A Quasi-Dimensional Model of Diesel Engine Working Process in Hardware-in-the-Loop Simulation System

In order to simplify the model of diesel engine working process in Hardware-In-the-Loop simulation system and improve its real time operating performance, a quasi-dimensional model of diesel engine working process based on a new phase divided spray mixing model was formulated and developed. The software MATLAB/Simulink was utilized to simulate the diesel engine working process. The good agreement between experimental results and calculated results indicates that the quasi-dimensional model of diesel engine working process is reliable for predicting power, fuel consumption and emissions of diesel engine. It is concluded that the quasi-dimensional model of diesel engine working process was greatly simplified and the real time operating performance of simulation system was obviously improved by using this phase divided spray mixing model.
