Fuel injection valve for IC engines produces fuel jet pattern regulated dependent upon engine type or output

摘要

The injection nozzle has a large number of nozzle opening groups (60) producing a fuel jet pattern, the shape of which is regulated dependent upon the internal diameters of a specific nozzle opening (601) and the opening (602) next to it, the distance between the opening, and the directions of the fuel injected by the two openings. The nozzle openings are located in circumferential direction around the nozzle body (11).
