Abstract
A thermodynamic model for the simulation of a spark ignition engine running on alternate hydrocarbon fuel is presented. This paper aims to develop a simple, fast and accurate engine simulation model without the need for a great deal of computational power or knowledge of precise engine geometrical data. The model is based on the classical two-zone approach, wherein parameters like heat transfer from the cylinder, blowby energy loss and heat release rate are also considered. The general fuel is specified by way of its C-H-O-N values. Curve-fit coefficients are then employed to simulate air and fuel data along with frozen composition and practical chemical equilibrium routines. The calculated data is then used to plot the various thermodynamic parameters with respect to crank angle.
