It was not normal for a CVR to have a sense of hesitation when adding fuel to the accelerator at low speeds. This could be caused by the following reasons: 1. In terms of the engine power supply system, if there was a problem with the spark plug and ignition coil, resulting in poor high-voltage spark, it would cause the engine to work intermittently and cause a sense of frustration. 2. In the engine fuel supply system, when the fuel injection was blocked or not properly sprayed, the fuel injection was not normal and there might be a setback. 3. As for the transmission, if the valve body was damaged, the transmission oil became dirty, or there were impurities inside, it would cause problems such as frustration, impact, and slipping. 4. The engine foot pad and the transmission foot pad were damaged and could not act as a buffer. There would also be a pause when the accelerator was applied. 5. If the throttle was not cleaned for a long time, too much carbon would be deposited, causing the opening angle of the throttle to change, which would also cause a sense of frustration.

Although the CTV transmission did not have a fixed transmission ratio and did not involve shifting gears, there was almost no sense of frustration when driving under normal circumstances. However, under certain circumstances, there would be a sense of frustration when the accelerator was added. First, due to the fluctuation of the engine's torgue, the vehicle might falter when the accelerator was stepped on. Secondly, some Japanese CVs were unable to react when suddenly refuelling or decelerating due to insufficient strength of the steel belt and steel chain or the problem of the hydraulic moment. There would be serious downshifts, low-speed pauses, acceleration delays, etc. When it was cold, there was also the phenomenon of low temperature protection and sudden refuelling. If it was a chain fault, it might even break. For example, the Jetk CTV transmission under the Japanese company, although nominally able to carry large amounts of power, its reliability and durability were not as good as the AT transmission. In actual vehicle use, such as some mainstream high-efficiency SUVs of Japanese brands, if the owner's driving habits were aggressive, the steel belt and steel chain inside the CVS would easily break. Some popular joint venture cars also had problems with their CVs. For example, it was common for the steel belt of the 9th generation and a half Accord's CVS infinitely variable transmission to break over 15 kilometers. Taking the Teana as an example, when the 2.0T version of the Teana was stuck in a traffic jam at a low speed, it would occasionally feel a sense of frustration when it loosened the accelerator and stepped on the accelerator. When driving at a speed of 30 - 45km/h, it was also likely to feel a sense of frustration when it loosened the accelerator and stepped on the accelerator. In addition, the Audi A4 was equipped with the 0AWCTV CVS continuously variable transmission. If the transmission oil was not changed regularly, the internal filter would be blocked by dirty things and affect the oil flow, resulting in a decrease in the internal grease pressure, which would also cause the starting to be sluggish and the fuel to be weak.

Theoretically, the CTV transmission could achieve continuous changes in the transmission ratio, so there was almost no shift feeling. The driving process should be smoother, but in reality, it was normal for the CTV to have a sense of hesitation when adding the accelerator. From the perspective of the engine power supply system, if there was a problem with the spark plug and ignition coil, it would cause the high-voltage spark to fail, causing the engine to work intermittently, causing a sense of frustration. In terms of the engine fuel supply system, there may be a setback when the fuel injection is abnormal due to carbon deposits, blockage, or poor fogging of the fuel injection. From the perspective of the transmission, if the internal grease pressure drops, there will be a setback in starting and a lack of fuel. If the valve body is damaged, the transmission oil becomes dirty or there are impurities inside, and the oil pressure cannot be effectively adjusted, it will also cause a sense of setback. Moreover, because CVS can continuously change the transmission ratio, when the accelerator is stepped on to refuel, the fluctuation of the engine's torgue will also cause the vehicle to have a setback. The engine foot pad and the transmission foot pad were damaged and could not play a buffer role, or the throttle valve was not cleaned for a long time, resulting in too much carbon deposit, resulting in a change in the opening angle of the throttle valve, which may also cause a sense of frustration when adding the accelerator. In addition, in some small-displacement cars, the CVS transmission may have a rapid increase in the floor oil speed, but the speed would have to wait a few seconds before it slowly increased. This may also be seen as a sense of frustration. Therefore, the feeling of stopping when the CVS stepped on the accelerator could be caused by a variety of factors. Some situations were normal, but some situations might mean that the vehicle was faulty and needed further inspection. The novel " Watching the Moon on Fish Island " is equally exciting.

