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, injection rate, number of nozzle holes were investigated by using a quasi- dimensional model. In this work, different injection rate is considered with various injection parameters and performance and emission of the engine is simulated.
The aim of this work is finding the best injection system for a high efficiency and low NOx emission heavy duty diesel engine.
