There is no abnormal sound when the car is refueled on the spot, and there is a whining sound when r

If you do this, it may be a problem with the three-way catalytic converter, or there is a leak in the exhaust pipe, so it is best to go to a professional shop to repair it.

Hello, it is recommended to go to the pit station to raise the car and check the exhaust pipe to see if there is any damage caused by air leakage.

In this case, you should go to the maintenance plant to clean the three-way catalytic nozzle, fuel injector, and replace the spark plug to ensure that the oil supply is sufficient to improve the power.

In this case, you can consider the problem of the three-way catalytic converter, or the exhaust pipe is leaking, and you can check it specifically.

In this case, it may be a problem with three-way catalysis, you can go to the dealership repair shop to check it and find a master to repair it.

Hello, it may be a problem with the three-way catalytic converter, or there is a leak in the exhaust pipe, go to the 4S store to test it

In this case, you can check the three-way catalysis, the problem, or whether there is any air leakage in the exhaust pipe? The underworld star store is more professional, and there are four S stores to check it.

You seem to need to check this situation with the repair shop, it is likely that the wheel bearing is damaged and needs to be overhauled first.

This situation is generally caused by three-way catalysis, so check it first to see if there is any air leakage.

Hello, in this case, you should go to the nearest professional maintenance point and find professional maintenance personnel for maintenance. Focus on the exhaust cylinder and three-way catalysis.

Hello, how long has this car been driving, is there a leak in the exhaust cylinder, or is it a problem with the three-way catalytic converter.

It is possible that the tire bearing is broken.

Hello, it may be that the accelerator pedal sensor is broken, resulting in the failure to detect the accelerator signal.

When the vehicle starts cold, the oil is not fully lubricated in the various parts, the sound will generally be louder, and so the idle speed will be lowered, the sound will be smaller, if the car is hot for a while, there is a sound, consider whether there is a reason for the aging of the belt parts, including whether the engine is used for too long and other reasons, open the hood, find the sound**, and troubleshoot in time, so that the engine can achieve the best working condition.

Answer: After the car starts, the engine roars without stepping on the accelerator, like the sound of continuous refueling, the reason is (1) this is the engine is cold and the car is idling, which is a normal phenomenon; (2) The engine electronic control module automatically controls the engine idle speed through the idle motor or electronic throttle valve; (3) The engine is cold and fast idling, the engine running parts are poor lubrication due to the high viscosity of the oil, the slow oil coming up, and the engine speed is fast, so the engine will have a roaring sound, like the sound of continuous refueling.

Summary. 1. It's not the engine's problem, but the two nuts of the front drive shaft are loose, just go to the repair department to tighten it. 2. The accelerator, the device for controlling the fuel supply on the internal combustion engine, and the accelerator of the automobile engine are generally controlled by the pedal, also known as the accelerator pedal, which is the device for controlling the fuel supply of the automobile engine.

3. The accelerator pedal is also known as the accelerator pedal. It is part of the automobile fuel supply system. By controlling the amount of pedaling, the engine throttle opening is controlled, the air intake is controlled, and the computer controls the oil volume, so as to control the speed of the engine.

4. Hidden danger treatment: In case of driving a new car, you encounter a problem with the accelerator pedal. Don't panic, according to the advice of professionals, press the brake pedal with all your might, stop the car and turn off the engine, and then contact for rescue.

If the accelerator pedal is pressed three-quarters of the way down and the engine still can't increase the speed accordingly, you should shift to a lower gear and then press the accelerator pedal to accelerate. Before the car stops and turns off, the accelerator pedal should be released first, and the accelerator pedal should not be blown out violently. General Essentials:

Gently step on and lift slowly, accelerate in a straight line, use soft force, should not be too hasty, toe kung fu, do not tremble.

The correct way to step on the accelerator:

When the car is going uphill, do not step on the accelerator pedal, and when using a low gear, the accelerator pedal should generally be stepped down halfway. When the car is rambling, do not press the accelerator pedal all the way. If the accelerator pedal is pressed three-quarters of the way down and the engine still can't increase the speed accordingly, you should shift to a lower gear and then press the accelerator pedal to accelerate.

