Abstract

Es wird ein Kraftstoffzufuhrzusammenbau (10) mit einem Motorblock (12) mit mehreren sich kreuzenden Kraftstoffzufuhröffnungen (30) und Kraftstoffeinspritzöffnungen (16) und einem gemeinsamen Rückflusskanal (36), der die Kraftstoffzufuhröffnungen (30) mit einem Kraftstoffreservoir verbindet, und einer Mehrzahl von in den Kraftstoffeinspritzöffnungen (16) angeordneten Kraftstoffeinspritzdüsen (18), welche einen Rückflussausgang (24) aufweisen, welcher überschüssigen Kraftstoff aus der Kraftstoffeinspritzdüse (18) leitet, sowie einer Mehrzahl von in den Kraftstoffzufuhröffnungen (30) angeordneten Kraftstoffzufuhrelementen (40), welche jeweils einen Kraftstoffzufuhrkanal (50) aufweisen, welcher unter Druck stehenden Kraftstoff zu einer zugeordneten Kraftstoffeinspritzdüse (18) leitet, vorgeschlagen. Um den Aufbau des Kraftstoffzufuhrzusammenbaus zu vereinfachen, bilden eine Außenfläche jedes Kraftstoffzufuhrelements (40) und eine Innenfläche jeder Kraftstoffzufuhröffnung (30) eine Rückflusskammer (54), welche mit einem zugehörigen Rückflussausgang und mit dem gemeinsamen Rückflusskanal (36) in Verbindung steht.
