The paper presents the possibility of using a VCR engine as a driving unit of a generating set in rail vehicles. Thermodynamic analyzes of the engine were also performed. For the purposes of the research, the piston path was generated in the dynamic simulation in Solidworks to study the processes occurring during the combustion process. This path was used to simulate the AVL Fire program for the same initial conditions. Different variants of the engine cam control with the same compression ratio were compared. The article analyzed the moment and the period of time that the piston remains in the Upper Dead Center (TDC).
