Abstract

In order to satisfy the validity demand of quasi-dimensional combustion model for predicting diesel engine performance, a new phase-divided spray mixing model is proposed in this work. The software MATLAB/Simulink is utilized to build the quasi-dimensional combustion model of diesel engine working process, and the performance for diesel engine is simulated. The comparisons between calculated results and experimental data show that the relative error of power and brake specific fuel consumption is less than 2.3%, and the relative error of nitric oxide and soot emissions is less than 5.8%. The good agreement between experimental results and calculated results indicates that the quasi-dimensional model of diesel engine working process which is based on the phase-divided spray mixing model is reliable for predicting power, fuel consumption and emissions of diesel engine.
