description: In the final qualifying work, the calculation of the working process of a 450 kW marine diesel engine with a rotation speed of 2300 rpm for use on a high-speed boat was carried out. In addition, a strength analysis of the main engine components was performed. The dynamic calculation included filling in the main dynamic table, calculating loads and constructing vector and expanded pressure diagrams for the main and connecting rod necks, as well as their corresponding bearings, and analyzing the engine balance. For this work, the Russian YaMZ-238 engine was chosen as a prototype, taking into account the specified rated power of 450 kW and its purpose for marine use. Additional parameters included the rotational speed, the ratio of residual gas pressure to atmospheric pressure, the temperature of the residual gases, and the ratio of heat utilization coefficients. The results of the calculation of the working process included the values of the main parameters (pressure, temperature, volume, heat capacity) at all significant points of the working cycle, as well as indicator and effective indicators of the engine, its main dimensions and indicator diagrams. The calculation of the internal combustion engine systems was also carried out, the oil supply points to the connecting rod and main bearings were determined. The turbocharger system has been calculated.
