Claims

[Claims for Utility Model Registration] (1) A plurality of exhaust passage bodies connected to the side of the main body of a multi-cylinder engine for each cylinder, and a downstream side of each exhaust passage body connected to the side of the main body of the multi-cylinder engine, and a number of exhaust passage bodies smaller than the number of cylinders. a gathering part formed at the downstream end of the exhaust passage body so as to converge in the exhaust passage, one of the plurality of exhaust passage bodies being overlapped with one of the other exhaust passage bodies so as to intersect with each other. An exhaust manifold structure for an engine according to the above type, wherein one of the mutually intersecting exhaust passage bodies has a rib extending in a direction generally along the axis of the other exhaust passage body. . (2) A plurality of exhaust passage bodies connected to the side of the main body of the multi-cylinder engine for each cylinder, and the exhaust gas so that the downstream side of each exhaust passage body is collected into a number of exhaust passages smaller than the number of cylinders. a gathering part formed at the downstream end of the passage body, and two of the plurality of exhaust passage bodies, which are generally parallel to each other, are overlapped so that they intersect with one of the other exhaust passage bodies. The exhaust manifold structure for an engine includes a rib extending between the two exhaust passage bodies that are generally parallel to each other, and the rib extends from the center of at least one of the two exhaust passage bodies. An exhaust manifold structure for an engine characterized by extending to an outer position beyond the limit.
