Why does the car chassis always have a strange sound?

1. The reasons for the abnormal noise of the automobile chassis are: the abnormal noise caused by the looseness and deformation of the chassis parts; the abnormal noise at the tire noise level of the tire; the abnormal noise of the chassis parts such as the automobile engine or transmission;Abnormal noise of each transmission device; abnormal noise of front and rear wheel bearings; abnormal noise of various important safety parts, etc.

2. Most of the abnormal noise of the exhaust pipe is basically caused by the rupture or leakage of the exhaust pipe. After the vehicle starts, there will be a "poof" noise.

3. The reason for the abnormal noise of the car chassis: The abnormal noise made when the vehicle starts is generally due to the failure of the suspension system, which may be caused by loose or damage to the engine bracket. The abnormal sound made when the vehicle turns may be due to the failure of the steering system and the suspension system.

Why does the car always shake at idle speed?

1. Causes of car idling jitter: serious carbon accumulation, ignition system problems, unstable oil pressure, aging engine parts.

2. The main reason for idling jitter;The most common cause of car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

3. The causes of car idling jitter include spark plug failure, excessive carbon accumulation, and oil supply system failure. Spark plug failure: The spark plug is a wearable part. If too much carbon or too large ignition gap is found, it needs to be replaced. Excessive carbon accumulation: The idling jitter of the car in use is caused by carbon accumulation. When the engine is running, carbon will be generated on the throttle valve and fuel injector.

4, "Related introduction: The reason for the shaking of the car's idling engine: the throttle valve is too dirty, and the engine of the car is in an idle state after starting. At this time, the air needs to constantly pass from the throttle valve to the cylinder and burn gasoline.

What is the impact of the car always mixed with gasoline?

1. If it is often mixed, it will affect the engine without better support, or excessive support will affect the performance of the engine, which may cause problems with the engine in the long run. However, it is not a big problem to add a mistake occasionally. Relatively speaking, as long as it is not diesel, it will not have much impact.

2. If gasoline is mixed for a long time, it will cause the engine to not work for a long time.In the best state, the explosion resistance of gasoline is high for a while and low for a while. The engine does not work normally at all, and it will often explode, which will also lead to a weakening of power.

3. [Pacific Automobile Network] If it is often mixed, it will have an impact. After all, if the engine is not better supported, or excessive support, it will affect the performance of the engine, which may cause problems with the engine in the long run.

4. Because the gasoline additives and chemical composition of different labels are different, the mixed use of gasoline of different labels is definitely harmful to the car. If the owner frequently mixes oil products for a long time, the harm to the car is not a little bit.

What is the quality and total mass of a car, and what is the difference between them?

1. The quality of the car refers to the weight after the car is fully equipped according to the factory technical conditions (such as spare tires, tools, etc.), and all kinds of oil and water are added. The total mass of the car (G) refers to the weight of the car when it is fully equipped and filled with passengers (including drivers) and goods according to regulations.

2. The difference is that the quality of the preparation is the quality of the empty car when it is ready to drive under normal conditions and has not yet carried people (including drivers) and goods. The total mass is the weight when filling the passenger (including the driver) and the goods.

3. The total mass of the vehicle refers to the weight of a car when it is fully equipped and filled with passengers and goods according to regulations, and the quality of the equipment is the self-weight of a car that people often call.

4. The difference between the quality of preparation and the total mass is: different meanings and scopes.

5. The quality of the vehicle is the weight of various liquid containers on the vehicle after being filled according to the standard, and the total mass is the mass of the preparation plus the weight of the driver and passenger plus the weight of the item.

6. The quality of the car, that is, the "empty car weight" we used to call. The so-called quality of the car's equipment refers to the weight of the car after being fully equipped according to the factory technical conditions (such as spare tires, tools, etc.) and all kinds of oil and water are added. This is an important design indicator of automobiles. This indicator should be both advanced and practical.

What is the difference between the quality of automobile overhance and the total mass

1. Difference: Scope Total mass of the car = quality of the vehicle + quality of the driver and occupan + luggage quality, the scope of total mass of the car is larger.Indicator The quality of automobiles is closely related to the design level, manufacturing level and industrialization level of automobiles. And the emphasis on mass represents the sum of mass.

2. The total mass of the vehicle refers to the weight of a car when it is fully equipped and filled with passengers and goods according to regulations, and the quality of preparation is the weight of a car that people often say.

3. The scope of the total mass of the vehicle is wider. Vehicle quality refers to the quality of complete equipment of the vehicle, including the quality of lubricating oil, on-board tools, fuel, spare tires and other devices.

4. The total mass of the car minus the quality of the preparation is the quality of the people and goods loaded in the car. The total mass of the car refers to the weight of the car when it is fully equipped and filled with passengers (including drivers) and goods according to regulations.
