Because there are many places in the engine in the form of pressure seal, this seal is generally about 1/3 load of the engine, only to play a full role, and there may be slight leakage in load hours. So engine manufacturers generally give emphasis. If the generator set runs under a small load, the following faults will occur over the running time:
1, the piston – cylinder liner seal is not good, oil channeling, burning into the combustion chamber, exhaust blue smoke.
2, for supercharged diesel engines, due to low load, no-load, low supercharging pressure. It is easy to lead to the reduction of the sealing effect of the supercharger oil seal (non-contact), and the oil enters the pressurization chamber and enters the cylinder with the intake air.
3, part of the oil to the cylinder is involved in combustion, some of the oil can not be completely burned, easy to form carbon deposits, and some are discharged with the exhaust. In this way, the cylinder liner exhaust duct will gradually accumulate oil, and carbon deposits will be formed.
4, the supercharger chamber oil accumulation to a certain extent, it will leak out from the supercharger joint surface.
5, long-term small load operation, will more seriously lead to the wear of moving parts, engine combustion environment deterioration, leading to overhaul in advance of the consequences.
