ABSTRACT
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).
