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).

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.

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 system comprising an injection valve for a self-igniting internal combustion engine

Kapus Paul Dr
TL;DR: In this paper, the magnetic force of a solenoid was used to create simplified rate shaping for a self-igniting internal combustion engine with direct fuel injection, in particular for liquefied gas fuels, and which is configured as a pintle-type nozzle opening against the force of at least one spring.

Low mass, through flow armature

TL;DR: In this article, the impact minimization means (30) are provided to minimize the effect of such impact forces, and the impact-minimization means comprises on the armature (20) multi-dimensional fluid passages through the armatures that minimizes the effect in comparison to the impact forces in the absence of the multidimensional fluid passages, where the one side of the Armature causes impact forces to be exerted axially on the stator during the opening and closing of the flow path.
