If the diesel generator sets are operated at a small load, the following faults will occur as the running time continues:
1. Piston - cylinder liner seal is not good, oil channeling, into the combustion chamber, exhaust to take the blue smoke.
2. For the supercharged diesel engine, due to low load, no load, boost pressure is low. Easily lead to supercharger oil seal (non-contact) of the sealing effect decreased, oil fleeing into the pressurization chamber, along with the intake air into the cylinder.
3. Part of the oil channeled to the cylinder involved in the combustion, part of the oil can not be completely burned in the valve, inlet, piston top, piston rings, etc. to form carbon deposition, and some are discharged with the exhaust. In this way, the exhaust gas cylinder liner will gradually accumulate oil, but also the formation of coke.
4 supercharger pressurized indoor oil accumulation to a certain extent, will be from the supercharger at the junction surface leakage.
5. Long-term small load operation, will lead to more serious wear and tear of moving parts, the engine combustion environment deterioration leading to the consequences of overhaul period ahead.
Therefore, foreign diesel engine manufacturers, regardless of the nature of the suction or supercharger models are stressed that the use should be to minimize the load / no-load running time, and provides the minimum load can not be lower than the unit rated power of 25% -30%.
