EXHAUST MANIFOLD-INTEGRATED MUFFLER COMPRISING MUFFLER BODY, PLURAL EXHAUST PORTS, FIRST PARTITION, AND SECOND PARTITION

摘要

Purpose: the comprehensive muffler of an exhaust manifold is arranged to the utilization rate for promoting the improvement of the efficiency of an engine and improving space by improving exhaust performance. Construction: the comprehensive muffler of an exhaust manifold includes that a silencer (3) whole circumstances appear and therein are formed in various sizes of semicylinder shape; Multiple exhaust ports (2) are independently connected directly to the outside of silencer; It is arranged the first subregion (5) of the semicylinder shape of the side of the inside of silencer; Second subregion (6), the smaller radius of radius with one to the first subregion. The inside of silencer is divided into the first, second, and third compartment (7,8,9) by first and second subregion. The multiple apertures (5a) of relatively smaller radius and multiple good hole (5b) are formed in the first subregion than the radius in hole. The multiple good hole (6a) of relatively smaller radius, the radius than the good hole of the first subregion are formed in the second subregion.
