Abstract

The recent engine equipped with various devices such as variable nozzle turbocharger, EGR or DPF can satisfy environmental regulations. However, introduction of many technologies causes ECU parameters to increase and engine system to be complicated, which makes determining optimum ECU setting with conventional calibration method difficult. For that reason, calibration method based on experimental engine models is taken notice. The objective of this study is construction of high robustness and high quality experimental engine models containing physical laws such as extended Zeldovich mechanism or soot formation theories. And it is shown that the models to which physical laws are applied have possibility to predict exhaust emissions qualitatively and have robustness to the number of measured data.
