摘要： There is provided an exhaust device of a straddle-type vehicle. A first muffler body is arranged at one side, at which a drive chain is not arranged, in a region at the rear of a chamber. A second muffler body is arranged at another side, at which the drive chain is arranged. A first connection pipe interconnects the chamber and the first muffler body. A second connection pipe interconnects the chamber and the second muffler body. An exhaust control valve is configured to control a flow rate of exhaust air to circulate from an exhaust port toward the first muffler body via an exhaust pipe, the chamber and the first connection pipe. A part or all of the second connection pipe is formed to have a pipe shape by two or more plate materials, and has a non-true circular cross-sectional surface shape.

摘要： A muffler for an exhaust system of an internal combustion engine, especially for vehicles with hybrid drive, includes a muffler housing (12), a heat exchanger unit (48), arranged in the muffler housing (12), for transferring heat from combustion exhaust gas to a heat transfer medium, an inlet pipe (38), a first outlet pipe (52) and a second outlet pipe (40). A first exhaust gas flow path (54), in the muffler housing, routs exhaust gas through the heat exchanger unit (48) to the first outlet pipe (52). A second exhaust gas flow path (56), in the muffler housing, routs exhaust gas to a second outlet pipe (40), bypassing the heat exchanger unit (48). A flow path blocking/releasing device (58) for blocking and releasing at least one exhaust gas flow path (54, 56), of the first exhaust gas flow path (54) and of the second exhaust gas flow path (56).

摘要： A system according to the principles of the present disclosure includes an engine start module and an exhaust valve control module. The engine start module determines when an engine is started based on at least one of an input from an ignition system and the speed of the engine. The exhaust valve control module selectively fully closes an exhaust valve in an exhaust system of the engine when the engine is started to trap exhaust gas in the exhaust system.
