Novel Approaches to an Efficient Trap of Diesel Particulates and It's Regeneration 2000-01-1930
To develop the reliable and practical method for efficiently collecting diesel particulates and for its regeneration, novel approach with a pellet-packed bed was proposed. This trap has the labyrinths of the flow passage which favors inertial impaction to ceramic pellets, ensuring the required trap efficiency with a longer lifetime prior to clogging as long as the appropriate pellet diameter and trap size are selected. From the experimental results on a single-cylinder test engine, it is shown that the pellet-packed bed has smaller pressure loss during engine operation compared to the monolith filter. Also, the regeneration test was made using a peculiar system by pellet circulation in place of conventional oxidation of particulates. Based on the results, the feasibility of the pellet-packed bed for diesel particulate trap was demonstrated.
