Coated diesel exhaust filter with low pressure drop |
| abstract |
A coated diesel exhaust filter with a relatively low pressure drop across the exhaust system despite the accumulation of soot deposits is provided. The filter comprises a porous ceramic structure having an inlet end, an outlet end, and a plurality of gas inlet channels and gas outlet channels disposed between the inlet end and the outlet end, the channels being defined by a porous ceramic wall. It is separated. The catalyst is at least partially distributed within the porous ceramic wall of the structure and is more concentrated in the portion adjacent to the ceramic wall outlet surface than in the portion adjacent to the ceramic wall inlet surface. Yes. Both the inlet and outlet surfaces are substantially free of catalyst in order to maintain the gas introduction porosity at these surfaces. The resulting filter effectively treats nitrogen oxides, carbon monoxide and unburned hydrocarbons present in the exhaust gas stream, while exhausting even when soot deposits accumulate on the inlet surface of the ceramic wall. Conveniently, the pressure drop across the system is relatively low. |
