The engine oil burning of excavator is one of the more serious failures of excavator engine. We all know that the role of engine oil is mainly to lubricate and cool the engine. When the engine oil burning of excavator is undoubtedly a dangerous signal to us. In fact, these are all signs of machine cylinder wear. How to solve the problem of oil burning in excavators?
1. The piston ring and the inner wall of the cylinder liner are worn, resulting in excessive fit clearance, and the oil flows up into the cylinder. Because the air filter has not been cleaned for a long time, the dust and impurities in the air enter the cylinder and wear the cylinder piston. In addition, inferior diesel may also form carbon impurities in the cylinder and wear the cylinder.
2. The air filter is blocked, which leads to poor air intake of the engine, and the oil flows up the combustion chamber, resulting in a sharp increase in oil consumption.
3. The supercharger and valve oil seal are damaged and poorly sealed, and the oil enters the cylinder with the intake pipeline.
4. The piston ring is installed incorrectly. If the piston ring is installed improperly, it will cause the "pumping oil" phenomenon of the piston ring, so that part of the engine oil will flow into the combustion chamber and be consumed, and the wear will be aggravated.
5. The engine oil with the wrong grade is used, and the lubricating capacity of the engine oil with low viscosity is insufficient, which will aggravate the wear of the engine and make the piston ring scrape dirty, resulting in the burning of 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 be reduced, the wear of the cylinder block will be aggravated, and the sealing effect of the piston ring will be reduced.
It can be said that the engine oil burning of excavator is one of the most serious faults. The engine oil burning phenomenon will damage the vehicle 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 and even scrapping. Therefore, in order to ensure the normal operation of your favorite machine, it is recommended to find a professional excavator maintenance master for maintenance!
