Fuel-injection valve

Guenter Dantes, +1 more
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

Ryuji Aoki, +3 more
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

Yoshio Okamoto, +8 more
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

Akinori Harata, +1 more
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

Mauro Grandi, +2 more
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

Tsuchiya Masahiro, +9 more
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.

Air-assist fuel injection system

George Saikalis, +2 more
TL;DR: An air-assist fuel injection system controls the supply of compressed air to the fuel injectors according to the operating status of an internal combustion engine as mentioned in this paper, where the air is supplied as a pulsating flow consisting of air pulses coincident with the injected fuel pulses.

Fuel injection device for internal combustion engines

Ganser Marco Alfredo
TL;DR: The opening and closing movement of a injector valve member (32) which closes and temporarily opens discharge orifices communicating with the combustion chamber of an internal combustion engine, for example a diesel engine, is controlled by the fuel pressure in a control chamber (42) arranged at one end of the injector member.
