Abstract
PURPOSE: To make an oxidizing atmosphere in the periphery of a first catalyst bed to oxidized carbon monoxide and hydrocarbon, and reduce nitrogen oxide in the center of the first catalyst bed and perform further oxidation and reduction in a second catalyst bed.
CONSTITUTION: An exhaust pipe 1 has an intermediate expanded part 4 between tapered parts 2, 3. An inner cylinder 5 is supported by stays 6, 7 in the exhaust pipe 1 between the upstream end 1a of the exhaust pipe and the expanded part 4, thereby defining a passage 15 between the inner cylinder and the exhaust pipe. The first and the secnod catalyst beds 8, 9 made of ternary catalyst are provided in the expanded part 4. A mixing portion 10 is formed between these beds. An annular chamber 11 is formed around the end 1a of the exhaust pipe to introduce secondary ari into the passage 15 through a pipe 13, a check valve 14 and an air cleaner 16. Numerous air inlet ports 12 are perforated through the exhaust pipe.
