摘要： An engine system and method of operating the same includes a two stroke engine, an exhaust manifold coupled to the two-stroke engine, a tuned pipe coupled to the exhaust manifold coupled to the exhaust manifold, a stinger pipe coupled to the tuned pipe, a silencer coupled to the tuned pipe and an exhaust pipe, and an exhaust bypass valve. Exhaust gases are directed from the two stroke engine through an exhaust manifold and through a tuned pipe. An opening of the exhaust bypass valve is changed to redirect exhaust gases away from the tuned pipe to change a pressure within the tuned pipe. In response to changing the opening of the exhaust bypass valve, the airflow through the engine is changed.

摘要： A vehicle is shown such as a snowmobile, where a frame includes a tunnel and a front frame portion comprised of cast halves. A suspension system is comprised of upper and lower control arms connected to the front frame portion. Some of the frame components are adhesively fixed together. A powertrain is supported by the frame, and is comprised of an engine and a clutch. The clutch includes a clutch guard supporting an oil container. The engine has an exhaust system which extends through the front frame portion. The snowmobile also has a rear snow deflector.

摘要： An exhaust system includes a housing comprising a first housing portion and a second housing portion separated by a common wall. The first housing portion has a first exhaust passage therethrough. The first exhaust passage has a first inlet receiving exhaust gasses from a turbocharger. The second housing portion has a second exhaust passage therethrough. The second exhaust passage has a second inlet receiving gasses from an exhaust bypass valve. The first passage and the second passage are non-intersecting within the housing.
