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).

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.

Combustion control system for internal combustion engines

Henry C. Linder
TL;DR: A combustion control system for internal combustion engines which includes a novel spark plug having a precombustion chamber in which a butane/air mixture injected through the plug is ignited in order to initiate and manage combustion wave propagation within the engine cylinder is described in this paper.

Pre-adjustment method and dynamic correction of piezoelectric actuators e.g. for fuel-injection valve drive in motor vehicles

Nils Kroemer
TL;DR: In this paper, a method of adjusting and correcting or compensating electric piezo-actuators from a stack of piezos-elements placed one on the other, in which an idling stroke (ho) exists between the piezo actuator and an actuating element (valve stem 3) with the drive voltage (U1) not applied, is presented.

Fuel injection valve

Furuya Yuji, +2 more
TL;DR: In this paper, a valve element is axially movably received in the body and a valve part is fully lifted from a position where a valve portion formed on the lower end of the valve element sits on the valve seat to a position when an upper end portion is brought into abutment with a stopper of the body.
