摘要： A fuel injector for an internal combustion engine is disclosed. In the fuel injector, an opening on the outer side of the injection hole has a width generally larger than a height thereof. The width of the injection hole is gradually narrowed inward so that the fuel is injected at a predetermined angle in the direction of width. The height of the injection hole is nearly uniform in the direction of injecting the fuel within the predetermined angle in the direction of width. A height at both ends of the opening on the outer side of the injection hole is larger than the height at the central portion thereof.

摘要： A fuel injection apparatus of an internal combustion engine includes a valve body movably disposed for back and forth movement in a fuel passage to open and close a fuel injection hole of the fuel injection apparatus. An armature is attached to the valve body. A valve-opening solenoid coil drives the armature in a valve-opening direction. A valve-closing solenoid coil drives the armature in a valve-closing direction. A controller that sets an overlap time, which is a time by which starting of electrifying of the valve-closing solenoid coil precedes stopping of electrifying of the valve-opening solenoid coil, controls the solenoid coils in accordance with a fuel pressure supplied to the fuel injection apparatus such that a valve-closing force on the valve body does not exceed an open valve holding force on the valve body prior to the time when stopping of the electrifying of the valve-opening solenoid coil occurs.

摘要： A fuel injection valve, for an engine, comprising a nozzle body having a plurality of nozzle holes and a needle valve reciprocated in the nozzle body for controlling the inflow of the fuel into the nozzle holes is disclosed. The fuel is rendered to flow into the nozzle holes from a direction along the inner wall surface of the nozzle body around each of the nozzle holes in a first inflow mode, and from a direction substantially perpendicular to the inner wall surface of the nozzle body in a second inflow mode. The first inflow mode and the second inflow mode can be selectively switched to each other. The fuel is rendered to flow into the nozzle holes in the first inflow mode before the lapse of a predetermined time after the engine is started, and in the first or second mode as required after the lapse of the predetermined time.

摘要： A fuel jet adjusting plate has first nozzle holes arranged along a first circle coaxial with a central axis of a valve body and second nozzle holes arranged along a second circle coaxial with the central axis and having a diameter larger than that of the first circle. Each hole axis of the second nozzle holes forms an acute angle with a reference plane perpendicular to the central axis of the valve body smaller than that formed by each hole axis of the first nozzle holes with the reference plane. Hence, fuel sprays injected through the first nozzle holes can be directed away from fuel sprays injected through the second nozzle holes. As a result, the fuel sprays injected through the first nozzle holes do not interfere with the fuel sprays injected through the second nozzle holes, which makes it possible to suitably atomize injected fuel.
摘要翻译：燃料喷射调节板具有沿着与阀体的中心轴同轴的第一圆周布置的第一喷嘴孔和沿着与中心轴线同轴的第二圆周布置并且具有比第一圆的直径大的直径的第二喷嘴孔。第二喷嘴孔的每个孔轴与垂直于阀体的中心轴线的参考平面形成锐角，其小于由具有参考平面的第一喷嘴孔的每个孔轴形成的参考平面。因此，通过第一喷嘴孔喷射的燃料喷射可以被引导离开通过第二喷嘴孔注入的燃料喷射。结果，通过第一喷嘴孔喷射的燃料喷射不会干扰通过第二喷嘴孔喷射的燃料喷雾，这使得可以适当地雾化喷射的燃料。

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.
