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

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.
