Diesel generator sets of white smoke is actually refers to the moisture from the exhaust smoke or containing unburned fuel ingredient adequately, white smoke show liquid bead state, diesel generator sets white smoke can be divided into the following several ways:
1. Diesel generator set at first startup or cold machine, the exhaust pipe to take white smoke, because low temperature in cylinder in diesel generator set is formed by evaporation, the phenomenon is particularly common in the winter. Because of the cold winter weather, operation of the diesel generator set, diesel engine and the exhaust temperature is low, hot water vapor condenses into water to form a "white smoke".
2, The working process of the diesel generator set, the atomized diesel injection cylinder's failure to complete combustion was out, and the cause of incomplete combustion of diesel are:
(1) diesel generator set nozzle card die, pressure is not enough, poor diesel atomization;
(2) the air in the oil, diesel oil in water;
(3) diesel generator set oil supply too late.
Appeared above it in several situations, should check diesel generator sets nozzle, adjust nozzle or replacement; Check the oil, eliminate the air in the oil and use standard diesel;
3 Diesel generator sets have crack or cylinder head gasket is damaged, with the increase of cooling water temperature and pressure, cooling water into the cylinder. Exhaust of diesel generating units to form easy to form water fog or water vapor.
4 Diesel genset fuel delivery advance Angle is too small. On the piston to the cylinder before the injection cylinder fuel too little, mixture, forming a thin too late injection reduced the premixed fuel quantity, thus reducing the combustion velocity of fuel in the diesel generator set, burning end late, burning smoke form a large number of moisture.
5.Diesel generator sets the faults of fuel oil supply system. Later delivery time, fuel combustion time is short, available to fuel can't on work trip, full combustion diesel generator sets the exhaust valve opens, part of the fuel by the exhaust vent;
6.Diesel generator sets, injector needle valve in the open position jammed or injector pressure adjusting spring break; Since the fuel into the combustion chamber, add oil, burning is not good, most of the exhaust pipes
Diesel generator set, plunger matching parts wear, sealing is reduced, although when debugging meet the oil, but the operation of the diesel generator set, under the same camshaft speed, plunger moving unit length, reduced the volume of oil supply, so the amount of oil to reach regulation, will extend the diesel generator set, injection time, injection process such as that within the prescribed prolong jet fuel, and can't work on diesel generator set of complete combustion, and the exhaust vent.
