The first hydro-gas-dynamic three-dimensional calculations of the combustion chamber of the designed engine were carried out. These calculations included two stages: at the first stage, the calculation was carried out for the engine dry motoring mode, taking into account valve movements, at the second stage, a combustion chamber with closed valves was simulated, that is, the valves did not move. Moreover, the simulation results of the first stage were used as initial conditions for the second one. This fact stimulated a considerable acceleration of the modeling process, due to the fact that the number of design elements was significantly reduced. As a result of the calculations, the first results of modification the fields of different physical quantities in the working cavities of the engine were obtained. Deficiencies in the design of gas exchange elements and a combustion chamber were revealed, and ways to solve these issues were determined.
