What's wrong with the sound of the engine

The mixture is too thick: When the engine is too thick, the phenomenon is: it is difficult to accelerate after starting, and the engine runs unevenly; There is black smoke from the trachea, and the engine is accompanied by a strange rattling sound; the engine power decreases and the fuel consumption increases. Most of these are related to carbon accumulation, filter blockage, etc., and generally do not need to be overhauled.

The sound of the engine may be caused by the following reasons: the abnormal sound of the engine belt, such as the generator belt, the air conditioner belt, the steering booster pump belt, etc. It may be that the belt is too loose or too tight, or the belt may be aging. Adjust the elasticity of the belt, apply butter to the belt, or replace The belt can solve it.

After the car is turned off, there is a crackling sound near the engine, which is a normal phenomenon caused by the thermal expansion, cooling and contraction of the exhaust pipe and the heat insulation pad.

The sound of car engine "da da da" is usually the sound of the valve or fuel injector. The carbon tank solenoid valve also has this sound, but it is relatively crisp. Give some oil when idling to see if the frequency has changed. If the frequency remains unchanged, it is the sound of the solenoid valve; if the frequency changes, there should be an abnormal sound at the valve.

In fact, this "click" abnormal noise is caused by the fact that the oil pressure is not fully established when the oil pump is cold started, resulting in the lubrication failure of various parts. Under normal circumstances, after the engine runs for a period of time, the clicking noise will disappear. Abnormal stattling: 1.

Is it normal for the car engine to have a "da-da-da" sound?

The sound of the car engine is usually the sound of the valve or fuel injector. The carbon tank solenoid valve also has this sound, but it is relatively crisp. Give some oil when idling to see if the frequency has changed. If the frequency remains unchanged, it is the sound of the solenoid valve; if the frequency changes, there should be an abnormal sound at the valve.

There is a strange sound when the cold car is on fire, and there is no sound after the hot car. It is generally caused by the fact that the oil pump has not fully established the oil pressure when the cold start, and the parts are not lubricated. It is a normal phenomenon.

Car engines make a clicking sound, which is a normal phenomenon.When the vehicle is first started, because the temperature of the internal pipe of the body is too low, there may be a rattling sound when the oil is circulating.

This sound may be normal or abnormal, and it needs to be checked to determine whether it is normal. So, under normal circumstances, which parts of the engine will make a "da-da-da" sound? Let's say it briefly.

This is the sound of the valve sound. The valve sound is caused by the excessive valve gap. The excessive valve gap is caused by wear between the camshaft and the valve column. The valve of the car engine with a long mileage will have some abnormal noise, which is a normal phenomenon. If you want to solve this problem, you can replace the new camshaft and valve column.

What's the matter with the rattling sound of the car engine?

commane disease. The car is not in a cold state. When the water temperature reaches the normal temperature, the engine will make a clicking sound, which can be heard clearly in the cab. This phenomenon is found in many models, including Japanese, German, Korean, French, etc.

There is a rattling sound in the engine, which may be caused by the following reasons: abnormal noise from the engine belt, such asMotor belts, air conditioning belts, steering booster pump belts, etc., may be that the belt is too loose or too tight, or the belt may be aging. Adjust the elasticity of the belt, apply butter to the belt, or replace the belt.

The sound of car engine "da da da" is usually the sound of the valve or fuel injector. The carbon tank solenoid valve also has this sound, but it is relatively crisp. Give some oil when idling to see if the frequency has changed. If the frequency remains unchanged, it is the sound of the solenoid valve; if the frequency changes, there should be an abnormal sound at the valve.

The possible reasons for the rattling sound of the engine are as follows: it may be the sound of the valve of the engine, because the excessive wear of the valve parts causes the abnormal sound of the engine. Maybe the pressure of the oil pump is insufficient. It may be the problem of oil viscosity. The oil will become more sticky in winter and not easy to flow, resulting in abnormal engine noise.

What is the reason for the sound of the engine?

