• What is the reason for the loud start-up sound of the new car
• 4, Why is the car so loud when it starts

What is the reason for the abnormal sound when the car starts?

The engine claw pad is aging. The claw pad plays the role of supporting the engine. After aging, it will make a strange sound when the car starts.

There are many reasons for abnormal noise when the car starts, including low engine temperature, thermal expansion of car ternary catalyst, gearbox failure, engine belt or chain wear, etc. The engine temperature is too low: When the car is cold started, the engine temperature is too low to work normally. At this time, it is normal to have some abnormal noise.

Once the fuel of the car is insufficient, there will be a rattling sound when the engine is started, but it will also occur if it cannot start normally.It is necessary to check whether the fuel is sufficient. This problem is very easy to solve. You only need to add fuel in time.

The reasons for the abnormal sound of the car start and the solution are as follows: there is a sharp sound when the car starts.

The specific reasons for the abnormal noise of the vehicle when starting or driving are as follows: the abnormal noise of the engine. The abnormal noise in the engine compartment is usually the abnormal sound of metal harsh. The abnormal noise of the engine is mainly caused by excessive wear or improper assembly and adjustment of some parts.

What is the reason for the abnormal noise of the engine

1. The abnormal noise of the car engine may be caused by the high temperature caused by high engine load intensity, or low engine oil pressure.Causes of abnormal noise in the car engine: engine overheating, engine carbon accumulation, poor oil, need to add high-grade oil; overheating of the engine, check the cooling system; blockage of the exhaust system.

2. The loud engine noise may be due to the following reasons. The rubber block laid between the engine and the frame - the foot glue is aging or loose. Its function is to reduce the vibration and buffering of the engine when it is working, and to give full play to the effect of fixing the engine. When these rubbers age or relax, they will produce engine vibration, and the faster the speed, the louder the vibration sound.

3. Oil: If the viscosity of the vehicle's oil is too high, it is easy to cause problems with engine operation, and the lubrication effect will become worse, resulting in loud engine noise. Therefore, at this time, you should go to the repair shop in time to check whether it is time to change the oil, or calculate by yourself whether the maintenance time has come.

4. The abnormal noise and jitter of the engine generally have the following reasons: 1. The foot glue is aging or loose; the engine cylinder is abnormally missing; the cylinder is abnormal; the mixture is too thick; the timing gear noise is abnormal. The foot glue is aging or loose; the foot glue is a rubber block between the engine and the frame.

5. Only by figuring out the real reason for the loud engine noise can we "pressure the right medicine" to avoid the waste of engine oil and the increase in vehicle maintenance costs caused by blindly replacing the oil.

What is the reason for the loud start-up sound of the new car

1. As for others, it may be internal problems of the engine, such as EGR valve blockage. 3. The engine has a hissing sound, just like steam or air coming out of the engine. Generally, after hearing this sound, the engine will quickly lose power.There may be a problem. The engine is overheated. Check the cooling system.

2. Caused by engine carbon accumulation, because the old engine oil is getting thinner and thinner, more and more carbon accumulates. When the oil is thin, it is easy to spee the oil, resulting in more and more carbon accumulation and loss of a lot of power. When replacing with new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, resulting in loud engine noise.

3. The main reasons for the loud sound are as follows: 1. When the cold car starts the vehicle, the temperature of the internal parts is very low. Because the vehicle is parked for a long time, the oil in the engine flows back into the oil pan shell, so the starting sound of the vehicle will be greatly increased. When the cold car starts, the speed is much higher than normal, so the accompanying noise will be greater.

4. What's wrong with the loud noise of the car just starting the engine? 1 The engine foot mat is aging, resulting in the inability to reduce the vibration.The engine and the frame are softly connected, and the machine foot mat is separated from the engine and the frame. Over time, the rubber rubber cover of the machine foot mat slowly ages and loses its original. Shock-absorbing effect, the noise will naturally become louder.

5. The car is loud when it first starts, and the first reason is the high speed. When the car is cold started, the speed will be higher, which can make the engine quickly enter the best working state, and then let the ternary catalyst enter the best working state as soon as possible. Lubrication protection is not in place.

6. The tire is too noisy. The tire noise of models that usually use explosion-proof tires will be relatively loud, which can be improved by replacing silent tires. The noise of the vehicle will become louder during cold start. In the case of low-temperature cold start, the vehicle idle speed will be higher and the jitter will increase, but as long as the temperature of the vehicle rises, the noise will be significantly reduced.

Why is the car loud when it first starts

Try to check the coolant, the oil pressure is too high or too low, check the oil pressure gauge, and there may be a problem with the ignition time setting, which will also lead to such symptoms. As for others, it may be an internal problem with the engine, such as EGR valve blockage.

It is caused by engine carbon accumulation. Because the old engine oil is getting thinner and thinner, it accumulates more and more carbon. When the oil is thin, it is easy to spee the oil, resulting in more and more carbon accumulation and loss of a lot of power. When replacing with new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, resulting in loud engine noise.

The engine foot pad is aging, resulting in the inability to reduce the vibration. Engine and frameIt is softly connected, and the engine and the frame are separated by the foot mat. Over time, the rubber rubber cover of the foot mat slowly ages and loses its original shock absorption effect, and the noise will naturally become louder. The design of the vehicle itself leads to loud noise.

The main reasons for the loud sound are as follows: 1. When the cold car starts the vehicle, the temperature of the internal parts is very low. Because the vehicle is parked for a long time, the oil in the engine flows back into the oil pan shell, so the starting sound of the vehicle will be greatly increased. When the cold car starts, the speed is much higher than normal, so the accompanying noise will be greater.

This is normal. It takes a process to establish the oil pressure of the cold car to start the engine. The lubrication effect is poor, so the noise is large. 2 In addition, after the cold car starts, in order to reach the normal operating temperature as soon as possible, the idle speed will be high, and the noise will be loud. If the noise slowly decreases with the idling speed decreases until it disappears.It's all normal.
