摘要： A fuel injection nozzle is configured and dimensional with a flat flow passage just above the outlet orifice(s). When the abutting portion of a needle valve moves away from the valve seat, fuel flows are directed uniformly toward the orifice from around its periphery so as to collide with each other just above each orifice inlet. Atomized fuel is then injected to the engine from the orifice. The internal energy of the fuel flows can more effectively be utilized in the collisions to more finely atomize the fuel and to maintain the ability to provide a highly direction output injection spray.

摘要： The present invention makes it possible to obtain good characteristics of forming sprays of fuel jetted through a plurality of injection ports of a fuel injection valve with respect to separation of sprays in different directions, atomization, jetting angles and penetrating force.Fuel jetted through the injection ports of the fuel injection valve is jetted in separate jets from a plurality of fuel flow separating holes of a sleeve nozzle. On the other hand, band-like assist air flows are jetted in a two-dimensional manner from slit-like air holes opened on the opposite sides of the fuel flow separating holes to impinge obliquely against the jetted fuel. Atomization of fuel jetted through the plurality of fuel flow separating holes is thereby promoted and fuel sprays are accurately separated and supplied independently in two directions toward two intake valves while the directions of jets from the injection ports of the fuel injection valve are maintained, thus injecting and supplying fuel. As a result, an amount of fuel impinging directly against walls which separates and forms two intake ports is reduced and an amount of atomized sprayed fuel directly entering a combustion chamber from the intake ports is therefore increased, thereby improving combustion characteristics.
摘要翻译：本发明可以获得通过燃料喷射阀的多个注射口喷射的燃料的喷雾的良好特性，其特征在于相对于不同方向上的喷雾分离，雾化，喷射角度和穿透力。通过燃料喷射阀的喷射口喷射的燃料从与套管喷嘴的多个燃料流分离孔分离的射流喷射。另一方面，带状辅助空气流从在燃料流分离孔的相对侧开口的狭缝状气孔以二维方式喷射，倾斜地抵靠喷射燃料。从而促进通过多个燃料流分离孔喷射的燃料的雾化，并且燃料喷射被精确地分离并且在朝向两个进气门的两个方向上独立供应，同时保持来自燃料喷射阀的喷射口的喷射方向，从而注入并供应燃料。结果，直接撞击分隔并形成两个进气口的壁的燃料量减少，因此从进气口直接进入燃烧室的雾化喷雾燃料的量增加，从而提高燃烧特性。

摘要： A nozzle holder includes a support portion, which supports a downstream end surface of a planar wall of an injection hole plate. The injection hole plate provided with injection holes is welded to one of the valve body and the nozzle holder. The planar wall may be curved and may be thus convex in an upstream direction toward a downstream end opening such that the planar wall is urged against a peripheral edge of the downstream end opening of the valve body. The planar wall may include a reinforcing rib located radially outward of the injection hole.

摘要： There is provided a fuel injection valve in which nozzle holes are formed on a metering plate and fuel flowing on a face of the metering plate on the upstream side is injected outside of a face of the metering plate on the downstream side through the nozzle holes. The fuel injection valve includes a vortex flow generator means for changing a flow of fuel passing in each nozzle hole into a vortex flow, wherein the vortex flow generator means is provided on the upstream side of the metering plate. The vortex flow means is a vortex flow generator groove provided on an upper face of the metering plate and connected with a wall face of an entrance of the nozzle hole, and a main stream of fuel flowing in the groove is directed to a position shifted from the center of the nozzle hole. Alternatively, the vortex flow means is a protrusion formed on an upper face of the metering plate. A flow of fuel is changed into a vortex flow in the nozzle hole and injected from the nozzle hole. Therefore, fuel can be excellently atomized and diffused as a megaphone-shape without being formed into a liquid column spray.

摘要： Twelve injection holes formed on an injection hole member are separated into two groups, each one of the two groups has six injection holes for forming a spray. Each injection hole is formed such that its injected fuel flow path center diverges from an injection center axis as fuel advances in an injection direction. Respective injected fuel flow path centers diverge from each other as fuel advances in the injection direction. Accordingly, fuel injected from the injection holes do not collide each other and form sprays. Thus, the spray is uniformly atomized, and a deviation of the spray direction is prevented.
摘要翻译：在喷孔构件上形成的12个喷射孔分成两组，两组中的每一个具有六个用于形成喷雾的喷射孔。每个喷射孔形成为使得当喷射燃料沿着喷射方向前进时，其喷射的燃料流动路径中心从喷射中心轴线分叉。当燃料在喷射方向上前进时，各喷射燃料流路中心彼此分开。因此，从喷射孔喷出的燃料不会相互碰撞而形成喷雾。因此，喷雾均匀雾化，并且防止了喷射方向的偏离。
