Title (EN) ENGINE WITH TURBO SUPERCHARGER
(FR) MOTEUR COMPRENANT UN TURBOCOMPRESSEUR
(JA) ターボ過給機付エンジン
Abstract:
(EN) An engine (1) with a turbo supercharger is provided with a first turbo section (3A) and a second turbo section (3B). A first upstream section (55U) which is the scroll starting point of a first scroll passage (55) of the first turbo section (3A), and a second upstream section (53U) which is the scroll starting point of a second scroll passage (53) of the second turbo section (3B) are disposed, respectively, on the side that is further than a first turbine shaft (37) and the side that is further than a second turbine shaft (38) with respect to an engine body (10). The first and second scroll passages (55, 53) are passages scrolled so that the downstream sides of the first and second upstream sections (55U, 53U) face the side that is closer to the engine body (10) than is the respective turbine shaft (38, 37), wherein the scroll passages scroll in opposite directions to each other. Consequently, a first turbine (33T) and a second turbine (35T) rotate in opposite directions to each other.
(FR) L'invention concerne un moteur (1) comprenant un turbocompresseur, lequel moteur comporte une première section de turbine (3A) et une seconde section de turbine (3B). Une première section amont (55U), qui est le point de départ de volute d'un premier passage de volute (55) de la première section de turbine (3A), et une seconde section amont (53U), qui est le point de départ de volute d'un second passage de volute (53) de la seconde section de turbine (3B), sont disposées, respectivement, sur un côté qui est plus loin qu'un premier arbre de turbine (37) et un côté qui est plus loin qu'un second arbre de turbine (38) par rapport à un corps de moteur (10). Les premier et second passages de volute (55, 53) sont des passages qui sont en volute, de telle sorte que les côtés en aval des première et seconde sections amont (55U, 53U) sont dirigés vers un côté qui est plus proche du corps de moteur (10) que ne l'est l'arbre de turbine respectif (38, 37), les passages en volute étant en volute dans des sens opposés l'un par rapport à l'autre. Par conséquent, une première turbine (33T) et une seconde turbine (35T) tournent en sens opposés l'une par rapport à l'autre.
(JA) ターボ過給機付エンジン(1)は、第1ターボ部(3A)及び第2ターボ部(3B)を備える。第1ターボ部(3A)の第1スクロール通路(55)のスクロール始点である第1上流部(55U)、第2ターボ部(3B)の第2スクロール通路(53)のスクロール始点である第2上流部(53U)が、各々第1タービン軸(37)、第2タービン軸(38)よりもエンジン本体(10)に対して遠い側に配置されている。第1、第2スクロール通路(55、53)は、各第1、第2上流部(55U、53U)の下流側が各タービン軸(38、37)よりもエンジン本体(10)に近い側に向かうようにスクロールした通路であって、互いに反対方向にスクロールしている。このため、第1タービン(33T)と第2タービン(35T)とは互いに逆方向に回転する。
