Features of Supercharged Cummins Diesel Generator Set

In order to save energy and enhance work efficiency, most of the Cummins diesel generator sets are supercharged. In this article, Dingbo Power Generation Equipment will popularize for everyone what will happen to the supercharged engine of Cummins diesel generator set?

According to the analysis, when the Cummins diesel generator set is supercharged, the model load and thermal load are correspondingly large, and its components need to be strengthened accordingly. Many parameters have also changed to improve the performance of Cummins diesel generator sets and reduce pollution. The main changes are as follows:

1. The compression ratio is appropriately reduced, which is to prevent the explosion pressure from being too high after supercharging, so as to reduce the mechanical load and thermal load.

2. The fuel supply should be appropriately increased. Due to the increase in the intake air volume after supercharging, more fuel can be supplied for combustion. Therefore, the fuel supply is required to be increased to improve work efficiency.

3. The fuel supply advance angle is appropriately reduced, and the pressure and temperature at the end of compression after boosting increase, which shortens the fuel period, so the fuel supply advance angle should be appropriately reduced.

4. The fuel injection pressure is large to meet the large gas pressure in the cylinder, and the diameter of the nozzle hole of the injector is also increased to meet the needs of large fuel supply.

5. The overlap angle of intake and exhaust valves is increased, and the valve clearance is also increased. In order to improve the scavenging effect of the supercharged Cummins engine and increase the amount of charge, the angle of early opening and late closing of the intake valve and the exhaust valve is large, so the overlap angle is large. After supercharging, the working temperature of valve parts increases, the amount of expansion increases, and the valve clearance also increases accordingly.

6. The circulation area of the intake system and the exhaust system has been enlarged, and the structure and shape need to meet the needs of supercharging. The lubrication system and cooling system were also strengthened after necessary changes.
