Sažetak
The paper presents a thermodynamic property analysis of four essential operating substances in diesel engine cylinder process: air, liquid fuel, fuel vapour and combustion products. Only the most important thermodynamic properties of each operating substance were taken into consideration. It was observed that the most of the thermodynamic properties are highly dependent on the operating substance temperature. Due to lack of equations for the calculation of some operating substance’s properties, separate approximation polynomials were presented. Polynomial coefficients were calculated by using the individually developed numerical program. Changing of thermodynamic properties for all operating substances was compared with measurements from the available literature, and developed polynomial errors were displayed. For each thermodynamic property a separate sub-program was developed, and it is possible to use these sub-programs directly in diesel engine numerical simulations. The accuracy of the diesel engine numerical simulation primarily depends on the exact calculation of the operating media thermodynamic properties, what ensures high applicability of the conducted analysis.
