Abstract: The purpose of this study is to develop a device for setting optimal parameters of a unit injector operation in diesel engines and to justify its design. The other goal is to create a hardware and software complex with a function of modernising the adjustment rigs. The study analyses factors that affect the law of fuel supply in the unit injectors. Findings from this analysis base the calculation methods and the regulation parameters of unit injectors. The adjustment parameters of the fuel supply system (cyclic design in particular) are calculated with regard to the injection chamber pressure using the suggested hardware and software complex.

Keywords: fuel system; unit injector; diesel engine; injection; indication; gas pressure; compression; expansion; simulation of injection.
