Fuel-injection valve

TLDR
In this article, a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine is described, and a slit-type flow outlet is formed between the slit-forming element and a front face of the valve seat body.
Abstract
The invention relates to a fuel-injection valve, in particular a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine. Said valve is characterised in that an outlet opening (23) is provided downstream of the valve seat (20), the downstream end of said opening having a slit-forming element (30) that to a great extent closes the outlet opening (23). A slit-type flow outlet (35), through which a fuel spray can be discharged in a fan-type jet, is formed between the slit-forming element (30) and a front face (34) of the valve seat body (16).

Fuel Injection Valve

TL;DR: In this article, a fuel injection valve is provided that includes a valve seat member (3) having a conical valve seat (8), and a valve hole (7 ) formed through a central part of the valve seat, a valve body (18) working in cooperation with the valve, and an injector plate (10) joined to the valve member and having a plurality of fuel injection holes (11 ) radially outwardly displaced from the valve hole.

Electromagnetic fuel injection valve

TL;DR: In this article, an injector used for an internal combustion engine is described, in which a favorable magnetic attraction force is obtained to reduce a controllable minimum injection amount of a fuel injection amount.
Patent

Fluid injection nozzle

TL;DR: A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed as mentioned in this paper, and fuel flows along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the throughhole.

Valve assembly for an injection valve and injection valve

TL;DR: In this article, a valve assembly for an injection valve is described, where the valve body is axially movable relative to the valve needle and a permanent magnet is arranged in the cavity at a position adjacent to the position of the armature when the needle is in its closing position.
Patent

Fuel Injection Valve

TL;DR: In this article, the phase angle of force applied to the primary oscillation system by the secondary oscillator is also staggered from that of the force applied by the SOS, which in turn makes it possible to achieve very accurate fuel-injection control.

Fuel injection valve for IC engines has pressure-reducing throttle between high-pressure fuel in fuel chamber/line and lower pressure fuel in valve needle actuator area

TL;DR: In this paper, the throttle is located between a valve spring (4) next to the fuel chamber and an actuator spring (15), where the fuel is a spiral chamber with tangential flow channels.
Patent

Fuel injection valve for internal combustion engine, preferably for high jet speeds, has spray channels with cross-sections that expand after jet hole

TL;DR: In this paper, an axially guided valve element was opened hydraulically against a closing force with a conical sealing surface that interacts with conical valve seat surface and hydraulic connections from the pressure chamber to spray channels.

Fuel injection valve for internal combustion engine, with actuator acting via needle carrier on valve needle

TL;DR: In this paper, the actuator acts on the valve needle via a shell-shaped needle carrier separated from the valve and movable axially relative to it, and the closed body is returned by a spring to the closed position.
Patent

Fuel injection valve consists of an actuator located in a housing connected on the side of a valve needle to a valve body

TL;DR: A fuel injection valve as mentioned in this paper consists of an actuator located in a housing (13) that is connected on the side of a valve needle to a valve body, using a positive fit.
