What is the abnormal acceleration noise of Audi A6L?

The abnormal acceleration sound of Audi A6L may be caused by the cylinder valve. The regulating valve can be replaced, and the lack of oil may also cause similar problems. The oil pressure is relatively low, so it needs to be checked.

Precautions for engine maintenance:

1. Clean the air filter.

The air filter is directly related to the air intake of the engine when the car is running. The car only travels in the urban area, and the air filter will not be blocked. But if the car is driving on a dusty road, it is necessary to pay special attention to the cleanliness of the air filter.

The air filter is blocked or has too much dust, the air inlet of the engine is blocked, and a large amount of dust enters the cylinder, which accelerates the carbon deposition in the cylinder, hinders the ignition of the engine, and has insufficient power, which naturally increases the fuel consumption of the vehicle.

If driving on a normal city road, check the air filter when the car is driving 5000 kilometers. If there is too much dust on the filter, consider blowing compressed air from the inside of the filter element to clean the dust. However, the pressure of compressed air should not be too high to avoid damaging the filter paper.

There are many reasons for sludge at the throttle, some of which are carbon deposition at the throttle caused by exhaust gas from fuel combustion; In other words, impurities that are not filtered by the air cleaner will remain on the throttle. If there is too much oil, air intake will produce air resistance, which will lead to an increase in fuel consumption. In general, when the vehicle is driving 10000 to 20000 kilometers, the throttle should be cleaned.

2. Clean the carbon deposit on the fuel injector.

Because the combustion chamber is easy to produce carbon deposit, it will lead to difficulties in starting; Carbon deposition in the fuel nozzle will also lead to oil blockage, gasoline injection deformation, poor atomization, and fuel consumption will naturally increase.

In order to clean the combustion chamber, special carbon remover can be used to soften the carbon deposits on the combustion chamber and fuel nozzle and separate them from the surface of the parts, and then remove the softened carbon deposits. This method of carbon removal works well. Compared with the previous direct wiping, it has the advantage of no damage to the surface of parts and greatly improves the carbon removal efficiency.
