Title (EN) EXHAUST PIPE
(FR) TUYAU D'ÉCHAPPEMENT
(JA) 排気管
Abstract:
(EN) A portion of the outer pipe (70) of an exhaust pipe (10, 10A-10C), the portion being located closer to a muffler (56) than a catalyst (58), is configured as an outlet (84, 90, 96) from which purified exhaust gas discharged from the catalyst (58) is caused to flow to the muffler (56). One of the length (Lpa-Lpc) of the outlet (84, 90, 96), which is measured in the top-bottom direction, and the length (Lha-Lhc) thereof, which is measured in the left-right direction, is less than the diameter (D) of the catalyst (58), and the other is greater than the diameter (D) of the catalyst (58).
(FR) La partie du tuyau externe (70) d'un tuyau d'échappement (10, 10A-10C) située plus près du silencieux (56) que du catalyseur (58), est configurée sous la forme d'une sortie (84, 90, 96) à partir de laquelle le gaz d'échappement purifié évacué du catalyseur (58) est amené à s'y écouler vers le silencieux (56). L'une des longueurs (Lpa-Lpc) et (Lha-Lhc) de la sortie (84, 90, 96), respectivement mesurée dans la direction haut-bas et dans la direction gauche-droite, est inférieure au diamètre (D) du catalyseur (58), et l'autre est supérieure au diamètre (D) du catalyseur (58).
(JA) 排気管(10、10A~10C)の外管(70)における触媒(58)よりもマフラー(56)側の箇所は、触媒(58)から排出された浄化後の排気ガスをマフラー(56)に流す出口部(84、90、96)として構成されている。出口部(84、90、96)における上下方向に沿った長さ(Lpa~Lpc)及び左右方向に沿った長さ(Lha~Lhc)のうち、一方の長さは触媒(58)の直径(D)よりも短く、他方の長さは触媒(58)の直径(D)よりも長い。
