1. The air intake pipe is dirty
If the vehicle is often running in the dust and bad air quality road area, you should pay attention to clean the intake pipe to ensure that the air flow.If the intake pipe is dirty, the engine can not run in the normal output power range, it will speed up the engine wear and aging. So as little as possible to drive passing the dust and more areas, at the same time, you should pay attention to replace the air conditioning grid.
2. Crankcase has too much mud
During the operation of the engine, the high pressure unburned gas, acid, moisture, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall.So that it is part of the wear and tear of the metal powder mixed together to form sludge. A small amount of sludge can be suspended in the oil, when the sludge will be more from the oil when the precipitation, plug the filter and oil hole, causing the engine lubrication difficult, thereby increasing the engine wear.
