Die hier vorliegende Erfindung betrifft eine Common-Rail Kraftstoffversorgungsanlage einer Brennkraftmaschine, insbesondere einer mit Schweröl betriebenen Schiffsdieselbrennkraftmaschine. Common-Rail Kraftstoffversorgungsanlagen verfügen über einen Niederdruckbereich sowie einen Hochdruckbereich. Der Hochdruckbereich einer Common-Rail Kraftstoffversorgungsanlage umfasst eine zumindest eine Hochdruckpumpe aufweisende Pumpeinrichtung und ein zumindest eine Speichereinheit aufweisendes Druckspeichersystem, wobei die Pumpeinrichtung Kraftstoff aus dem Niederdruckbereich in den Hochdruckbereich fördert und mit dem Druckspeichersystem über mindestens eine Hochdruckkraftstoffleitung verbunden ist. Das Druckspeichersystem sowie die oder jede das Druckspeichersystem mit der Pumpeinrichtung verbindende Hochdruckkraftstoffleitung stehen permanent unter einem hohen Arbeitsdruck. Ausgehend vom Druckspeichersystem ist der Kraftstoff über Injektoren in Zylinder einspritzbar, wobei jeder Injektor mit dem Druckspeichersystem über mindestens eine Hochdruckkraftstoffleitung verbunden ist, die abhängig vom Einspritztakt der Brennkraftmaschine zeitweise unter Hochdruck steht.The present invention relates to a common rail fuel supply system of an internal combustion engine, in particular a marine diesel engine operated with heavy oil. Common-rail fuel supply systems have a low-pressure range and a high-pressure range. The high-pressure region of a common-rail fuel supply system comprises a pump device having at least one high-pressure pump and an accumulator system having at least one storage unit, wherein the pump device conveys fuel from the low-pressure region into the high-pressure region and is connected to the accumulator system via at least one high-pressure fuel line. The accumulator system and the or each high pressure fuel line connecting the accumulator system to the pump means are permanently under a high working pressure. Starting from the pressure accumulator system, the fuel can be injected via injectors into cylinders, each injector being connected to the accumulator system via at least one high-pressure fuel line, which depends on the inlet injection cycle of the internal combustion engine is temporarily under high pressure.
