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).read more

Spray pattern control with non-angled orifices formed on a generally planar metering disc and reoriented on subsequently dimpled fuel injection metering disc
TL;DR: In this paper, the authors proposed a method of controlling spray targeting of a fuel injector, where the metering orifices can be located on a first virtual circle greater than a second virtual circle as defined by a projection of a sealing surface converging at a virtual apex projected on the meeting disc.

Injector-igniter with thermochemical regeneration
Abstract: A fuel injection system comprising an injector-igniter and a fuel tank in fluid communication with the injector-igniter. The injector igniter includes an injector housing and a valve assembly. The valve assembly includes a valve and a valve seat electrode located within the injector housing. The valve seat electrode forms an annular spark gap between the electrode and an electrode portion of the injector housing. An actuator, such as a piezoelectric actuator, is disposed in the housing and connected to the valve. In some embodiments, the system further comprises a thermochemical reactor operatively coupled to the injector-igniter to provide a supplemental supply of hydrogen for combustion enhancement. In other embodiments, a hydraulic stroke amplifier is disposed between the actuator and valve.

TL;DR: In this article, a tapered valve seat surface (16 or 16a) located in an end-cup (20 or 20a) of the fuel injection nozzle body (10), in which at least one spray orifice (22) is provided.
Patent
Fuel-injection device for internal-combustion engines
TL;DR: In this paper, a solenoid valve is used to detect the stroke moment of the needle needle as a precise signal of the commencement and termination of the injection and transmits it to the control device, where this actual value is compared with a desired value from performance characteristics and, if necessary, results in a correction of the controlling of the valve.
Patent
Fuel injection system
TL;DR: In this paper, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from a damping chamber via damping throttle in an injection event reaches the fillingpath of the pressure booster pressure chamber via the damped path.
