Abstract :

A CFD simulation has been carried out to investigate the effects of combustion chamber geometry on engine performance and the amount of pollutant emissions in a 4-cylinder SI engine. The results obtained by the baseline case have been firstly validated with the experimental data and good results have been achieved. Totally, 23 different sketches of combustion geometries have been modeled and the effects of various parameters have been analyzed in detail. CFD simulation has been performed in MBT condition at 3000 rpm. The results show using the optimum sketch can reduce the amount of pollutant emissions while the other engine parameters remain constants.