The strong feeling of CVS downshifting may be caused by the following reasons: 1. ** Insufficient oil pressure or poor oil quality **: CVs rely on the hydraulic system to control the connection and separation of gears. If the oil pressure is insufficient or the oil quality is poor, the efficiency of the hydraulic system will be reduced, affecting the performance of the CVS, resulting in a sudden downshift. 2. ** Worn belt **: The transmission belt is the main component of the CVS. When it is seriously worn, it may cause a sense of hesitation during the engagement process. 3. ** Control unit malfunction **: The control unit is responsible for receiving operation instructions and controlling the work of the hydraulic system. A malfunction will reduce the efficiency of the CVS, resulting in a sense of frustration when downshifting. 4. ** Driving habit problem **: The driver's frequent acceleration and deceleration may cause the CTV hydraulic system to fail to respond in time, resulting in a delay in downshifting. It was suggested to change the oil, check the transmission belt, repair the control unit, and improve driving habits to solve the problem of CVS's frustration when downshifting.

Theoretically, CVs were infinitely variable transmissions. Power transmission was achieved through two cone wheels and a steel belt. The continuous change of the cone wheels allowed the speed ratio to be infinitely adjusted within a certain range. Therefore, under normal circumstances, CVs would not produce a sense of hesitation when shifting gears like the AT and the DG. However, due to insufficient strength of the steel belt or problems with the hydraulic torque-changer, some Japanese CVs might not be able to react in time when suddenly refilling or suddenly decelerating. As a result, there would be serious downshifts, low-speed pauses, acceleration delays, and other phenomena. Some CVs had low temperature protection when it was cold, and they would not go when they were refueled. In addition, if the CVS program was not well defined, when the vehicle slid, it would not be able to cut off the connection between the engine and the wheels in time, which would also cause a similar feeling of stagnation. There were also some CVS models that had problems with the steel belts and chains as they were used for a longer period of time, increased driving range, and aggressive driving habits.

There were the following reasons for the setback of the CVS transmission: 1. ** Steel belt related issues **: - The CTV transmission was driven by steel belt friction. In order to ensure that the steel belt did not slip when shifting gears, the input shaft and the output shaft had a speed ratio requirement. When the speed ratio was abnormal, the oil cylinder would clamp the steel belt. During the process of shifting gears, due to the calculation of the electromagnetic valve and the lag of the oil pressure, the speed of the steel belt would change from slipping to not slipping, resulting in a slight setback, which was the so-called rush. 2. ** Transmission oil **: - If the transmission oil was not changed regularly, the internal grease pressure would decrease after the amount of oil was reduced, and there would be phenomena such as starting failure and inability to refuel. 3. ** Engine related factors **: - When the engine had serious carbon pollution, the load on the first gear would increase, and the cylinder would have a slight fire phenomenon. This was not a problem with the transmission, but a cylinder of the engine had poor work, causing the angular speed of the output end of the crank to be different in a unit of time, causing the vehicle to stumble or rush. - The impact caused by the inertia of the internal operating components of the engine may also cause the CVS transmission to have a sense of stagnation, which is a normal phenomenon. 4. ** Other factors **: - The failure of the friction plate inside the transmission would cause a sense of frustration, so he needed to go to the 4S shop for maintenance. - Oil pump failure may also be one of the reasons. If the damage is not serious, you can apply soap on the damaged part, separate the damaged pump membrane from the intact pump membrane, stagger the damaged part, and then re-install it. If the damage is serious, you need to replace it. - The response speed of the transmission was not fast enough, and the speed of the upshift could not keep up with the speed of stepping on the accelerator. The moment the transmission changed gears, a sense of frustration would appear. This situation could be alleviated by stepping on the accelerator slowly. - The intervention of the energy recovery system would affect the engine speed, causing the engine speed to be out of sync with the clutch plate speed, resulting in a delay, which would require repair at the repair shop. - When driving at low speeds, if the gears were frequently switched between the first and second gears (such as low-speed crawling in a traffic jam), the clutch would constantly separate and combine, and the power transmission could not be completed smoothly in a short period of time, resulting in a low-speed setback. If there was a sense of hesitation when starting and at low speeds, it might be that the turbine was involved in the low speed and affected the engine speed. - If the oil was not sufficiently moistened, it would cause a setback, which could be solved by adding new oil.

