A Developed Quasi-Dimensional Combustion Model in Spark-Ignition Engines

Proceedings of the World Congress on Engineering 2008 Vol II WCE 2008, July 2 - 4, 2008, London, U.K., 2008. 5 p.Abstract - Computer simulations of internal combustion engine cycles are desirable because of the aid that they provide in design studies, in predicting trends, in serving as investigations tools, in giving more data than are normally accessible from experiments, and in helping to understand the complex process that occur inside combustion chamber such as auto-ignition and etc. The model developed in this work concern to the combustion of a 4-stroke, single cylinder, Ricardo E6 research engine and is the first step in developing of a comprehensive program aimed at accurately simulating spark ignition engine combustion over a wide range of operating conditions. The accuracy of the present model is confirmed by comparison with experimental result that have established by the effect of engine-operating conditions on the model outputs. The influences of engine-operating variables on the model outputs are components of a parametric study.
