Abstract

PROBLEM TO BE SOLVED: To reduce lowering of an engine output through improvement of a muffling effect and reduction of the occurrence of exhaust resistance by mounting a conical partition wall. SOLUTION: A conical partition wall is attached at the central part of a cylindrical muffler body and a pipe is arranged at an entrance in combination with connection. A sectional area through which exhaust gas in a muffler flows is extended through the inside from the outside of the conical partition wall and is gradually decreased toward an outlet. This constitution uses an object shaped in a manner that a trumpet-form cylinder, such as a megaphone and brass winds, is brought into an inverted state, performs reasonable muffling, further improves a muffling effect than a conventional type, where a difference in a sectional area is extremely high, only by mounting the conical partition wall, reduces the occurrence of exhaust resistance, and suppresses lowering of an engine output. Further, structure is also simplified and save of space is expected.

By utilizing this principle, a conical partition is attached, the structure is simplified, and the muffler is space-saving. The structure has a conical bulkhead in the center of the cylindrical silencer body and a pipe at the entrance and exit. The cross-sectional area of the exhaust inside the silencer should be gradually reduced from the outside to the inside of the conical bulkhead to the outlet. This principle uses a trumpet-shaped tube of a megaphone or brass instrument in reverse, so that it can be silenced without difficulty. In addition, compared with the conventional type where the difference in cross-sectional area is large,
By simply adding a conical partition, the noise reduction effect is increased, the exhaust resistance is reduced, and a decrease in engine output is suppressed. And the structure is simple and space saving can be expected.
