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).

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.

Fuel injection nozzle

Anatoru Abudenko, +8 more
TL;DR: In this article, an extension spiral coil spring wound spirally is used to hold a pressure in a fuel distribution line by a nozzle by overlapping one end of the coil of the spring with an end part of a tubular member.

Fuel injection apparatus and control method thereof

Toshiharu Nogi, +3 more
TL;DR: In this article, a fuel-air mixture is supplied with stability to the neighboring area of an ignition plug without any effect on deflection of fuel spray due to the air flow (swirl/tumble) in a combustion chamber, leading to the prevention of occurrence of smoke.

Perforated body and valve with a perforated body

Guenther Dipl Ing Findler, +2 more
TL;DR: The perforated body and the valve are particularly suitable for injection systems of spark-ignition internal combustion engines as discussed by the authors, and they have been shown to be suitable for the injection of fuel or of a fuel/gas mixture.

Liquid control valve

Roger Potschin, +1 more
TL;DR: In this article, a valve member forms a movable wall of a pressure chamber which is restricted from an actuator piston of a piezo-actuator, where the operating piston can be adjusted against the force of the pressure spring.

Fuel injection valve

Jonas Stephan
TL;DR: In this article, a double spring type holder is used to provide a fuel injection valve with a simple structure and a low cost by connecting a buffer volume functioning against the opening stroke of the valve member of the fuel injector to a fuel inflow section via a restriction.
