摘要： A muffler devised particularly for a small, reciprocating-piston two-stroke internal combustion engine of the type used on unmanned aerial vehicles. The muffler comprises a body incorporating an inlet, an outlet, and a plurality of chambers for exhaust gas flow from the inlet to the outlet. The body is configured to present a compact profile for installation on the engine. The chambers are so configured that adjacent chambers communicate to facilitate exhaust gas flow from the inlet to the outlet via flow passages. The various chambers comprise an inner chamber, an outer chamber, and one or more intervening chambers disposed between the inner and outer chambers. The various chambers are disposed one about another in annular formation. This arrangement creates a long flow path from the inlet to the outlet incorporating various directional changes.

摘要： A system for treating exhaust gas from an engine is disclosed. The system may include a housing, a fluid treatment element, and a conduit. The housing has an inlet and an outlet port and defines a flow path therebetween. The fluid treatment element is arranged in the flow path. The conduit is fluidly connected with at least one of the inlet port and the outlet port and includes a first port having a first axis and a second port having a second axis substantially perpendicular to the first axis. The first port has a first cross-section with an inner diameter. The second port has a second cross-section with an inner width and an inner length. The inner length of the second cross-section is smaller than the inner diameter of the first cross-section, and the inner width of the second cross-section is greater than the inner diameter of the first cross-section.
