摘要：The article presents the method of analysing the diagnostic informativeness of the parameters characterizing gas dynamic processes observed inside the working spaces of marine diesel and gas turbine engines.The entropy function was used as the measure of indeterminacy of the identified set of engine unserviceability states.Based on numerical simulation experiments of the analysed gasodynamic processes,the amount of introduced diagnostic information was assessed and the most adequate parameters for the technical state of the engine were selected.These parameters compose the minimised set of diagnostic parameters which make it possible to assess unmistakably the technical state of the examined working spaces.
