Audi cars are designed to protect the engine and extend engine life by reducing the frictional resistance between the piston ring and the cylinder wall. An oil film will be formed on the cylinder wall, and part of the oil film will be burned away with the high-temperature combustion gas, so the engine oil is lost. More year-on-year.
1. The processing technology of the engine cylinder of Audi cars. The engine cylinder wall appears in a mesh shape under the microscope. Each of these small meshes is a "small oil reservoir" for storing engine oil. The piston is When the cylinder is running up and down, the lubrication performance is better than that of the flat cylinder wall, which also minimizes the wear between the piston ring and the cylinder wall.
2. The piston rings of Audi cars have better toughness and weaker tension than Japanese cars. Simply put, they are strong but have low elasticity. This matching naturally reduces the impact of the piston rings on the cylinder wall when they run up and down. The wear caused by Audi cars, so after the Audi car has traveled hundreds of thousands of kilometers, the wear on the engine cylinder wall is much smaller than that of other car series, and the engine can still maintain good working condition.
3. The engine is like the heart of a car. Ultimately, the engine oil burning is caused by a problem with the piston rings. Under normal circumstances, there will be 0.2L oil loss per 1,000km. If it exceeds too much, burning may occur. Engine oil. If there is a problem with the piston ring seal, the engine oil will follow the movement of the piston and sneak into the combustion chamber to participate in combustion, resulting in oil burning.
4. In order to extend the service life of the engine, the Audi car manufacturer caused oil burning.
Preventive measures for burning engine oil:
1. Use high-quality engine oil:
Engine oil is easily corroded and aged under long-term high temperature conditions, causing the oil film to become thinner. It is easier to escape into the combustion chamber to participate in combustion, so using high-quality engine oil can greatly delay this phenomenon
2. Pay attention to the cleanliness of the fuel oil circuit:
Fuel must be burned during the combustion process. Carbon deposits are indispensable, and carbon deposits are the root cause of some automobile failures, such as the aging of valve oil seals, the increase in piston cylinder wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits. Considering that The relationship between domestic oil products requires the help of high-quality engine oil and (PNF type) fuel additives. This is also the key to achieving a repair-free solution to oil burning.
