- This paper presents a DI diesel engine combustion model based on double Wiebe equations approach. The aim of this work is to build a combustion model suitable for Hardware-in-the-Loop (HiL) simulations, and thus to be able to run in real-time applications. First, an ignition model is presented and correlated function of engine operating conditions. Then the combustion model parameters have been calibrated with a curve fitting technique with test bench experimental results. The calibration and validation process have been realized first on Matlab. Then the combustion model was coded in S-functions Simulink blocks suitable for HiL implementation. Offline test results for single injection cases with high engine speed (≻4000 rpm) are presented in this paper.
