Exhaust manifold for internal combustion engine |
摘要 |
An exhaust manifold connected to exhaust ports of at least three straightly-arranged cylinders of an internal combustion engine is constructed by a primary exhaust pipe which extends from the foremost cylinder of the cylinders in the rearward direction of the engine along the direction of the straight arrangement of the cylinders and a plurality of secondary exhaust pipes which extend from the other cylinders except for the foremost cylinder to the primary exhaust pipe. The secondary exhaust pipes are collected to the primary exhaust pipe so that downstream end portions of the secondary exhaust pipes are wound into the center axis of the primary exhaust pipe at a plurality of points on the center axis, respectively.
