| Outline of Final Research Achievements |
The reduction of energy for regeneration of particulate filter for exhaust gas from internal engines is important issue on the improvement of total efficiency of internal combustion engines. The prediction of oxidation of soot particulate is strong tool for the optimization of the after treatment device. However, the accuracy of the conventional oxidation model, such as NSC model and Neoh model, is not sufficient for this purpose. In this study, the oxidation rates of soot particulates shock heated in a shock tube are measured by laser scattering technique at the various temperatures and oxygen fractions of surroundings. The measured oxidation rates of soot particulates are used to modify the model constants in the NSC and Neoh models. The modified NSC and Neoh models are coupled with each other for the prediction of soot oxidation rate. The predicted oxidation rates of soot particles by the modified model are agree with the measured one approximately.