The reason why the CVS suddenly accelerated and felt like it was slowing down might be the following: 1. ** Steel belt transmission characteristic **: CVs use steel belt friction transmission. When suddenly accelerating, the speed ratio of the driving wheel and the driven wheel will change rapidly. In order to prevent the steel belt from slipping, the oil cylinder will clamp the steel belt. However, during this process, the oil pressure of the electromagnetic valve was built with a sense of lag. When the steel belt slipped to the state of not slipping, there would be a change in speed, resulting in a sense of stagnation. This situation might be more obvious during sudden acceleration. 2. ** Engine power output problem **: - If the engine had serious carbon pollution, the cylinder might have a slight misfire when the load was suddenly increased. This was due to the poor work done by one of the engine's cylinders, causing the angular velocity of the output end of the crank shaft to be unequal in a unit of time, causing the vehicle to falter. This sense of falter was not entirely a problem with the CVS itself. - The inertia of the internal operating parts of the engine during sudden acceleration would cause a certain impact, which could lead to a sense of frustration. 3. ** Transmission oil problem **: When there is a problem with the oil, it may affect the internal transmission efficiency and oil pressure control of the CVS. It may cause a sense of frustration during sudden acceleration. 4. ** Gearbox response speed **: If the response speed of the CVS is not fast enough, the speed of the upshift cannot keep up with the speed of stepping on the accelerator when suddenly accelerating, and there will be a sense of hesitation at the moment of shifting. 5. ** Energy recovery system intervention (if there is)**: In some vehicles, once the driver suddenly speeds up and then releases the accelerator pedal, the generator in the energy recovery system will immediately start working, putting a burden on the engine, affecting the engine speed, causing the engine speed and clutch plate speed to be out of sync, resulting in a sense of frustration.

The reasons why the CVS transmission felt frustrated were as follows: 1. * * Steel belt related issues **: - The CTV transmission was driven by friction with a steel belt. When shifting gears, the driving wheel and the driven wheel had to increase their speed. When simulating shifting gears, in order to prevent the steel belt from slipping, the input shaft and the output shaft needed to have a speed ratio. When the speed ratio was abnormal (if it was too large, it was considered slipping), the oil cylinder began to clamp the steel belt. In the process of shifting gears, due to the lag of calculating the electromagnetic valve and the oil pressure, it was impossible to immediately enter the full transmission after the gear transmission, which would cause a short slip. From slipping to not slipping, there would be a change in speed, resulting in a slight rush, which was a sense of frustration. 2. * * Engine related problems **: - [Insufficient engine output power: When the engine has serious carbon pollution, the load will increase when the gear is raised, and the cylinder will have a slight fire.] This loss of fire was not a problem with the transmission, but a cylinder of the engine that did not work well, causing the angular speed of the output end of the crank to be different in a unit of time. This would cause the car to stumble or crash. - Engine speed fluctuation: Although the CVS transmission did not involve traditional gear shifting, when the accelerator was stepped on to refuel or the accelerator was released to decelerate, the fluctuation of the engine's torgue would also cause the vehicle to have a stumbling problem during driving. 3. * * Other factors **: - Transmission response speed: The reason for the pause in the upshift was mostly because the corresponding speed of the transmission was not fast enough. The speed of the upshift could not keep up with the speed of stepping on the accelerator, so there would be a sense of pause when the transmission shifted. - Energy recovery system intervention (on vehicles with energy recovery system): Most of the downshifts are due to the intervention of the energy recovery system. Once the driver releases the accelerator pedal or steps on the brake pedal, the generator will immediately start working, causing some burden on the engine, affecting the engine speed, causing the engine speed and clutch plate speed to be out of sync, resulting in a sense of frustration. - Gap beyond the standard range: Like the Audi CLV transmission, if the internal component gap exceeds the standard range, if the entire gap exceeds the range, there will be problems such as starting shake, stumble, impact, etc. - Transmission oil not changed regularly: Audi CLV transmission damage is also related to the transmission oil not being changed regularly, which may also indirectly lead to frustration.

