Improvement of PM Loading Prediction Accuracy in a Diesel Particulate Filter

-Construction of Model Parameter Fitting Method-

Abstract

For exhaust gas regulations of particle matter(PM), it is common to install a diesel particulate filter (DPF) in a vehicle with a diesel engine. To predict a performance includes pressure drop of the DPF, we had developed a physical based model of the DPF. In this study, we focused on the 4 model parameters and searched optimal values to minimize errors between simulations and experiments for some conditions by Fletcher–Reeves conjugate gradient method. And we report the results of the optimization.
