What is the reason for the loud noise of the Zhixuan engine

The reason for the loud noise of the Zhixuan engine: If the engine is active for a long time, so that the surface overheats, the cooling system will strike . At this time, the first thing to do is to check the cooling system. If there is a problem with the cooling system, it may lead to blockage of the exhaust, because the vacuum tube is likely to break.

Low oil pressure or wear of the hydraulic column itself.Due to the low oil pressure or the wear of the hydraulic column itself, the Toyota Zhixuan causes the hydraulic column to enter the air and produce abnormal noise. Zhixuan is the official statement of GAC Toyota that a new model will be released to the market every year in the future, including a new small car with a higher positioning than YARiS L Zhixuan, a new small SUV.

There is a lot of noise in the engine due to carbon accumulation. The oil label is not suitable for use. The foot glue is old or loose. The engine lacks a cylinder. Low-temperature cold start, etc. First of all, check the engine oil rif to see if the oil level is low. If it is low, refuel it to return it to its original position. What if the engine is still noisy? Check your oil pressure.

The reason for the snoring sound of Zhixuan 1200 is the insufficient tensioning force of the tensioning wheel, resulting in the slippage of the belt.

The strange sound of dadada, there areThe reason for the valve is normal. If the co-driver's place is noisy, it may be that the oil pipe is loose, or there is a gap in the place where the oil pipe is released. The solution is to plug the filler. It is also possible that the problem of carbon accumulation causes abnormal noise, and the solution is to clean up the carbon accumulation.

What is the reason for the lack of strength of the car when listening to the sudden sound behind the start of the Toyota Zhixuan car

1. Analysis of the problem: This problem is usually caused by insufficient rigidity of the body, resulting in the deformation of the vehicle during driving, the friction or shaking of the door and the frame, or some ground The friction between the steel plates is caused by de-soldering.

2. As mentioned above, the biggest possibility is that the throttle valve is too dirty, and there is too much carbon accumulation in the fuel nozzle and intake channel. In the cold case, the carbon accumulation will adsorb part of the fuel, and if the fuel does not completely enter the cylinder to burn, it will produce the symptoms of idling instability and difficulty in starting.

3. The abnormal sound of the chassis of Toyota Zhixuan 18 is neither the balance bar rubber sleeve nor the hem arm. The ball head of the car chassis is rusted orIt is the wear that causes the car chassis to rattle. At this time, it is necessary to replace the new car chassis ball head, and it can also be lubricated.

4. The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston pin assembly or the connecting rod bearing assembly is too tight; the gap between the rod and its guide hole is too large; the contour of the gas distribution cam is worn; sometimes, the starting grip is loose and the pulley makes the pulley sound (obvious when the speed changes).

5. Analysis of the cause of car shaking: cold start shaking First of all, starting from the cold start, the main reason for cold start body shaking is insufficient fuel combustion, resulting in insufficient power of the car. The ignition energy is low. When starting, especially when the temperature of fuel and lubricating oil is low, more oil is needed to meet the power.

6. It may be a valve or a connecting rodIf the crankshaft tile gap is too large, you need to disassemble the engine to check whether the internal parts cooperate with the gap caused by excessive abnormal noise. I am very happy to answer your questions and hope to help you. I wish you a happy car! [ For car questions, ask the car master. 4S store professional technician, 10 minutes to solve.

Toyota Zhixuan has a loud sound. Can the sound be quieter after installing the tail throat?

1. Toyota Zhixuan is a compact car with a certain noise and vibration in its engine. Installing a tail throat can improve the exhaust sound and performance of the car, but whether it can reduce the overall noise of the vehicle depends on the specific situation.

2. Working sound of carbon tank solenoid valve: This is a normal sound and can continue to be used. If the sound is too loud, it is recommended to go to the 4S store for inspection.

3. Toyota Zhixuan x new 2022 is loud, because the sound insulation effect of Toyota Zhixuan x new 2022 is poor, so it sounds like Toyota Zhixuan x new 2022 is loud.

4. The reason for the loud noise of the dazzling engine: If the engine is active for a long time, so that the surface overheats, the cooling system will strike. At this time, the first thing to do is to check the cooling system. If there is a problem with the cooling system, it may lead to blockage of the exhaust, because the vacuum tube is likely to break.

5. The exhaust pipe behind and the ternary catalyst make a sound in the cold. In this case, the trunk lock is generally not well adjusted or the spare tire frame is not tightened, and the accompanying tools and fire extinguishers. If there is no problem, it may be a fault of the trunk site, such as the wear of the rubber sleeve, etc.

How to turn the noise of the Toyota Zhixuan engine too loud?

1. In addition to replacing the tail throat, you can also consider other noise reduction methods, such as switching to low-noise tires, replacing engine brackets, replacing door seals, soundproof gauze, etc., and make choices according to the actual situation. In a word, when carrying out any vehicle modification or maintenance, please be sure to follow the relevant standards and regulations to ensure safety and correctness.

2. The rear box is very easy to produce resonance noise. The treatment method is barley damping board and sound-absorbing cotton.

3. When accelerating, the engine makes a howling sound, or when it slows down, it also appears. In short, it changes with the RPM, and the volume of the sound changes.The possible reason is that the power steering oil is missing, fill it up. The generator bearing may be damaged. Problems with power steering pumps and water pumps will produce similar noises.

4. The probability of damage of the exhaust gas circulation valve and exhaust pipe mileage is very small. Excessive use of fuel and cleaning products has caused damage to car engines.

5. The abnormal sound of the da-da is caused by the valve, which is normal. If the co-driver's place is noisy, it is possible that the oil pipe is loose, or there is a gap in the place where the oil pipe is released. The solution is to plug the filler. It is also possible that the problem of carbon accumulation causes abnormal noise, and the solution is to clean up the carbon accumulation.
