Diesel fuel injection system simulation

The injection process of a medium-speed diesel engine was studied in detail, using a computer program developed for this purpose. In the program, the injection pump was replaced with the measured pressure at the junction between the pump and high-pressure pipe. The results were calculated with a full and approximately a half load. The calculated and measured results corresponded moderately well with each other. In the calculation, special interest was paid to the flow of the injection valve holes. Most of the fuel was injected into the cylinder from the cavitating flow of these holes. During the after-injection, no cavitation occurred in the holes. Models of different hydraulic systems can be built from the components of the program.reviewe
