Abstract

PURPOSE: To heighten the purification effect, by mixing carbon monoxide, hydrocarbon and oxygen with one another in a first catalyst bed and oxidizing carbon monoxide and hydorocarbon in a second catalyst bed.
CONSTITUTION: An exhaust pipe 1 has an intermidiate 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 1 and the expanded part 4, thereby defining a passage 15 between the inner cylinder 5 and an exhaust pipe 1. The first catalyst bed 8 consisting of a peripheral oxidizing catalyst 8a and a central reducing catalyst 8b and a second catalyst bed 9 made of an oxidizing catalyst are provided in the expanded part 4. A mixing portion 10 is formed between these catalyst beds. An annular chamber 11 is provided around the end 1a of the exhaust pipe and connected to the atmosphere through a check valve 14 to introduce secondary air into the passage 15. Numerous secondary air inlet ports 12 are perforated through the exhaust pipe 1.
