The purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, and injection rate, number of nozzle holes was investigated by using a quasi- dimensional model. In this work, the variety of injection rate is performed at various injection parameters, then performance and emission of the engine will be simulated. The aim of this work is finding the best injection system for a high efficiency and low NOx emission heavy duty diesel engine.
