Abstract
Environmental regulations of the vehicle have been tightened. In order to eliminate the deviation between the actual running and testing cycle, it must reduce soot in a wide operating range of the engine than the previous regulations. In recent years, model-based calibration has become common development method. However, it was difficult to get high accuracy model because soot has strong nonlinearity. In this study, we apply the quasi-stationary measurement in order to understand the properties of the soot. We propose a method for efficiently modeling of the soot. Effectiveness of the proposed method is shown through the experimental data.
