    Abstract: A muffler for use with an internal combustion engine is provided. The muffler includes a first tube configured to receive a first exhaust stream. The first tube includes a first inlet portion, a first outlet portion spaced apart from the first inlet portion, and a first intermediate portion extending between the first inlet portion and the first outlet portion. The muffler also includes a second tube configured to receive a second exhaust stream. The second tube includes a second inlet portion, a second outlet portion spaced apart from the second inlet portion, and a second intermediate portion extending between the second inlet portion and the second outlet portion. The first intermediate portion and the second intermediate portion cross each other, are at least partially stacked on each other, and are in fluid communication with each other.

    Abstract: A muffler includes a shell, baffles, and a plurality of pipes. The shell defines first and second end cavities and a central cavity. The end cavities have larger cross-sectional areas that a cross-sectional area of the central cavity. The baffles cooperate to form multiple chambers within the shell. A first inlet directs a first portion of the exhaust into a first chamber. A second inlet directs a second portion of the exhaust into a second chamber. A first pipe extends through first, third and fourth baffles and includes an inlet in the fourth chamber. The first pipe directs exhaust from the fourth chamber to a first outlet at the first end cavity. A second pipe extends through the second, third and fourth baffles and includes an inlet in the third chamber. The second pipe directs exhaust from the third chamber to a second outlet at the second end cavity.

    Abstract: An exhaust gas aftertreatment device provided to an upper portion of an engine includes a right and left pair of first and second aftertreatment units, into which exhaust gas from the engine dividedly flows, each including a first exhaust gas emission control system on an upstream side, a second exhaust gas emission control system on a downstream side and a communication pipe through which the first and second systems are in communication with each other, the first and second systems, while being arranged side by side in a right-and-left direction, being oriented so that a flow direction of the exhaust gas flowing therein is parallel with a front-and-rear direction. When the device is seen in the front-and-rear direction, an outer linear envelope tangent to the first system and the communication pipe of each of the units extends upward while tilting toward a right-and-left center of the engine.

    Abstract: An exhaust system for exhausting multiple cylinders of a small engine, wherein the exhaust system includes a plurality of exhaust units is described herein. Each exhaust unit of the exhaust system is operatively and fluidly connected to a separate cylinder of the small engine such that the exhaust gases from each cylinder remain separated as they pass through different exhaust units of the exhaust system. The exhaust system includes a canister having opposing end walls to define a volume therein. The exhaust system further includes at least two exhaust units, and each exhaust unit includes an inlet that is operatively and fluidly connected to a cylinder of the small engine, a primary chamber within the canister into which exhaust gases are introduced by the inlet, a primary stage transfer tube located at least partially within the primary chamber for fluidly connecting the primary chamber with an outlet through which exhaust gases are exhausted from the exhaust system. Each of the exhaust units is separated by an inner chamber wall that is shared by adjacent exhaust units yet prevents fluid communication between the adjacent exhaust units.
