Title (EN) FUEL INJECTION DEVICE
(FR) DISPOSITIF D’INJECTION DE CARBURANT
(JA) 燃料噴射装置
Abstract:
(EN) This fuel injection device is provided with: a pilot fuel injection section having a pilot fuel supply block and a pilot shroud; a main fuel injection section disposed so as to radially externally surround the pilot fuel injection section; and an intermediate air flow passage disposed between the pilot fuel injection section and the main fuel injection section. The pilot shroud includes a narrowed section which is located downstream of the pilot fuel supply block, and a flame holding section which surrounds a flame located downstream of the narrowed section. The flame holding section has formed therein an air injection slit from which compressed air from the intermediate air flow passage is injected in a direction along the inner peripheral surface of the flame holding section so as to cover the entire inner peripheral surface.
(FR) La présente invention concerne un dispositif d’injection de carburant qui est pourvu de : une section d’injection de carburant pilote comportant un bloc de distribution de carburant pilote et un carénage pilote ; une section d’injection de carburant principale disposée de façon à entourer radialement l’extérieur de la section d’injection de carburant pilote ; et un passage d’écoulement d’air intermédiaire disposé entre la section d’injection de carburant pilote et la section d’injection de carburant principale. Le carénage pilote comprend une section rétrécie qui est située en aval du bloc de distribution de carburant pilote, et une section de maintien de flamme qui entoure une flamme située en aval de la section rétrécie. Dans la section de maintien de flamme, une fente d’injection d’air est formée depuis laquelle de l’air comprimé provenant du passage d’écoulement d’air intermédiaire est injecté dans une direction le long de la surface périphérique interne de la section de maintien de flamme de façon à recouvrir la surface périphérique interne entière.
(JA) 燃料噴射装置は、パイロット燃料供給ブロック及びパイロットシュラウドを有するパイロット燃料噴射部と、前記パイロット燃料噴射部を径方向外側から囲むように配置されたメイン燃料噴射部と、前記パイロット燃料噴射部と前記メイン燃料噴射部との間に配置された中間空気流路と、を備える。前記パイロットシュラウドは、前記パイロット燃料供給ブロックの下流側の絞り部と、前記絞り部の下流側の火炎を囲む火炎保持部と、を含む。前記火炎保持部には、前記中間空気流路からの圧縮空気を前記火炎保持部の内周面に沿う向きに前記内周面の全周を被覆するように噴射する空気噴射スリットが形成されている。
