Abstract:
Spray model of KIVA-II code was modified by comparing with experimentally measured spray liquid phase penetration and spray image in a transparent engine. The KIVA-II code with modified spray model was applied to a HSDI engine with different combustion chamber shapes, nozzle specifications and injection pressures. The results were compared with experimental emissions and it was found that the modified KIVA-II code was relatively able to predict the effects of engine design factors such as combustion chamber shape and injector on NOx and soot emissions.
