<p>PURPOSE:To make foreign substances in exhaust difficult or impossible to be exhausted to the atmosphere, by installing a porous member inside the expansion chamber installed in an exhaust passage, while making the exhaust passage at the upstream side of the expansion chamber open to the porous member face-to-face. CONSTITUTION:Exhaust, inclusive of foreign substances, emitted out of a two-cycle engine passes through a passage pipe 13 and flows into an expansion chamber as shown in an arrow A with oblique lines. At this time, since the passage pipe 13 is opened to a porous member 16 face-to-face, the exhaust is blown to the porous member 16. Therefore, this exhaust is made contact with the porous member 16 whereby foreign substances including lubricating oil or the like are caught, thus they are separable from the exhaust.</p> |
