Because there were volvo generatormore diesel generator in the form of pressure seal, such as cylinder liner, piston, piston ring, supercharger, supercharger rotor shaft, this seal in the engine, about one-third of the load to give full play to the role, and the load hours there is slight leakage may occur. So the generator manufacturers at home and abroad generally gives emphasis in the manual. If the unit running under small load, as a continuation of the running time, can appear the following failures:

1. The piston - cylinder liner seal is bad, the oil is up, burning into the combustion chamber, the exhaust blue smoke.

2. For a turbocharged diesel engine, due to low load and no-load, boost pressure is low. Easy to cause the supercharger oil seal (non-contact) sealing effect to drop, the oil into the pumping chamber, along with the air inlet into the cylinder.

3. Up to the part of the cylinder oil burnt, part of the oil can't complete combustion, at the top of the valve, inlet, piston, piston ring, the place such as carbon deposit formation, and part with the exhaust. In this way, the cylinder jacket exhaust passage for oil will gradually accumulate, also can form carbon deposit.

4. The supercharger turbo indoor oil accumulation to a certain degree, is seeping from the combination of the supercharger surface.

5. Small load operation for a long time, will lead to the moving parts wear more serious, combustion engine overhaul period of early consequences such as environmental degradation. Diesel engine manufacturers at home and abroad, therefore, no matter the naturally aspirated type or booster type use low load/stress should be reduced by no-load running time, and the minimum load can not be less than 40% of the rated power of unit.
