Reasons Of Yuchai Generator Start Smoke Exhaust

Feb. 20, 2022

Yuchai generator start exhaust pipe does not smoke fuel system factors

1. Oil line system blockage: there is no oil in the tank, the switch of the tank is not opened or the gas hole of the tank cap is blocked, the oil line between the tank and the fuel injection pump is blocked, the diesel filter or the filter screen of the oil pump is blocked, and the nozzle hole of the fuel injector is blocked.

2. Air in the oil line system: there is a leak in the pipeline between the oil tank and the oil pump, which makes the air enter the oil line.

3. The low pressure oil circuit system is partially damaged: the relief valve in the low pressure oil circuit is not sealed, so that the low pressure oil circuit cannot maintain a certain oil pressure. The oil valve of the oil pump is stuck, the seal is not tight, the spring is broken, the piston of the oil pump is killed or the piston spring is broken, so that the piston of the oil pump can not pump oil; The wear of the plunger part of the fuel injection pump is too large, resulting in a large amount of internal leakage, so that the oil supply can not meet the need for starting; Fuel injector precision parts carbon deposition or sintering can not open nozzle; Too early or too late oil supply; Bad spray atomization and so on.


 Reasons Of Yuchai Generator Start Smoke Exhaust


(2) fuel system factors of grey smoke and white smoke discharged from exhaust pipe during starting. Diesel engine is not easy to start, the start of the ash smoke of the fuel system is due to: fuel injection pump supply too much or too little; Poor atomization of fuel injector and poor mixture forming quality; Cylinder pressure is too low, diesel fuel combustion conditions are poor. After the diesel engine starts, the exhaust pipe emits a large amount of white smoke, which means that the diesel fuel does not burn out, and the injection advance Angle is too small.

A. When the belt is too loose, it will shake and slip;adjust the belt tension or replace the belt.

B. The hanger is loose and vibrates during operation. Tighten it again.

C. Large coplanar error of pulley, re-check and ensure coplanar is normal.

D. The pulley nut is loosened or displaced, and then tightened again.

E. Foreign matter entering motor, impact fan deformation, shell stuck,

Handle foreign matter and replace engine when damaged.

F. Motor rotation is stuck due to bearing damage. Replace it

H. Please replace the noise generated by air flow during fan deformation and replace  a generator.
