EN The paper describes the basic methodological principles and the results of development and practical application of simultaneous complex parametric analysis of the in-cylinder processes and thermal load on cylinder piston unit in diesel engines. The application of the suggested method to research and conceptualize engine design allows us to choose an optimal combination of the cylinder-piston unit parameters and diesel engine control. As a result, an admissible level of thermal stress in the most heavily loaded parts of cylinder-piston unit and low fuel consumption of diesel engines are achieved. A limited number of factors determining perfect in-cylinder processes make this method easy to visualise as well as providing it with a clear physical meaning of graphically presented results, not restricting the analysis to the design parameters of engine units. The method was practically used for upgrading high-speed diesel engines of the trademarks CHN 16.5/18.5, CHN 15/18, and CHN 15/15, to increase their power based on the average indicated pressure, and to reduce their fuel consumption and harmful environmental effects. In particular, a method implemented in diesel engines CHN 15/15 of the basic design with their power increased by 60-70%, the power of diesel CHN 16.5/18.5 was increased by 70-100%.
