What does "increased engine oil" mean on the Internet? Why is there an increase in oil?
The phenomenon of increasing engine oil often occurs in self-injection engines, mainly due to the wet wall effect of unburned fuel on the inner wall of the cylinder, because there is a certain gap between the piston ring and the inner wall of the cylinder. During the operation of the machine, this oil film will be scraped back to mix with the lubricated oil and flow into the oil pan. If this part of engine oil cannot enter the evaporation box for a long time, it will lead to an increase in engine oil. This phenomenon is common in cold weather. At the beginning, the inner wall of the cylinder is cold, and the engine computer will increase the fuel injection quantity and time to achieve the purpose of rapid warming-up, so that more fuel will not be completely burned. If an inexperienced driver starts driving without fully preheating the car at this time, he will stop after driving for a short distance, and the fuel mixed with engine oil will not enter the evaporation box and be consumed. Over time, the engine oil will accumulate more and more, forming a more obvious phenomenon of engine oil increase. This situation is more obvious in hybrid engines. After all, when the hybrid system is started, the engine is not working and the motor is working, so it will be more common to produce more oil. In addition, not only the weather, but also the road conditions are a factor, and traffic jams will occur on most urban roads. In the process of stopping the vehicle, the engine will run at a high speed for a period of time, and insufficient gasoline combustion will also lead to an increase in engine oil. It can only be said that the increase of engine oil is a common phenomenon in direct injection engine models, just to see if the increase will affect the normal work of the engine.
