徴とする内燃機関の排気浄化装置。 A filter is provided in the exhaust passage, in which a large number of exhaust gas distribution cells are formed substantially parallel to the exhaust flow, and the exhaust gas is distributed to adjacent cells through partition walls to collect exhaust particulates.
In the exhaust gas purification device for an internal combustion engine, the filter is divided into a plurality of parts along the exhaust passage, and the upstream filter is arranged so that the flow passage cross-sectional area of the central cell is smaller than that of the outer peripheral part. An internal combustion engine characterized in that the cells in the center of the downstream filter are formed in a high density, and the cells in the outer periphery of the downstream filter are formed in a high density so that the flow passage cross-sectional area of the cells in the outer periphery is smaller than that in the center. Exhaust purification device.
