The performance and emissions optimization on multiply injection strategy by a DoE-based method in a common rail heavy duty diesel

The DoE (Design of Experiments)-based calibration method that incorporates models is called MBC (Model Based Calibration) and accomplishes modeling and optimization with MATALAB Toolbox- MBC Model Fitting and MBC Optimization. This methodology is provided with less calibration time as well as identical accuracy of measurement. This paper presents a DoE-based experiment to investigate the effects of the injection timing, rail pressure, pilot injection timing and pilot injection quantity on performance and emissions of a common rail heavy duty diesel, find out the optimal combination of such parameters.
