Title (EN) FUEL INJECTION CONTROL DEVICE, FUEL INJECTION SYSTEM AND FUEL INJECTION VALVE
(FR) DISPOSITIF DE COMMANDE D'INJECTION DE CARBURANT, SYSTÈME D'INJECTION DE CARBURANT ET VANNE D'INJECTION DE CARBURANT
(JA) 燃料噴射制御装置、燃料噴射システム及び燃料噴射弁
Abstract:
(EN) A fuel injection system (100) includes a fuel injection valve (10), an ECU (11), a pressure accumulating vessel (12) and a fuel pump (13). The fuel injection valve (10) and the pressure accumulating vessel (12) are connected to one another by means of a supply passage (71), and high-pressure fuel is supplied from the pressure accumulating vessel (12) to the fuel injection valve (10) via the supply passage (71). The fuel injection valve (10) includes injection holes (21) for injecting fuel, and a high-pressure passage (22) for guiding high-pressure fuel to the injection holes (21). The high-pressure passage (22) connects the injection holes (21) to the supply passage (71), and a high-pressure orifice (72) which has a variable degree of restriction to allow the fuel flow rate to be adjusted is provided in the high-pressure passage (22). The degree of restriction of the high-pressure orifice (72) is set on the basis of the amount of fuel to be injected from the fuel injection valve (10) and the injection interval.
(FR) L'invention concerne un système d'injection de carburant (100), lequel système comprend une vanne d'injection de carburant (10), une unité de commande électronique (11), une cuve d'accumulation de pression (12) et une pompe à carburant (13). La vanne d'injection de carburant (10) et la cuve d'accumulation de pression (12) sont reliées l'une à l'autre à l'aide d'un passage d'alimentation (71), et le carburant haute pression est délivré par la cuve d'accumulation de pression (12) à la vanne d'injection de carburant (10) par l'intermédiaire du passage d'alimentation (71). La vanne d'injection de carburant (10) comprend des trous d'injection (21) pour injecter du carburant, et un passage haute pression (22) pour guider un carburant haute pression vers les orifices d'injection (21). Le passage haute pression (22) relie les trous d'injection (21) au passage d'alimentation (71), et un orifice haute pression (72) qui a un degré de restriction variable pour permettre au débit d'écoulement de carburant d'être réglé est réalisé dans le passage haute pression (22). Le degré de restriction de l'orifice haute pression (72) est établi sur la base de la quantité de carburant à injecter à partir de la vanne d'injection de carburant (10) et de l'intervalle d'injection.
(JA) 燃料噴射システム(100)は、燃料噴射弁(10)、ECU(11)、蓄圧容器(12)及び燃料ポンプ(13)を有している。燃料噴射弁(10)と蓄圧容器(12)とは供給通路(71)により接続されており、高圧燃料が蓄圧容器(12)から供給通路(71)を介して燃料噴射弁(10)に供給される。燃料噴射弁(10)は、燃料を噴射する噴孔(21)と、高圧燃料を噴孔(21)に導く高圧通路(22)とを有している。高圧通路(22)は、噴孔(21)と供給通路(71)とを接続しており、この高圧通路(22)には、燃料の流量を調整するべく絞り度合いを変更可能な高圧オリフィス(72)が設けられている。高圧オリフィス(72)の絞り度合いは、燃料噴射弁(10)からの燃料噴射量や噴射間隔に基づいて設定される。
