Diesel particulate filters |
摘要 |
A ceramic filter for trapping and combusting diesel exhaust particulates offering improved configurations that are significantly more resistant to thermal cracking and melting damage comprises a honeycomb filter body composed of porous ceramic material and including a plurality of parallel cell channels traversing the body from a frontal inlet end to an outlet end thereof, a portion of the cell channels are plugged in a non-checkered pattern, and the remaining cell channels are plugged in a checkered pattern. In one embodiment the honeycomb filter body has a section of non-checkered and a section of checkered plugging at the frontal inlet end. In another embodiment the honeycomb filter body has a plurality of cell channels internal plugs. In another embodiment the honeycomb filter body has a plurality of partial cell channels which extend partially from the frontal inlet end into the honeycomb filter body, and are unplugged at the frontal inlet end.
