Development and Validation of a Modeling and Calibration Method for Diesel-Like Multistage Combustion Based On a Modified Multi-Wiebe Function.

The stringent regulations of fuel consumption and exhaust emission require further refinement of the control strategy for diesel engines. In the future, the prediction of the in-cylinder combustion process will become necessary to achieve a more dedicated control performance. Hence, a more precise model able to run in a real-time application is required to predict the nature of multiphase Diesel combustion.