If the CVS is unwilling to increase the speed when it steps on the accelerator, it may be caused by the following reasons: First, the oil pressure is insufficient, that is, the oil pump or oil pressure regulator of the CVS fails, resulting in insufficient oil pressure to push the steel belt to work; Second, the steel belt is worn out. Long-term use or improper maintenance may cause serious wear on the steel belt, making it unable to effectively transmit power; Third, the control unit fails. The control unit (TICU) of the CVS fails, and it cannot normally control the operation of the oil pump, oil pressure regulator and other components; Fourth, the sensors, such as the speed sensor and the oil temperature sensor, failed, causing the TICU to be unable to receive the correct signal normally, thus affecting the shifting strategy; Fifth, the driving habit problem. The driver stepped on the accelerator, causing the engine speed to reach the red line in a short time, but the actual speed did not increase. This situation would cause the shift delay of the CTV. It is recommended to go to a professional car repair shop for inspection and repair as soon as possible to ensure driving safety. The novel "Watching the Moon on Fish Island" is equally exciting.

For CVs, it was reasonable to say that stepping on and releasing the accelerator would speed up the car. When the vehicle's accelerator was released and stepped on again, the driving computer would determine that the owner wanted to overtake and increase the vehicle's power. The vehicle would downshift, increase the engine speed, and the engine's torque-burst would release more power. However, the CVS transmission was not made for intense driving. It pursued reliability, durability, and fuel rationality. Therefore, even if stepping on the accelerator would make the vehicle speed up relatively faster, the CVS transmission as a whole was not suitable for intense driving. Moreover, this operation may vary according to the specific conditions of the vehicle. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
There might be the following reasons why CVs couldn't accelerate when they stepped on the accelerator: 1. ** CVS steel belt slipping or wearing **: CVs rely on the steel belt to transmit power. If the steel belt is worn or loose, it will cause poor power transmission. Even if the accelerator is pressed to the bottom, it will be difficult to increase the speed. 2. ** Throttle Failure **: The throttle controls the air intake of the engine. Dirty or faulty air intake will affect the engine's power output, thus limiting the speed of the vehicle. 3. ** Sensing Failure **: The engine sensor monitors the working state. When it fails, it will send an error signal to the engine control unit, affecting the normal operation of the engine and causing the speed to be unable to increase. 4. ** fuel system problem **: Failure of the fuel pump, fuel injection, and other fuel system components will cause insufficient fuel supply or unstable fuel pressure, affecting the engine power and making it impossible to speed up. 5. ** Cold state or cold protection **: When the car is cold, the oil temperature of the transmission is low, and the grease is insufficient. If you step on the accelerator too hard, it will cause too much instantaneous moment, which will easily cause abnormal wear and tear to the output shaft and steel belt of the transmission. The driving computer may limit the gear up of the transmission, resulting in limited speed. 6. ** Coke deposit problem **: Long-term driving at low speed and high gear will easily cause coke to deposit on the engine, affecting work efficiency, slowing down the accelerator response, and limiting the speed increase. 7. ** Speed sensor malfunction **: This sensor is used to detect the speed of the vehicle. When the speed sensor fails, there will be a sense of hesitation when changing gears, which may also affect the speed increase. 8. ** Electromagnetic valve damaged **: The electromagnetic valve controls the fuel injection and valve opening. Damage will cause uneven fuel injection, affecting the engine operation. It may cause problems such as over-heating, impact, and slipping of the transmission, which will affect the speed of the vehicle. The novel " Watching the Moon on Fish Island " is equally exciting.
