Abstract

PURPOSE: To make a dual muffler compact, reduce its maximum exhaust and heighten its silencing effect, by coupling mufflers which have exhaust bypasses, with each other.
CONSTITUTION: The exhaust pipes for a number of cylinders extend to two exhaust pipes P1, P2 extending through a muffler which is divided into a front and a rear sections by a partition plate 2 and have chambers C, D, E, F, divided from each other by partition walls 4a, 4b provided with small holes 3a, 3b. In the pipe P1, about a half of exhaust gas is conducted through a gas-permeable heat-resisting member 5a. The remaining exhaust gas enters into the chamber C through small holes 6c opend in front of the member 5a and flows into the chamber D through the hole 3a and enters again into the pipe P1 through small holes 6d opened behind the member 5a. After that, the exhaust gas is discharged. In the pipe P2, about a half of exhaust gas is likewise conducted through a gas-permeable member 5b. The remaining exhaust gas flows through small holes 6e, the chamber E, the hole 3b, the chamber F and other small holes 6f and is discharged through the pipe P2.
