Abstract

The Two-zone Thermodynamic models commonly used in SI ENGINEs consider Two regions, burned and unburned, with assumptions of equilibrium for products in the burned region; and ignoring nature of the flame. Using these models to predict the NOx EMISSION level, which is very important these days are not very accurate and the error in prediction is about 70%. In this Multi zone investigation, it is assumed that combustion of NATURAL GAS in the flame region is in equilibrium state, the product resulted from equilibrium combustion is considered by means of CHEMICAL KINETIC method with 13 species and 24 chemical reactions for non-equilibrium combustion to predict the NOx formation. This has lead to two different temperatures for flame and combustion products. In this method, the error of NOx prediction has reduced to 30%. In this work combustion products recirculation effects on engine performance is also considered. The developed results are compared with existing experimental results. In this way the accuracy is validated.
