Summary

In re-crystallized SiC segment filter made of coarse and fine grains, the amount of soot mass limit did not change when mean size of coarse SiC grains became larger. We found that the soot mass limit of the re-crystallized SiC filter segments which consisted of the coarse and fine SiC powder was not lowered even if the grain size of the coarse power was increased. the soot mass limit was kept constant at 12 g/L for the grains of 10 to 25 urn in size. During the investigation, we noticed that under the uncontrolled regeneration of the soot the maximum temperature, as well as the maximum temperature gradient, tended to be suppressed with increased grain size. the suppression of the maximum temperature can be considered desirable for a substrate as the catalyzed DPF (Diesel Particulate Filter).
