Specific Reasons For Insufficient Diesel Combustion In Diesel Generators

Aug. 19, 2023

When the diesel generator set of Shangchai is working, sometimes the phenomenon of high exhaust temperature and black smoke occurs, which is mainly caused by insufficient combustion of diesel oil. So what are the reasons for insufficient diesel combustion?


1. The diesel engine is overloaded. If the diesel engine is under overload for a long time, the fuel supply will increase, resulting in insufficient diesel combustion, which can be solved by appropriately reducing the speed.


2. Diesel engine holding tile. Locking shoes are often encountered during mechanical operation. When the loaded crankshaft and the main bearing shoe are locked, the load of the diesel engine will increase, and the power consumption will also increase, which will lead to an increase in the amount of fuel and the phenomenon of black smoke. If the diesel engine suddenly becomes dull and emits black smoke, pay attention to whether there is a sticking tile.


3. The fuel supply of the fuel injection pump is too much. If the fuel injection pump injects fuel too fast, the fuel supply will increase, resulting in insufficient diesel combustion, resulting in black smoke. Adjust the fuel volume adjustment screw and reduce the fuel supply to solve the problem.

4. The fuel supply is too slow. Too fast oil supply will cause black smoke from the generator set, and too slow oil supply will also cause this group of situations, but the reasons are different. Diesel is easy to volatilize. If the fuel supply is too slow, the diesel will volatilize into the exhaust port before it is completely burned in the cylinder, which will cause black smoke to burn in the exhaust port. Therefore, in this case, it can be solved by appropriately increasing the fuel supply.


The above is the reason for the insufficient combustion of diesel fuel caused by black smoke from the operation of Shangchai diesel generator set analyzed byGuangxi Dingbo Generator Set Manufacturing Co.,Ltd.