There is a clicking sound in the engine, which may be caused by the following reasons: abnormal noise of the engine belt, such as generator belt, air conditioning belt, steering booster pump belt, etc. It may be that the belt is too loose or too tight, or it may be that the belt is aging. Adjust the elasticity of the belt, apply butter to the belt, or more It can be solved by changing the belt.

The possible reasons for the rattling sound of the engine are as follows: it may be the sound of the valve of the engine, because the excessive wear of the valve parts causes the abnormal sound of the engine. Maybe the pressure of the oil pump is insufficient. It may be the problem of oil viscosity. The oil will become more sticky in winter and not easy to flow, resulting in abnormal engine noise.

The following are some possible sounds and their corresponding reasons: the crackling noise when the cold car starts may be caused by the oil not circulating into lubrication, and the sound will be reduced after the normal oil cycle.

The engine exploded. It is a sound similar to metal knocking, which can also be called a knocking cylinder. There are three reasons for the failure: A. The fuel is not qualified, and the use of inferior fuel or low-standard fuel. B. Engine timing control errors, such as the ignition advance angle is too large, etc., readjust the timing.

What are the reasons why the sound of the car engine becomes louder?

1. The wrong number of gasoline is added, or the gasoline is not qualified. If the car needs No. 97 gasoline, but No. 93 gasoline is added, so, noIt will only reduce the life of the engine, more likely to produce carbon accumulation, and also make the exhaust gas black. At this time, the sound of the car engine makes people feel that it is obviously louder.

2. The engine accumulates too much carbon. The engine oil is used inappropriately or the oil becomes dirty. In addition, most of the engine noise is caused by the abnormal noise of the engine: the screws under the engine are loose. A relatively common minor fault, tightening or adjusting the under-engine guard screw. The engine claw pad is aging.

3. The gasoline with the wrong number, or the gasoline is not qualified. If the car needs No. 97 gasoline, but add No. 93 gasoline, it will not only shorten the life of the engine, but also make it easier for the exhaust gas to turn black. At this time, the sound of the car engine is obviously louder. Nozzle atomization will also cause abnormal engine noise. Shock absorber failure.

4. The reasons why the engine sound becomes louder are: the oil is low or the oil is not hot when the car is cold, and the oil pressure is insufficient. There are too many impurities or dirt in the oil, which makes it impossible to effectively adjust the oil pressure. The engine has mechanical interference and the lubricating oil road is blocked.

What is the reason for the clicking sound of the engine?

1. There is a rattling sound in the engine, which may be caused by the following reasons: abnormal noise of the engine belt, such as the generator belt, air conditioning belt, steering booster pump belt, etc. It may be that the belt is too loose or too tight, or it may be that the belt is aging. Adjust the elasticity of the belt and apply butter to the belt, or It can be solved by replacing the belt.

2. The engine has aThe possible causes of the sound are as follows: it may be the sound of the valve of the engine, because the valve parts are excessively worn, resulting in the abnormal sound of the engine. Maybe the pressure of the oil pump is insufficient. It may be the problem of oil viscosity. The oil will become more sticky in winter and not easy to flow, resulting in abnormal engine noise.

3. The following are some possible sounds and their corresponding reasons: the crackling noise when the cold car starts may be caused by the oil not circulating into lubrication, and the sound will decrease after the normal oil circulation.

4. A common disease. The car is not in a cold state. When the water temperature reaches the normal temperature, the engine will make a clicking sound, which can be heard clearly in the cab. This phenomenon is found in many models, including Japanese, German, Korean, French, etc.

5. It is a sound similar to metal knocking, which can also be called a knocking cylinder.There are three reasons for the failure: A. The fuel is not qualified, and the use of inferior fuel or low-standard fuel. B. Engine timing control errors, such as the ignition advance angle is too large, etc., readjust the timing.

6. One reason is that the viscosity of the oil you use is not enough, resulting in poor lubrication effect. Generally, it is recommended that you use 40 oil. If you are satisfied, please adopt it.
