Abstract
During forced regeneration of a diesel particulate filter, it is important to set an optimal regeneration timing and duration in consideration of pressure loss and fuel efficiency. Generally, the relationship between regeneration period and pressure drop are predicted by numerical calculation, but depending on the conditions, the prediction accuracy during regeneration may not be sufficient. In this study, we proposed a reaction equation based on the Arrhenius equation and shrinking sphere model to improve the prediction accuracy. Finally, the relationship between regeneration temperature and time was revealed by the proposed model.
