<p>PURPOSE:To uniformly accumulate soot, by providing blocking parts alternately in each cell end part of a honeycomb structure, consisting of porous ceramic having plural cells, while throttled parts in inlets of inlet exhaust gas passages. CONSTITUTION:This exhaust gas filter 1 alternately provides each inlet and outlet blocking part 8, 9 in the end part of a cell 2 in a honeycomb structure consisting of porous ceramic having the many cells 2. In this way, the cell 2 is divided into an inlet exhaust gas passage 6 and an outlet exhaust gas passage 7. And the above filter, forcing the inlet blocking part 8 to be fitted by pressure so as to provide a section larger than that of the outlet exhaust gas passage 7, spreads a cell wall end part. In this way, the filter, narrowing an inlet part 4 of the inlet exhaust gas passage 6 and introducing into the filter 1 exhaust gas 12 receiving resistance in the inlet part 4 and uniformly flowing into the inlet exhaust gas passage 6, uniformly accumulates soot 10 in the passage 6.</p> |