Before the car stops and turns off, the accelerator pedal should be released first, and the accelerator pedal should not be blown out violently. General essentials: lightly step on the slow lift, accelerate in a straight line, use soft force, should not be too hasty, toe kung fu, do not tremble.

Is there a gearbox?

This is mainly to check that your belt is not loose, to check whether your belt tensioner is worn, and to check whether your other bearings are worn.

It is normal for the engine to hum when it is on the gas pedal. This is because the engine is increasing the power output, and the gasoline in the engine cylinder is burning to produce a dynamic and wide force, and the larger the throttle, the louder the engine sound will be, and the louder the exhaust sound will be, which is no problem. It's just that the big throttle consumes more fuel.

An engine is a machine that converts other forms of energy into mechanical energy, and a gasoline engine is a power unit that converts chemical energy into mechanical energy. The cooling system of the engine ensures that the engine works at the most suitable temperature by absorbing the heat of the parts, the cooling system can be divided into air cooling and water cooling according to the different cooling mediums, air cooling is to dissipate the heat of the parts in the engine directly into the atmosphere for cold cooling, water cooling is to transfer the heat to the cooling water, and then dissipate it into the atmosphere, the cooling effect of the water-cooled engine is better, and most of the engines are currently using the water cooler cooling system.

When the vehicle starts cold, the oil is not fully lubricated in the various parts, the sound will generally be louder, and so the idle speed will be lowered, the sound will be smaller, if the car is hot for a while, there is a sound, consider whether there is a reason for the aging of the belt parts, including whether the engine is used for too long and other reasons, open the hood, find the sound**, and troubleshoot in time, so that the engine can achieve the best working condition.

If it can stay smoothly at more than 1000 rpm, and can automatically lower after lasting tens of seconds, it is not a fault, because now the vehicle is designed, in order to make the engine preheat as soon as possible, reduce the cold car wear and tear of the engine, the specially designed cold car high idle speed, and so on The water temperature has been increased, that is, the normal idle speed can be restored. If there is a significant change in the idle speed, it can be called a traveling car, that is, the idle speed is unstable, this situation is generally caused by the dirty throttle, only need to clean the throttle, and do a good job of matching the problem is solved.

Abstract 1, the oil is not fully lubricated to the engine parts, when the operation for a period of time, the new oil can be evenly lubricated to the engine parts.

2. If it is not good after a period of time, it may also be that the wear is more serious, and then the inside of the engine is also cleaned to make the wear gap larger.

3. If the gap is large and the seal is not good, the condition of the engine will also deteriorate, and there may be noise, so it is recommended to go to the repair shop for inspection.

4. If you don't pay attention to maintenance, it may be caused by too much carbon deposition in the machine (too much carbon deposition in the engine, too much carbon deposition in the throttle, too much carbon deposition in the spark plug, etc.), go to the repair shop to clean it.

5. It may also be caused by poor filtration (the most common is that the air filter is too dirty) to go to the repair shop to clean or replace.

2. Check whether the air conditioning pipeline is immediately on the body. If the air conditioning pipe is immediately attached to the car body, it will affect the resonance and will also cause a whining sound. 3. Detect the booster oil pot to see if there is any aging of the booster oil and lack of booster oil.

Solution: Replace or add booster oil. 4. Check whether the bearing is damaged.

Key inspection of generator bearings and booster pump bearings. If it is damaged, replace it immediately.

Thank you!! Have a great day!

The repair shop said it was faulty with the booster pump.

Said to change the pump. I haven't decided yet.

You can find a few more to see.

1) Due to the fact that the car is not heated before driving, it is generally possible to start after a minute of heating up the car before driving, and the hall is particularly cold when the weather is cold.

2) It is also possible that the exhaust pipe is slightly deformed and leaking, or check whether there is any air leakage in the air intake system, and whether there is any abnormal noise caused by the engine belt assembly.

3) It may also be the sound of the half shaft, bearing, etc.

Note: If you are not at ease, it is recommended that you go to the 4S store to check the following, so that the problem can be solved directly.

If the car squeaks when you press the accelerator, it may have a lot to do with the belt or the oil pump, so it is recommended that you check the belt first. Often, if the oil pump fails, the fuel supply will be insufficient or the vehicle will not start.
