Emission reduction is the key issue for modern engines engineering process. Therefore,
fuel injection equipment development based on ecological legislations is important today.
We performed modern diesel engine’s combustion simulation to determine the fuel injec-
tion process requirements. The field of engine design parameters included the following
values: number and diameter of the injector nozzles, the boot length and pressure of in-
jection, EGR ratio, start of injection (SOI) timing. Simulations were carried out for
modes according to ISO 8178-4 for the selected range of loads for marine engines. Based
on the findings recommendations were introduced for injection rate shaping using an
injector with an additional controlling section in the nozzle.
