A ceramic filter which includes a plurality of end-plugged honeycomb structures which in combination act to trap and combust diesel exhaust particulates. The exhaust gas flows substantially equally through the end-plugged honeycombs. Preferably the ceramic filter includes two end-plugged honeycomb structures composed of a plurality of alternatingly end-plugged cell channels extending from an inlet face to an outlet face. The end-plugged honeycomb structures are arranged either parallel or perpendicular to the flow of the exhaust gas.

1. A diesel exhaust particulate filter apparatus comprising:an enclosure provided with an inlet cone and an outlet cone, wherein exhaust gas flows through the inlet cone and out the outlet cone; a first end-plugged honeycomb structure positioned adjacent the inlet cone, and a second end-plugged honeycomb structure positioned adjacent the outlet cone, wherein the first end-plugged honeycomb structure and the second end-plugged honeycomb structure are parallel to the flow of exhaust gas; wherein the first end-plugged honeycomb structure and the second end-plugged honeycomb structure are mounted end-to-end and off-center within the enclosure; means for separating the unfiltered exhaust gas entering the filter from the exhaust gas filtered by the first end-plugged honeycomb structure and the second end-plugged honeycomb structure.
