V Order Logarithmic Polynomials for Thermodynamic Calculations in ICE 2001-01-1912

It is well-known that the reliability of calculations in ICEs depends on the accuracy of gases thermodynamic properties model. Several relationships modeling the composition of unburned and burned mixtures have been developed for computer use.
In this paper, the authors have determined new relationships suitable also for ICEs applications, in order to calculate the enthalpy for various gases, and mixtures.
These relationships can be used in the models describing the processes of intake, compression, combustion and expansion, to simulate a complete engine cycle and to foresee engine performance.
These relationships have the functional form of a “V order Logarithmic Polynomial”, and they can be used in temperature range of practical interest.
