    Abstract: The invention relates to a silencer being designed with sound absorptive material (13, 23) and a conduit section (1, 2) with one or more conduits (1) for leading gas flow into the silencer and with one or more outlets (2) for leading gas form the silencer. The sound absorptive material (13, 23) and the conduit section (1, 2) constitutes a protrusion extending from part of an outer shell (4) such as from an end cap (5, 6) constituting part of the shell for the silencer, or from an internal member, such as a baffle (9, 10) possibly separating at least two through-flowed chamber (12) of the silencer. Not-through-flowed cavities (17, 27) are arranged essentially adjacent to or at least partly surrounding said sound absorptive material (13, 23), thereby constituting one or more resonators acoustically communicating with said at least one through-flowed chamber. The silencer may also be designed so as to act as a spark-arrestor. Also, the invention relates to a combustion engine provided with such silencer.

    Abstract: A muffler for coupling to an exhaust port of an internal combustion engine. The muffler includes a housing having an exhaust inlet configured to receive exhaust gas from the engine, at least one internal expansion chamber and an outlet opening. The muffler further includes a diffuser cover attached to the housing over the exhaust opening of the housing forming an exhaust outlet of the muffler. The diffuser cover forms a trap chamber, a restricted throat and an ejector portion. The ejector portion is configured to draw in ambient air through an air inlet to cool the exhaust gas as it passes through the exhaust outlet. The restricted throat is positioned downstream from said trap chamber so as to increase the velocity of the exhaust gas as the exhaust gas passes through the restricted throat and into the ejector portion so as to aid in drawing in ambient air.
