In this project two main parts are investigated:
1- Developing a multi zone combustion model in order to determine quantities of produced emissions and power during a closed-cycle. Several in-cylinder processes such as spray development break up and evaporation, ignition delay, heat transfer, heat release and emission formation will be considered in the modeling. The model follows the formulas proposed by Hiroyasu for the spray phenomena and the spray is divided into many zones, for which the 1st law of thermodynamic and the state equation will be solved in order to obtain pressure and temperature history.
2- Implementation of an optimization algorithm on the combustion model results using genetic algorithm. This algorithm is a multi objective algorithm in which NOx and Soot (main diesel engine emissions) are minimized and IMEP, as a representative of engine performance, is maximized in a specific load and engine speed.
