After the wear of the oil outlet valve, on the one hand, the clearance between the pressure reducing ring and the inner hole of the valve seat becomes larger, the sealing becomes worse, and the pressure reducing effect becomes worse; On the other hand, the remaining pressure in the high-pressure fuel pipe is too high, causing an increase in fuel supply, causing fuel detonation and knocking the cylinder. The knocking sound is particularly noticeable when the throttle is reduced.
Repair assembly errors:
When repairing the wrong assembly, the piston pin snap ring is missing or not completely installed. When the diesel engine is working, the piston pin blows out and scratches the cylinder liner, causing cylinder pulling. The cleaning work is poor during installation, and bringing metal chips or hard debris into the cylinder can also cause cylinder pulling. In addition, the wrong installation, reverse installation and missing installation of piston ring can cause cylinder pulling. piston ring can be divided into oil ring and gas ring, and the oil ring is mainly used to scrape oil, Improve the lubrication condition of the cylinder liner. The gas ring is mainly used to ensure the sealing between the piston and the cylinder liner. According to the different working conditions and pressure bearing, the material selection and structural design of each gas ring are different. If the piston ring is installed incorrectly, reversely or missing, it can lead to untight sealing or no oil scraping effect, which worsens the lubrication condition of the inner surface of the cylinder liner and causes the cylinder to be pulled due to lack of oil
