What is the cause of abnormal exhaust failure in diesel generator sets? Firstly, the supply angle of the injection pump is too small. When the fuel supply advance angle of the diesel generator set is too small, it will cause a delay in the injection of the fuel injector, making the diesel injected into the combustion chamber insufficient to burn out, which means that the exhaust smoke of the diesel generator set is severe after combustion. When the fuel supply advance angle is too small, the exhaust temperature increases, fuel consumption increases, and power shortage occurs. Secondly, if the fuel injector drips water, splashes oil or sprays poorly, it will cause a delay in the combustion time of the diesel injected with black smoke and malfunction in the combustion chamber.
If the sealing in the combustion chamber is poor, the amount of compressed air in the cylinder will decrease, and the temperature and pressure at the end of compression will decrease. The diesel injected into the combustion chamber cannot completely burn because it does not receive enough air, causing smoke from the exhaust pipe, and there are many factors that can cause poor sealing of the combustion chamber, such as excessive wear on the piston, piston rings, and cylinder liners, installation of piston rings, cylinder gasket leakage, and loose valve closure.
Perhaps the intake air volume of the internal combustion chamber is constant, because if the air filter is not properly maintained, and the internal coke combustion chamber increases, the exhaust pipe will be blocked or damaged in the turbocharger, which will cause the combustion of the original gas in the combustion chamber and affect the combustion of the diesel generator set. The amount of exhaust gas and free carbon generated from the exhaust pipe will be discharged. Finally, it was found that during the operation of the diesel generator set, if overloaded, it would lead to an increase in the amount of diesel fuel injected into the combustion chamber. Under the same amount of air in the combustion chamber, the phenomenon of insufficient combustion of redundant diesel fuel in the black smoke exhaust pipe would occur.
