Abstract: This 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 Units (CPU) in diesel engines. The application of this method to research and conceptualise engine design allows us to choose an optimal combination of the CPU parameters and diesel engine control. As a result, an admissible level of thermal stress in the CPU and low fuel consumption are achieved. The method was practically used for upgrading high-speed diesel engines of the trademarks CHN 16.5/18.5, BMD and D20.
Keywords: diesel engines; thermal stress; in-cylinder processes; low fuel consumption; mathematical modelling; cylinder piston units; engine design.
