the buzzing sound of the acceleration engine

[Pacific Automobile Network] The reason for the buzzing when the engine accelerates is: abnormal sound of the gearbox; abnormal sound of the valve; abnormal sound of the engine. Car acceleration is the most test of the quality of the car. Many car problems will appear when the car accelerates. Pay attention to maintenance at ordinary times.

The buzzing sound produced when the gearbox is accelerated is not always made by the engine. It is also possible that the gearbox bearing wear and lubricant are reduced, resulting in friction. If the engine problem is indeed the buzzing sound of the engine, it depends on whether the speed is very high. If the speed increases during acceleration and The speed increase is very slow.

** Exhaust system problems: ** Poor connection of the exhaust pipe, leakage of the exhaust pipe or other exhaust system problems may cause sound. Check all parts of the exhaust system to ensure that they are intact. **Engine problems:** Engine problems, such as damage to the belt or roller, may make a buzzing sound when accelerating.

The reason why the car acceleration engine buzzes is: the engine lacks a cylinder or knocks the cylinder. The oil is dirty or there is a problem with the quality. The connecting rod bearing and the crankshaft bearing are loose, the shaft tile is melted or the size does not match and rotates. The bearing wear of the engine belt link part.

The sound of the engine is loud as soon as it accelerates

Clean the throttle valve. As soon as the engine speeds up, the noise is particularly loud. If it is caused by dirty throttle valves, the noise can be improved by cleaning the throttle valve. Repair or replace spark plugs and ignition coils.

There is also the problem of internal valve blockage and so on. If there is a loud noise when accelerating or decelerating, then look at the generator shaft, even the water pump, power steering pump, etc.There is a sound similar to "spout" in the engine, and it is recommended to change the oil.

The exhaust system is faulty. The phenomenon is that the engine has a hissing sound, just like steam or air coming out of the engine. For example, when the intake and exhaust pipe leaks, as soon as the vehicle accelerates, the exhaust rate accelerates, and the vehicle will have a loud roar. The engine is out of order. There are more reasons for this.

The reason for the loud noise when the engine accelerates is the leakage of the exhaust pipe, the dirty blockage of the throttle valve, the lack of the engine cylinder, the problem of the gearbox, etc. Exhaust pipe leakage: When the intake and exhaust pipe leaks, as soon as the vehicle accelerates, the exhaust speed will accelerate, and then the vehicle will make a loud roar.

Exhaust pipe leakage: When the intake and exhaust pipe leaks, the vehicle accelerates and the exhaust rate accelerates, and the vehicle will make a loud roar at this time.

What is the reason for the loud roar of high-speed engines?

When driving at high speed, the engine sound becomes louder for the following reasons: use inferior oil: most new cars are injected with fully synthetic oil for the first time, and abrasives are also added, so the viscosity is low and the quality is good.

The main reason for high-speed engine noise: This situation is mainly caused by the decline in oil quality, low oil pressure, poor lubrication, and loud engine noise.

The loud noise of the high-speed engine may be due to the high viscosity of the vehicle oil, resulting in problems in engine operation, poor lubrication, resulting in loud engine noise. Therefore, you should go to the repair shop in time to check whether it is time to change the oil, or calculate whether the maintenance time has arrived.

The accelerator is buzzes when you step on it slightly larger

There is a buzzing sound when the car's refueling door. What is the reason for the buzzing of the car when stepping on the accelerator? The reason for the buzzing of the vehicle's refueling door is: excessive carbon accumulation in the engine, poor gasoline filtration, gasoline quality problems, fire Flower plug aging, engine failure, cylinder failure.

What is the reason why the car buzzes when you step on the accelerator: Oil problem: If the owner's car lacks oil or the oil is of poor quality, the owner will hear a buzzing every time he starts the car. Engine cylinder deficiency: mainly refers to the fact that several cylinders or one cylinder may not work properly during the operation of the engine.

This may be caused by damage to the engine foot mat. After this situation, it is recommended to check the foot mat of the engine. If the foot mat is damaged, it can be replaced directly.The foot pad is at the junction of the engine and the frame. The function of the foot pad is to cushion vibration and jitter. This part can improve the comfort of the car.

This may be caused by damage to the engine foot mat. After this happens, it is recommended to check the engine foot mats. If the foot mat is damaged, it can be replaced directly. The foot pad is at the junction of the engine and the frame. The function of the foot mat is to buffer vibration and jitter, which can improve the comfort of the car. The machine mat is a rubber product, which will age and harden if used for a long time.

The speed-up engine of the car roars loudly, and sometimes the speed can't be raised. What is the reason?

Second, the transmission of the vehicle slips and wears out, and the power output by the engine cannot be transmitted to the tires of the vehicle.These two factors cause the vehicle to step on the accelerator, the engine speed is buzzing, but the speed of the vehicle cannot be increased. There are many reasons for insufficient engine torque. The following are a few details: lack of engine cylinder: which is what we often call the phenomenon of fire failure.

Sometimes because the car is driving at high speed and the load is too large, our engine needs a strong point firepower, but the resistance of the high-voltage line is too large, resulting in the point firepower not being able to meet the demand, resulting in the inability to increase the speed of our car. At this time, we should replace the high-voltage line in time.

Is the ternary catalysis blocked? According to the description of the questioner, the speed is weak and stuffy, and the sound is louder than usual, which is very similar to the fault phenomenon of ternary catalytic blockage, because the ternary catalytic blockage will cause the engine exhaust to be difficult, so that the increase in engine speed is far behind the depth of the accelerator pedal, which makes people feel stuffy and weak.

With several common situations: The reason for the loud noise when the engine accelerates is the leakage of the exhaust pipe, the throttle valve is dirty and blocked, the engine cylinder is missing, the gearbox problem, etc. Exhaust pipe leakage: When the intake and exhaust pipe leaks, as soon as the vehicle accelerates, the exhaust speed will accelerate, and then the vehicle will make a loud roar.
