PURPOSE:To improve an output, by adoption a dual rear exhaust engine, longitudinally arranging a turbosupercharger behind a cylinder head of the engine, extending exhaust pipes almost linearly rearward and decreasing fluid resistance in the downstream side from a turbine outlet. CONSTITUTION:A turbocharger 34 is longitudinally arranged behind a dual rear exhaust engine 30 to connect an exhaust port outlet 31 of the engine 30 to an inlet 36 of a turbine 35 through a short exhaust pipe 32 extended rear upward. While an exhaust pipe 38 almost linearly horizontal as viewed from the side is connected to an outlet 37 of the turbine 35 and opened to the atmosphere in a rear part of the rider on a seat 15. Further a rear end of a wind inducting pipe 43 is connected to an inlet 42 of a compressor 39, while an outlet 45 is connected to an inlet 49 of an intake port 48 through an intake pipe 49 and equalizer tube 47. In this way, a constructional shape of the exhaust pipe 38 can be simplified while flow resistance in the downstream from the turbine outlet 37 can be decreased. |
