Purpose: The qualification of influence of received step of analysis in numeric calculations on the value and distribution of the temperature in the inlet and outlet valve in the turbo Diesel engine in initial phase its work. Design/methodology/approach: The results of calculations of the value and distribution temperature in the valves in turbo Diesel engine received by means of the two zone combustion model and the finite element method. Findings: The carried out calculation present, that the selection of the step of analysis in the finite element method by used of the variable values of the boundary conditions and temperature working medium in the engine cylinder influences on the value and the temperature distribution on individual surfaces of the valves. Research limitations/implications: The modeling of the heat loads of the inlet and outlet valves was executed for two steps of the analysis in initial phase of the work of turbo Diesel engine. The obtainment the full opinion of the results of numeric calculations would require more operation for larger compartment of the time, until to the moment of achievement by the valves of temperatures during the stabilized work of engine. Originality/value: The results of numeric calculations of the heat loads of the valves displayed the large influence of the received step of analysis on achieved values and temperature distribution on individual surfaces these elements. This state the supplement of message on subject of course modeling the processes of flow of the heat and the same show on problem and way their running by use of the finite element method by means of variables values of the boundary conditions and temperature of working medium.
