The excessive consumption of lubricating oil for diesel generators is also caused by various reasons. Only by finding out the specific cause can we troubleshoot the problem according to the cause. Once the problem is solved, two problems are solved, one is the problem of unit failure, the other is the problem of unit fuel consumption and rising costs. Let’s look at the causes of excessive oil consumption in diesel generators.
1. Mechanical cause: 1. Piston, piston ring and cylinder wall wear too large, too large clearance;
2. The piston ring is not elastic enough or stuck in the groove, and the seal is not tight;
3. Valve and rocker arm clearance is too large, oil channeling, valve duct wear, lubricating oil is sucked into the cylinder;
4. The pressure of the lubricating oil disc is too high, and the lubricating oil enters the cylinder through the exhaust gas circulation device;
5. Oil bath air filter oil pool oil level is too high, lubricating oil is sucked into the cylinder;
6. The piston ring is installed upside down or damaged, or the opening is located on the same side. Ii. Oil quality reasons: If the base oil composition of the internal combustion lubricating oil is too light or too wide, it will also lead to excessive consumption, so it is necessary to check whether the evaporation loss is qualified. When the user uses the diesel generator, once the consumption of lubricating oil is found to be too large, it must be timely to find the cause and troubleshoot. Only in this way can the unit be restored to normal operation. Hope the above introduction can bring reference to users.
