Abstract
Official abstract text for this publication.
A dual fuel injection valve includes a primary fuel treatment space and a secondary fuel treatment space formed extending the fuel valve block and the hybrid nozzle block in the longitudinal direction and side by side with each other. The primary fuel treatment space includes a primary cylinder passage, a primary fuel passage and a primary nozzle hole. The secondary fuel treatment space includes a secondary cylinder passage formed separately form the primary cylinder passage, a secondary fuel passage formed separately form the primary fuel passage hole, a secondary nozzle hole. The dual fuel injection valve further includes a first chamber formed in a lower portion of the secondary cylinder passage, a second chamber disposed between the first chamber and the secondary nozzle hole and formed to surround the secondary cylinder passage, and a primary fuel movement hole connecting the primary cylinder passage and the second chamber.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dual fuel injection valve comprising: a fuel valve block; a hybrid nozzle block coupled to an end of the fuel valve block; a primary cylinder passage formed by the fuel valve block and the hybrid nozzle block such that a first portion of the primary cylinder passage extends through the fuel valve block and a second portion of the primary cylinder passage extends through the hybrid nozzle block; a primary fuel passage formed to introduce a prima…
