Numerical study of the influence of the characteristics of fuel injectors on the ecological parameters of a diesel-generator

The paper presents the results of a systematic computational study to optimize the operation of diesel generator fuel injectors. The influence of the diameter of the outlet nozzle of the nozzle and the inclination of its axis, the taper angle of the spray and the injection advance angle on the local and integral characteristics of the operation of the diesel generator, as well as the values of emissions of soot, nitrogen oxides and underburning of fuel, has been investigated. It is shown that even with a slight optimization of the performance of the fuel injectors, it is possible to significantly reduce harmful emissions during the operation of a diesel generator.
