An Investigation on Injection Characteristics of Direct-Injected Heavy Duty Diesel Engine by Means of Multi-Zone Spray Modeling - 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 and number of nozzle holes were investigated by using a quasi-dimensional model. In the present work, the variety of injection rate is performed at various injection parameters where as performance and emission of the engine will be simulated subsequently. Finally the best injection system for a high efficiency and low NO emission heavy duty diesel engine was investigated.
