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

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.
