摘要： A fuel injector comprising a nozzle body, a first outlet opening having an axis, a second outlet opening having an axis, and means for controlling fuel delivery through the first and second outlet openings. The axes of the first and second outlet openings are arranged so as to intersect one another downstream of the outlet openings such that, when fuel is delivered through both the first and second outlet openings, a combined spray formation is formed which is substantially equivalent to a single spray formation having been delivered from a single opening.

摘要： A fuel injector for delivering fuel to a combustion chamber having a chamber ceiling, the fuel injector having a primary axis and able to control fuel delivery through a first outlet opening or together through both the first outlet opening and a second outlet opening. The first and second outlet openings are oriented such that, in use, when fuel delivery is permitted through only the first outlet opening, a first spray formation reaches a first target distance below the chamber ceiling at a radial distance from the primary axis. When fuel delivery is permitted through both openings together, respective first and second spray formations merge externally of the injector so as to give rise to a combined spray formation reaching second target distance below the chamber ceiling at the radial distance from the primary nozzle axis, wherein the second target distance is larger than the first target distance.
摘要翻译：一种用于将燃料输送到具有室顶部的燃烧室的燃料喷射器，所述燃料喷射器具有主轴线并且能够控制通过第一出口开口的燃料输送或者通过第一出口开口和第二出口开口一起。第一和第二出口开口被定向成使得在使用中，当仅通过第一出口开口允许燃料输送时，第一喷射结构在与主轴线径向距离处达到室顶部下方的第一目标距离。当允许通过两个开口一起燃料输送时，相应的第一和第二喷射结构在喷射器的外部合并，以便在距离主喷嘴轴线的径向距离处产生达到腔室顶部下方第二目标距离的组合喷射形成，其中第二目标距离大于第一目标距离。

摘要： A fuel injector mountable with respect to a combustion chamber for delivering fuel thereto, the combustion chamber comprising a chamber ceiling and a chamber wall, the fuel injector comprising a nozzle body having a primary nozzle axis; a first outlet opening having a first axis; a second outlet opening having a second axis; and means for controlling fuel delivery through the first and second outlet openings. The means for controlling fuel delivery comprises an inner valve needle and an outer valve needle, and is arranged to permit fuel delivery from only the first outlet opening, or through both the first and second outlet openings together. The first and second outlet openings are oriented such that, in use, when fuel delivery is permitted through only said first outlet opening, a first spray formation is injected along the first axis, the first spray formation reaching a first target distance below said chamber ceiling at a radial distance from the primary nozzle axis. When fuel delivery is permitted through both openings together, respective first and second spray formations are injected along the respective first and second axes to merge externally of the injector so as to give rise to a combined spray formation having a third axis. The combined spray formation reaches a second target distance below said chamber ceiling at said radial distance from the primary nozzle axis, and is substantially equivalent to a spray formation delivered as if from a single outlet opening having a diameter greater than that of the first outlet opening. The first target distance is less than the second target distance.
