Beijing Woda Power Technology Co.. Ltd is a professional diesel generator set manufacturer with a history of more than 10 years. We have our own professional production lines, including open type diesel generator, silent generator, mobile diesel generator. etc.
Diesel generator sets run under small loads. As the running time continues, the following five major hazards will occur:
1. The seal between piston and cylinder liner is not good, the engine oil will go up, enter the combustion chamber for combustion, and the exhaust will emit blue smoke;
2. For supercharged diesel engines, due to low load and no load, the boost pressure is low. It is easy to cause the sealing effect of the turbocharger oil seal (non-contact type) to decline, and the oil will enter the booster chamber and enter the cylinder along with the intake air;
3. A part of the engine oil that goes up to the cylinder participates in the combustion, and a part of the oil cannot be completely combusted, forming carbon deposits on the valves, intake passages, piston tops, piston rings, etc., and the other part is discharged with the exhaust. In this way, engine oil will gradually accumulate in the exhaust passage of the cylinder liner, and carbon deposits will also be formed;
4. When the oil in the supercharging chamber of the supercharger accumulates to a certain extent, it will leak from the joint surface of the supercharger;
5. Long-term low-load operation will lead to more serious consequences such as increased wear of moving parts, deterioration of engine combustion environment, etc., leading to early overhaul period.
