AB - This paper has illustrated a "near wall" combustion model for a spark  ignition engine that was included in a two-zone thermodynamic model. The  model has calculated cylinder pressure and temperature, composition, as well  as heat transfer of fresh and combustion gas. The CO submodel used a  simplified chemical equation to calculate the dynamics of CO during the  expansion phase. Subsequently, the HC submodel is introduced, and the  post-flame oxidation of un-burned hydrocarbon was affected by the  reaction/diffusion phenomenon. After burning 90% of the fuel, the  hydrocarbon reaction dominates at a very late stage of combustion. This  modeling method can more directly describe the "near wall" flame reaction  and its contribution to the total heat release rate.
