The article presents considerations regarding the movement of the charge in the intake system and in the combustion chamber. It is assumed that both the geometry of the intake ports and the shape of the combustion chamber fundamentally determine the quality of the prepared mixture. A mathematical model was used to describe the movement of the charge during the filling process. An analysis of the influence of the combustion chamber geometry for four compression-ignition engines at four different engine speeds on the radial and axial velocities of the charge was conducted.Analyzing the directions of development in issues related to the optimization of the combustion process in diesel engines, the main criteria should include the improvement of characteristic engine performance indicators along with a simultaneous reduction in the emission levels of harmful exhaust components.
