Title: Diesel generator load is too low exhaust pipe drip details
Time: 2013/7/11 11:29:28
China diesel generator internal data network: Because there are many uses diesel pressure seal forms, such as cylinder liners - pistons - rings, the supercharger - turbocharger rotor shaft, the engine of this seal is generally about 1 / 3 load only when fully play its role, while the load hours there would have been a slight leakage. Therefore, foreign engine manufacturers in their manual generally given emphasis.

If the diesel generator set in a small load operation, with the continuation of the running time, the following failures:

A piston - cylinder liners sealed well, oil Shangcuan into the combustion chamber and exhaust blue smoke.

2 for supercharged diesel engines, due to low load, no load, the boost pressure is low. Easily lead to turbocharger oil seal (non-contact) the sealing effect is reduced, the oil fleeing plenum, along with the intake into the cylinder.

3 sneaked on the part of the oil in the combustion cylinder, part of the oil is not completely burned, the valve, inlet, piston, piston rings, etc. to form coke, and part of it is discharged with the exhaust. Thus, the cylinder liners exhaust ports will gradually accumulate oil, also the formation of coke.

4 plenum turbocharger oil accumulated to a certain extent, the turbocharger will be from leaking out at the joint surface.

5 Long-term low load operation, will lead to more serious moving parts wear and tear, deterioration of the environment as a result of the combustion engine overhaul period ahead consequences.

Therefore, foreign engine manufacturers both the naturally aspirated or supercharged models have emphasized the need to minimize the use of low load / no-load running time, and not be less than the specified minimum load unit rated power of 25% -30%.
