Determining the Polytrophic Exponent of the Process Occurring During the Working Cycle of a Diesel

The paper utilizes obtained experimentally indicator diagrams to determine the polytrophic equation exponents of the processes that occur during the diesel working cycle. The algorithm for calculating the angle of the start and end of the combustion process was proposed, along with the values of these exponents. The effect of the change of the position of the p – v diagram relative to TDC on the exponent values was investigated. The engine operated under stationary conditions.
