The excavator burning oil is one of the more serious failures of the excavator engine. As we all know, the role of oil is mainly to lubricate and cool the engine. When the excavator engine burns oil, it is undoubtedly a dangerous signal to us. In fact, these are signs of wear of machine cylinders. How to solve the problem of oil burning of excavators? Master Feng of Yunnan Komatsu Excavator Repair Factory will help you solve it.
1. The piston ring and the inner wall of the cylinder liner are worn, resulting in excessive fit clearance and oil flowing up into the cylinder. As the air filter has not been cleaned for a long time, dust and impurities in the air enter the cylinder and wear the cylinder barrel piston. In addition, inferior diesel fuel may also form carbon deposits and impurities in the cylinder and wear the cylinder.
2. The air filter is blocked, which causes the engine air intake to be blocked and the engine oil to blow up into the combustion chamber, resulting in a sharp increase in engine oil consumption.
3. The supercharger and valve oil seals are damaged and not tightly sealed, and the oil enters the cylinder with the intake pipe.
4. Incorrect installation of piston ring. If the piston ring is not installed properly, it will cause the "oil pumping" phenomenon of the piston ring, so that part of the oil will flow into the combustion chamber and be consumed, and will also increase the wear.
5. The engine oil with wrong label is used, and the lubricating ability of the engine oil with too low viscosity is insufficient, which will aggravate the wear of the engine, scrape the piston ring unclearly, and burn the engine oil.
6. If the engine oil is not replaced for a long time, the impurities in the engine oil will increase, the lubrication performance will decrease, the wear of the cylinder block will be aggravated, and the sealing effect of the piston ring will be reduced.
Oil burning of excavator can be said to be one of the most serious faults. The phenomenon of oil burning will damage the vehicle's oxygen sensor too quickly, resulting in increased carbon deposition in the combustion chamber. In serious cases, the engine lubrication is insufficient, causing irreparable damage to the engine or even scrapping. Therefore, in order to ensure the normal operation of your machine, it is recommended to find a professional excavator master for maintenance!
