Abstract

PURPOSE: To suppress a rise of back-pressure and improve the power permitting the multicylinder engine where a honey comb catalyst is provided for an exhaust gas passage to prevent the downstream section of the honey comb catalyzer from an interference of the exhaust gas evolved from the multicylinders.
CONSTITUTION: An exhaust gas manifold 5 is constituting the branch pipes 5aW5b connected respectively with an exhaust port of the first to fourth cylinders 1W4 and a manifold 5e thereof, the exhaust gas passage 6 located between the exhaust gas manifold 5 and the exhaust pipe being provided with a honeycomb catalyst 7. The honeycomb catalyst 7 is formed by providing independently multi-streams 7c... from the upper stream 4a thereof to the downstream 7b. Said manifold 53 is, besides, provided with a division wall 10 which is semicircularly isolating the first and the second manifold passages 8 and 9 in order to collect the exhaust gas of the cylinders where an ignition order may not be continuous, the downstream thereof of the division wall 10 being joined with the upper stream 7a of said catalyzer 7.
