Does Audi q7 burn engine oil?

Audi vehicles do have excessive fuel consumption.

The reason is:

1. In order to increase the power, the cylinder wall of the engine has a mesh grid to increase the oil storage and achieve high lubrication. On the other hand, the sealing performance of the mesh oil storage grid is slightly weak, resulting in a small amount of oil loss to the combustion chamber.

2. Audi, including other German cars, has higher engine compression ratio than other cars, so the temperature of the engine is higher when it works, and the temperature of the turbocharged engine will be higher. If the high-temperature stability of the oil is poor, it will cause the oil to evaporate and accelerate the oil consumption.

3. Domestic congested road conditions and inferior fuel lead to excessive carbon deposition, and the gap between the piston and the cylinder wall of the German engine itself is large, so the piston ring has good toughness but weak tension. If the cleaning ability of engine oil is not strong, the carbon deposit on the piston can not be cleaned in time, which will increase the wear of cylinder wall and reduce the sealing performance, making it inevitable to burn engine oil.

Therefore, choosing good engine oil can alleviate the problem of burning engine oil in Audi cars.

Extended data

main feature

The engine is the heart of a car. There are many metal surfaces rubbing against each other in the engine. These parts have fast moving speed and poor environment, and the working temperature can reach 400℃ to 600℃.

The brand-new PurePlus technology can make natural gas into crystal pure synthetic base oil, and on this basis, add unique power cleaning technology to create lubricating oil with super clean and protective performance.

As a kind of machinery, engine has the same requirements for lubricating oil as general machinery, such as proper viscosity, certain performance requirements such as oxidation resistance, wear resistance, corrosion resistance and viscosity temperature.

Fuel saving and emission reduction

Although Audi's TDI diesel engine is very energy-saving and clean, the fuel consumption saving effect of this hybrid model is also considerable. Compared with ordinary Q7, the fuel consumption of hybrid Q7 is reduced by 23%, from 100 km 13 to 10 liter.

In addition, through the use of electric motors and other improvements, the carbon dioxide emission of the 3.6-liter engine has also been reduced from 309 g/km to 237 g/km.

engine

The new Audi Q7 released the diesel-powered version for the first time in China. This Audi 3.0LTDI engine adopts VTG variable cross-section turbocharging technology and fuel rail direct injection technology with piezoelectric ceramic nozzle, which obviously improves the engine performance.

Strong low-speed torque output makes the new Audi Q7 show strong speed-up ability at different speeds. It only takes 8.5s to accelerate from standstill to 100km/h, and the comprehensive fuel consumption is only 9. 1L/ 100km.
