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 article presented the mathematical model of fuel heating of the high pressure pipeline of diesel engines fuel equipment and calculation results of temperature of its external surface at various temperatures air and the fuel equipment technical conditions.

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 ).

In this article, the main methods of technical diagnostics of diesel fuel equipment are considered. The faults they detect are listed. The principles of the methods work are examined in detail, the shortcomings and advantages of the chosen methods are revealed.

In article stages realization of complex systems non-contact thermal control of the main knots and systems locomotives are considered. The developed techniques of an assessment technical conditions sections refrigerators, electrical machines and the fuel equipment of a high pressure locomotives with use thermovision control method are presented.
