Abstract

PURPOSE: To eliminate interference due to pulsation of exhaust gas pressure by grouping a number of passages for monolithic catalyst to make a part of individual exhaust gas passages.
CONSTITUTION: The first branch pipe 20 communicated to the first cylinder and the fourth branch pipe 26 communicated to the fourth cylinder are made to converge to the first compound passage 70 built up of a partition wall member of an exhaust maniford 28 while the second branch pipe 22 communicated to the second cylinder 6 and the third branch pipe 24 communicated to the third cylinder 8 are made to converge to the second compound passage 72 built up of a partition wall means 74. The two compound passages 70 and 72 are opened close to the upstream end 48 of a monolithic catalyst as passages separated from each other. A number of small paths of the monolithic catalyst 16 are divided into a small path group A communicating to the first compound passage 70 and a small path group B communicating to the second compound path 72.
