摘要： A fuel injection structure for an internal combustion engine includes a straight intake port defining passage formed in an intake passage of the engine and a fuel injection valve disposed within a passage-defining wall which defines the straight intake port defining passage therein. The fuel injection valve is arranged inside the intake passage in parallel with a passage axis of the straight intake port defining passage in an elevational view of the engine. The fuel is injected from the fuel injection valve and flows in parallel with the intake air flow. Due to the parallel flow of the fuel and the intake air, the injected fuel does not tend to adhere to the wall surface of the intake port defining passage. This parallel flow is not affected by a change in the speed of the intake air flow.

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： 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： 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： A valve seat portion has fuel flow passages arranged between guide portions at predetermined intervals along an outer circumference of a valve body. In addition, a fuel jet adjusting plate has nozzle holes arranged along a circle coaxial with the outer circumference of the valve body, the nozzle holes corresponding to the guide portions. Therefore, even if the valve body rotates circumferentially relative to the valve seat portion, no alteration in the pressure applied to fuel flowing through the nozzle holes occurs. By suitably setting relative locations between the respective nozzle holes and the guide portions and the numbers thereof, the pressure applied to fuel injected from the respective nozzle holes is adjusted, whereby the fuel injected from the respective nozzle holes is optimally atomized.
