Abstract

As part of the work, the piston path generated in the dynamic simulation in the Solidworks program was used to study the processes occurring during the combustion process. The simulation was carried out in the AVL Fire program for the same initial conditions. Different variants of the motor cam control were compared at the same compression ratio. In the analyzed article, the moment and period of time that the piston remains in the Upper Dead Location (TDC) were analyzed.
