Introduction
The thermal calculation of the engine is used to determine the parameters of the working medium in the engine cylinder, as well as the estimated parameters of the working process, to evaluate power and economic indicators that allow assessing the power and fuel consumption.
The calculation method is based on the method of V.I. Grinevetsky, later improved by E.K. Mazing, N.R. Briling, B.S. Stechkin and others.
The task of dynamic calculation is to determine the forces acting in the mechanisms for converting the energy of the working medium into the mechanical work of the engine.
In the present work, thermal and dynamic calculations are performed for the rated power mode.
