Claims

[Claims for Utility Model Registration] 1. Metal converters 11, 27, and 28 each having a metal corrugated plate 13 carrying a catalyst wound around the axis Y-Y and housed in a stainless steel cylindrical case 12 as a converter. At the same time, the exhaust manifold is connected to pipes 14, 23, 15, 24, 16, 25, corresponding to each exhaust port of the engine.
17, 26, and the shape of the outlet side of these pipes is formed to match the shape of the inlet of the metal converter 11, 27, 28 divided by the number of pipes, and these pipes 14, 23, 15 ,24,
A joint structure of an exhaust manifold and a metal converter, characterized in that the outlet sides of the exhaust manifolds 16, 25, 17, and 26 are joined to the inlets of the metal converters 11, 27, and 28. 2. As a converter, a metal converter 11 is used, in which a metal corrugated plate 13 carrying a catalyst is wound around the axis Y-Y and housed in a stainless steel cylindrical case 12, and an exhaust manifold is connected to each exhaust port of the engine. Corresponding pipe 14
, 15, 16, 17, and between the outlet side of these pipes and the inlet of the metal converter 11, an outlet is provided in a shape matching the shape of the inlet of the metal converter 11 divided by the number of pipes. a connecting member 2 having a number of passages equal to the number of pipes;
1 is provided, and the outlet side of the pipe is connected to the inlet of the metal converter 11 via the connecting member 21, thereby connecting each pipe 14, 15, 16, 17 to the connecting member 2.
A joint structure between an exhaust manifold and a metal converter, characterized in that the exhaust manifold and the metal converter communicate with each corresponding passage. 3. According to claim 1 or 2, the pipes 23, 24, 25, 26 constituting the exhaust manifold are divided into several grooves 23, 26, 24, 25, and metal converters 27, 28 are provided corresponding to each group. A combination structure between the exhaust manifold and metal converter.
