Description
Summary:An innovative design of ceramic filter for diesel engine exhaust particulate matter is described. It is a cellular ceramic honeycomb with porous walls which act as the filter medium. Test results relating the effects of wall thickness, cell density, porosity, and filter volume on collection efficiency, pressure drop and filter capacity are described. Regeneration of the filter by ignition of the accumulated soot has been accomplished with conclusions drawn about the influence of exhaust temperature, oxygen content, and the effect of the filter design.
