Abstract

PURPOSE: To improve the output characteristics of an engine by reducing the exhaust interference by opening separately a plurality of exhaust passages interposed with a catalytic converter containing monolith catalyzer with the surface of the catalyzer.
CONSTITUTION: In an exhaust passage of an engine body 1, in which and exhaust manifold 2 connected to one side of the body 1 is, for example, divided into upper and lower tubes 3 and 4 with a cylindrical casing 5 formed at the upstream side of the tube 4 and contained with monolith catalyzer 6 retained at both ends thereof via cushion rings 7 therein, exhaust tubes 8 to 11 divided from the tube 3 into four tubes and connected to the exhaust ports of the respective cylinders of the engine are independently formed to the bonded surface 13 of the tubes 3 and 4 via partition walls 12 to approach and face the upper surface 14 of the catalyzer 6 at the surface 13 to thereby independently open so as to thus reduce the exhaust interference among the exhaust cylinders
