Title (EN) EIGHT-CYLINDER ENGINE
(FR) MOTEUR A HUIT CYLINDRES
Abstract: front page image
(EN)Even in a construction in which fuel injection valves for eight cylinders are energized by two EDUs, a sufficient charging time for each EDU can be ensured. In an eight-cylinder engine including fuel injection valves provided one for each cylinder of the eight-cylinder engine for injecting fuel thereinto, a first valve drive unit for driving four of the eight fuel injection valves to open and close by energizing these four fuel injection valves; and a second valve drive unit for driving four fuel injection valves other than the first-mentioned four fuel injection valves to open and close by energizing the second-mentioned four fuel injection valves, both of the valve drive units drive those fuel injection valves which are provided on cylinders for which combustion and expansion strokes occur at equal intervals. For example, the first valve drive unit (12) energizes those fuel injection valves which are provided on a first cylinder, a fourth cylinder, a sixth cylinder, and a seventh cylinder, and the second valve drive unit (13) energizes those fuel injection valves which are provided on a second cylinder, a third cylinder, a fifth cylinder, and an eighth cylinder.
(FR)MEme dans une construction dans laquelle des soupapes d'injection de carburant pour huit cylindres sont alimentEes par deux EDU, un temps suffisant de chargement pour chaque EDU peut Etre assurE. Dans un moteur A huit cylindres incluant des soupapes d'injection de carburant A raison d'une soupape pour chaque cylindre du moteur A huit cylindres pour injecter le carburant A l'intErieur, une premiEre unitE de commande de soupape pour commander A quatre des huit soupapes d'injection de carburant de s'ouvrir et de se fermer en alimentant ces quatre soupapes d'injection de carburant; et une seconde unitE de commande de soupape pour commander quatre soupapes d'injection autres que les premiEres mentionnEes pour que quatre soupapes d'injection s'ouvrent et se ferment en alimentant les quatre soupapes d'injection de carburant deuxiEmement mentionnEes, les deux unitEs de commande de soupape commandent les soupapes d'injection de carburant qui sont installEes sur des cylindres pour lesquels les temps combustion et de dEtente ont lieu A intervalles Egaux. Par exemple, la premiEre unitE de commande de soupape (12) alimente les soupapes d'injection de carburant qui sont installEes sur le premier, quatriEme, sixiEme et septiEme cylindre, et la deuxiEme unitE de commande de soupape (13) alimente les soupapes d'injection de carburant qui sont installEes sur le second, troisiEme, cinquiEme et huitiEme cylindre.
