Abstract
PURPOSE: To obtain an exhaust pulsation effect in a wide range of rotaional frequency of an engine, by varying the length of exhaust pipes depending on the rotational frequency of the engine.
CONSTITUTION: Each large-diameter part 4 of a pair of exhaust pipes 2 is slidably fitted to a base mounting pipe 3 through a seal 5 and a spring 6. The base mounting pipe 3 is fixed on the engine 1. A connecting plate 7 is coupled to the casing 18 of a belt drive clutch 17 through a lever 15, a link 13, arms 12, 9 and a link 8. Therefore, the casing 18 is displaced in the axial direction depending on the rotational frequency of the engine 1, so that the exhaust pipe 2 is displaced in the axial direction through a coupling mechanism such as a lever 15 and thus the length of the exhaust pipe is varied. Thereby, the negative pressure wave of the exhaust pulsation is synchronized with the time of valve opening in a wide range of the rotational frequency of the engine. This raises the output.
