the intake pipe and throttle valve. There is a sense of frustration when a motor vehicle accelerates during normal driving.

Check the oil circuit of the motor vehicle and check the engine of the motor vehicle at the same time. After finding out the cause of the failure, symptomatic repair. After maintenance, the driving state of the motor vehicle will return to normal and will not affect the future use of the motor vehicle.

The oil circuit is blocked. 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.

After the automatic transmission vehicle starts, if you want to drive smoothly, you can lightly press the accelerator pedal at the right time, and the transmission will move up the gear from the old hail chain, and the frustration of shifting at this time is weak; If you want to maintain good acceleration, you need to press the accelerator pedal deeply, and the automatic transmission will move up to a higher gear at higher speeds, where the shift pause is more 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 to form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation impact and slippage. At the same time, the problem of high temperature of the gearbox cannot be ignored. High temperatures can damage the quality and friction characteristics of automatic transmission fluids, increase friction and wear, and transmission noise will follow, as well as sludge (impurities or dirt) will also be generated inside the transmission (e.g. valve body), resulting in transmission setbacks and shocks.

If the temperature exceeds 120 °C, the rubber seal will begin to harden, eventually leading to leakage and reduced hydraulic pressure. If the temperature is higher, the gearbox starts to slip, which in turn causes the temperature to rise even higher. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

There are three reasons for this, namely:

1. There is more carbon deposition in the throttle, fuel injector and inlet tract.

There are many faults caused by carbon deposits, and some cars will have a sense of frustration due to carbon deposits, so it is recommended to pay attention to cleaning up carbon deposits.

2. The fuel quality is unqualified and the combustion is insufficient.

The car and the land shoot quickly have a frustration of excessive moisture in the fuel, the oil circuit is blocked, and the fuel pressure is unstable, and the automatic transmission of the vehicle may be caused by the failure of the shift solenoid valve.

Once you've discovered the problem, you can do some initial checks to determine if the wrong fuel has been added. If you always use high-grade fuel and occasionally add low-grade fuel, the power of the crude engine will be reduced and fuel consumption will increase. In addition, if the gasoline pump fails, the fuel filter is clogged, and the engine power will drop.

When there is no problem with the fuel, check the oil circuit system. Engine oil is very important in automobiles, it can be well lubricated, reduce resonance, and improve the smoothness of engine operation. If the engine oil is insufficient, it will affect the increase in electricity consumption; Serious ones will directly damage some mechanical parts.

After that, check the air intake system for faults. In addition to fuel, the engine also requires a certain amount of empty air. If the air filter, throttle and other components are blocked or problematic, the air intake is not used enough, and the fuel combustion is not sufficient, which affects the power.

For a long time, carbon deposits were created due to insufficient fuel combustion. The spark ignition plug in the ignition system cannot be ignored either. If the spark plug leaks or fogs up, it can also affect engine acceleration and stuttering.

There are also some problems that can be judged according to the phenomenon of the car, such as smoke from the exhaust pipe, if there is black smoke, then there are problems with the combustion chamber, ignition system and valves; If there is blue smoke coming out of the exhaust pipe, then it is possible that the oil has run to the combustion chamber, which is also known as burning oil. The frustration of the car when accelerating is closely related to the engine oil circuit, ignition, and air intake. As long as you check them one by one, this problem can always be solved.

Millions of car purchase subsidies.

Inspect the internal valve body of the gearbox for damage. Changing the transmission oil requires 2 years or 40,000 kilometers to change the transmission oil. 2. Cause mold fluid:

Dirt and impurities inside the gearbox, internal dirt or impurities cause the transmission oil pressure to be effectively regulated. Transmission heat dissipation problems: Poor transmission heat dissipation will cause the transmission to be abnormally high temperature, which will affect the performance of the transmission oil, if the temperature exceeds 120, the rubber sealing material of the transmission will become hard, causing the transmission to leak, which will affect the oil pressure and cause frustration.
