Volkswagen burn oil, which is known to Volkswagen owners and other car owners. Although people all know that Volkswagen will burn oil, more and more people buy Volkswagen, and the sales volume in 2016 is far more than that of Japanese cars. Why does Volkswagen burn oil? Why does Volkswagen not want to solve the problem of burning oil? Why is it better to sell more?
In the engine cylinder processing, the public has a very high process, and its cylinder wall has a mesh shape (which can be seen by microscope). Why is it mesh? In fact, it was made by the public after finishing processing the cylinder and using the Yanyan sand strip to make the inner wall of the cylinder form a mesh processing knife mark with an angle of 30 ° between the horizontal line and the cylinder.
The tiny mesh in the cylinder is actually a "small oil depot" for storing oil. By storing oil, the cylinder can obtain better lubrication performance when the piston works, it can minimize the wear between piston ring and cylinder wall.
Because the Volkswagen cylinder wall stores oil in a mesh, the residual oil in the mesh will burn off due to the increase of temperature when the piston is working. When this kind of cylinder is used in Europe, the speed is usually faster because of the good oil quality and good road conditions in Europe. However, when the engine runs at high speed, the oil remaining in the mesh will be reduced, so the oil burning is very small.
Why is burning oil so common in China? Because of the traffic jam in China and many traffic lights, vehicles need to stop and stop, making the engine often at idle speed, thus making more oil left in the cylinder mesh, so burning oil will be more common.
