Title (EN) INTERNAL COMBUSTION ENGINE SOUND ISOLATION STRUCTURE
(FR) STRUCTURE D’ISOLATION ACOUSTIQUE DE MOTEUR A COMBUSTION INTERNE
(JA) 内燃機関の遮音構造
Abstract:
(EN) Provided is a sound isolation structure of an internal combustion engine capable of preventing propagation of a sound generated by an injector. The internal combustion engine sound isolation structure includes: a V-shaped cylinder block (101) having a right bank (1011) and a left bank (1012); a right bank air intake pipe (21) for supplying gas to the right bank (1011); a left bank air intake pipe (24) for supplying gas to the left bank (1012) and intersecting the right bank air intake pipe (21); in-cylinder injection injectors (11, 12) arranged in a surrounded space (29) surrounded by the right and the left bank and the intake pipe; and a sound isolation member (200) arranged in the surrounded space (29) between the in-cylinder injection injectors (11, 12) and the intersecting region (28).
(FR) La présente invention concerne une structure d’isolation acoustique d’un moteur à combustion interne capable d’empêcher la propagation d’un son généré par un injecteur. La structure d’isolation acoustique de moteur à combustion interne comprend : un bloc-cylindres en forme de V (101) qui possède un banc droit (1011) et un banc gauche (1012) ; un tuyau d’admission d’air de banc droit (21) pour fournir du gaz au banc droit (1011) ; un tuyau d’admission d’air de banc gauche (24) pour fournir du gaz au banc gauche (1012) et croiser le tuyau d’admission d’air de banc droit (21) ; des injecteurs d’injection intra-cylindre (11, 12) agencés dans un espace entouré (29) entouré par le banc droit et le banc gauche et le tuyau d’admission ; et un élément d’isolation acoustique (200) agencé dans l’espace entouré (29) entre les injecteurs d’injection intra-cylindre (11, 12) et la région de croisement (28).
(JA) インジェクタから発生する音が室内へ伝搬することを防止することが可能な内燃機関の遮音構造を提供する。内燃機関の遮音構造は、右バンク(1011)および左バンク(1012)を有するV型のシリンダブロック(101)と、右バンク(1011)に気体を供給する右バンク用吸気管(21)と、左バンク(1012)に気体を供給し、右バンク用吸気管(21)と交差する左バンク用吸気管(24)と、左右のバンクおよび吸気管に囲まれた包囲空間(29)に配置される筒内噴射用インジェクタ(11,12)と、筒内噴射用インジェクタ(11,12)から交差領域(28)の間で包囲空間(29)に配置される遮音部材(200)とを備える。
