摘要： A vehicle, such as a straddle-type vehicle, can include an engine, a catalyst and an air cleaner. The catalyst can be disposed in an expansion chamber of the vehicle. At least a part of the air cleaner can be disposed above a swing arm of the vehicle, and at least a part of the expansion chamber can be disposed below the swing arm. The air cleaner can further be disposed to the rear of a shock absorber of the vehicle. Thus, the influence of heat from the catalyst and the engine on the air cleaner can be reduced. Consequently, efficiency of air induction into the engine can be increased, thereby improving engine output.

摘要： An exhaust system for an internal combustion engine, configured to enhance a silencing effect while being miniaturized. The exhaust system includes a muffler body configured in such a manner that a first expansion chamber and a second expansion chamber separated from each other are partitioned therein. A plurality of exhaust pipes extend from an internal combustion engine and are connected to the first expansion chamber. A communication pipe is configured to be connected to the first expansion chamber and the second expansion chamber, to merge exhaust gas from the plurality of exhaust pipes, and to introduce the merged exhaust gas into the second expansion chamber.

摘要： It is possible to simplify an internal structure of a silencer and it is possible to improve silencing performance while suppressing the increase of the size of the silencer. An exhaust pipe structure is constituted by an exhaust pipe (45) which is connected to an engine (4), and a silencer (43) which is disposed under the engine. A silencer inlet (43a) through which exhaust gas is introduced into the silencer is provided in the silencer and at the rear of a vehicle body. The exhaust pipe has a rear portion reversal pipe (62) by which a direction of an exhaust stream flowing rearward is reversed into a frontward direction. A downstream end side of the rear portion reversal pipe is connected to the silencer inlet. A silencer outlet (43b) through which exhaust gas is discharged from the silencer is provided in the silencer. The silencer outlet is provided at the front of the vehicle body. Thus, exhaust gas can flow inside the silencer unidirectionally from the rear toward the front.

摘要： In an exhaust muffler using a double communicating tube as a communicating tube between expansion chambers, the exhaust muffler controls exhaust gas so as not to flow directly between intake and exhaust ports of an inner communicating tube and an outer communicating tube to thereby utilize the volume of the expansion chamber sufficiently. On one end side of the double communicating tube facing into a second expansion chamber, a distal end opening of the inner communicating tube functions as an intake port of an inside passage. A closing member for closing an end in the axial direction of an annular passage is provided in or in the vicinity of a distal end opening of the outer communicating tube. An exhaust port for opening the annular passage outwardly in the radial direction is provided between the closing member of the outer communicating tube and a first partition wall.
