The article describes the calculation of parameters of diesel fuel equipment on the nature of the change and the amount of fuel injection. Provides an implementation of the mathematical model of the fuel to be used when the kits before you install them on diesel and for calculation of parameters of parts used in the high pressure fuel pumps running on stands with a view to approximating the conditions of work in the booth to real conditions of a diesel engine and determine the correct performance of the pumps at the stand.

In the article the paper considers mathematical modeling of fuel equipment of high pressure and regulator of the rotation frequency of the crankshaft of the diesel engine. Analysis of factors affecting fuel equipment, mathematical modelling of the process of fuel into the cylinders, as well as mathematically describes the speed control of the crankshaft of the diesel diesel engine. Joint mathematical model of fuel equipment and rotation speed regulator. Presented algorithm and program calculation process the fuel feed to the cylinders of a diesel engine with a light hydraulic characteristics of generalized elements of fuel equipment and provision of the Executive mechanism of the regulator of the rotation frequency of the crankshaft of the diesel engine. In the work used mathematical and simulation, system analysis methods, the comparative method, methods of theoretical knowledge (formalisation), common logical methods and techniques of research (analysis, synthesis, classification, analogy ).
