Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zum Einspritzen von Wasser in einen Brennraum oder in einen Ansaugtrakt eines Verbrennungsmotors, umfassend ein Rail (1) sowie mindestens ein an das Rail (1) angeschlossenes Einspritzventil (2), wobei der Anschluss über eine Railtasse (3) realisiert ist, die das Einspritzventil (2) an seinem railseitigen Ende umgibt. Erfindungsgemäß weist das Einspritzventil (2) einen zum Rail (1) hin offenen Zulaufkanal (4) auf, in dem zur Reduzierung des Zulaufquerschnitts ein Einsatz (5) zumindest abschnittsweise aufgenommen ist.
(EN)
The invention relates to a device for injecting water into a combustion chamber or into an intake tract of an internal combustion engine, comprising a rail (1) and at least one injection valve (2) connected to the rail (1), the connection being produced by means of a rail cup (3), which surrounds the injection valve (2) at the rail-side end of the injection valve. According to the invention, the injection valve (2) has a feed channel (4) open toward the rail (1), in which feed channel at least some portions of an insert (5) are received in order to reduce the feed cross-section.
(FR)
L'invention concerne un dispositif d'injection d'eau dans une chambre de combustion ou dans un conduit d'aspiration d'un moteur à combustion interne, comprenant un rail (1) ainsi qu'au moins un injecteur de carburant (2) raccordé au rail (1), le raccordement étant réalisé à l'aide d'une tasse de rail (3), qui entoure l'injecteur de carburant (2) à son extrémité côté rail. Selon l'invention, l'injecteur de carburant (2) comporte un canal d'amenée (4) ouvert vers le rail (1), dans lequel, pour réduire la section transversale d'amenée, un insert (5) est logé, au moins par sections.
