Nozzle body for a fuel injection nozzle with optimized injection hole duct geometry

摘要

In a nozzle body, a degree of rounding of edges of an entry region of an injection hole duct in the nozzle body is dependent on a distribution of a fuel stream around the entry region. The edges being more rounded, the greater the fuel stream at the respective edge portion is. The entry region of the injection hole duct has, in this case, preferably the form of an ellipse.
