Abstract

DC60 (21/01/53) exhaust system for the engine, which can reduce the weight of the muffler, the soundproof effect can be guaranteed. And prevent the leakage of exhaust gas The muffler has an inner cylinder which is positioned in the outer cylinder and is separated into several expansion chambers. Connecting passways for connecting expansion chambers are established between the outer and inner cylinders. The edges of both parts of Connected passages are in contact with the outer cylinder and are welded to that section.
