Abstract
Kraftstoffversorgungsanlage für eine mit Schweröl betriebene Brennkraftmaschine mit mindestens einem Hochdruckspeicher, von dem der erwärmte Kraftstoff über Ventile je einem Zylinder der Brennkraftmaschine zugeführt wird, wobei der Hochdruckspeicher einen inneren, den unter Druck stehenden Kraftstoff aufnehmenden, rohrförmig ausgebildeten Druckkörper (1) sowie einen den Druckkörper unter Bildung eines Hohlraums (5) umgreifenden Mantel (4) aufweist, dadurch gekennzeichnet, dass wenigstens ein Teil des Hohlraums (5) mit einem Fluid beaufschlagbar ist, dessen Temperatur mindestens annähernd der Temperatur des einzuspritzenden Kraftstoffs entspricht, wobei der Druckkörper (1) beiderseits unter Einschaltung einer Dichtung (7) durch je einen Deckel (2, 3) geschlossen ist, innerhalb des Hohlraumes (5) mit geringem Abstand von jeder Deckeldichtung (7) eine weitere Dichtung (8) angeordnet ist, die einen mit einer Abflussleitung (10) versehenen Leckkraftstoffsammelraum (9) von dem restlichen, mit dem Fluid beaufschlagbaren Hohlraum (5) trennt.Fuel supply system for an engine operated with heavy oil with at least one high-pressure accumulator, from which the heated fuel is supplied via valves per a cylinder of the internal combustion engine, wherein the high-pressure accumulator an inner, the pressurized fuel receiving, tubular pressure body formed (1) and a pressure body Having a cavity (5) embracing jacket (4), characterized in that at least a portion of the cavity (5) is acted upon by a fluid whose temperature at least approximately corresponds to the temperature of the fuel to be injected, wherein the pressure body (1) on both sides with the involvement of a seal (7) by a respective cover (2, 3) is closed, within the cavity (5) at a small distance from each lid seal (7), a further seal (8) is arranged, which is provided with a drain line (10 ) Leakage fuel collecting space (9) of the rest union, acted upon by the fluid cavity (5) separates.
Description
Die Erfindung betrifft eine Kraftstoffversorgungsanlage für eine mit Schweröl betriebene Brennkraftmaschine mit mindestens einem Hochdruckspeicher, von dem der erwärmte Kraftstoff über Ventile je einem Zylinder der Brennkraftmaschine zugeführt wird, wobei der Hochdruckspeicher einen inneren, den unter Druck stehenden Kraftstoff aufnehmenden rohrförmig ausgebildeten Druckkörper sowie einen den Druckkörper unter Bildung eines Hohlraumes umgreifenden Mantel aufweist.The The invention relates to a fuel supply system for a with heavy oil operated internal combustion engine with at least one high-pressure accumulator, of which the heated one Fuel over Valves are each supplied to a cylinder of the internal combustion engine, wherein the high-pressure accumulator an inner, the pressurized Fuel receiving tubular trained pressure body as well as the pressure body Having a cavity enclosing shell.

Der Erfindung liegt die Aufgabe zugrunde, Wärmeverluste des im Druckkörper befindlichen Kraftstoffs zu vermindern.Of the Invention is based on the object, heat losses of the fuel located in the pressure body to diminish.
Erfindungsgemäß wird dies dadurch erreicht, dass mindestens ein Teil des Hohlraumes mit einem Fluid beaufschlagbar ist, dessen Temperatur mindestens annähernd der Temperatur des einzuspritzenden Kraftstoffs entspricht. Durch diese Maßnahme wird zumindest ein Wämeübergang durch die Wandung des Druckkörpers nach außen vermieden. Durch den Einsatz eines Fluids, dessen Temperatur die Temperatur des Kraftstoffs übersteigt, kann dessen Fließfähigkeit gesteigert werden.According to the invention this is achieved in that at least a portion of the cavity with a fluid can be acted upon, whose temperature is at least approximately Temperature of the fuel to be injected corresponds. Through this Measure becomes at least one heat transition through the wall of the pressure hull outward avoided. By using a fluid whose temperature is the Temperature of the fuel exceeds can its fluidity be increased.
Desweiteren ist bei einer Kraftstoffversorgungsanlage, bei der der Druckkörper beiderseits unter Einschaltung einer Dichtung durch je einen Deckel geschlossen ist, innerhalb des Hohlraumes mit geringem Abstand von jeder Deckeldichtung eine weitere Dichtung angeordnet, die einen mit einer Abflussleitung versehenen Leckkraftstoffsammelraum von dem restlichen, mit dem Fluid beaufschlagbaren Hohlraum trennt.Furthermore is in a fuel supply system, in which the pressure body on both sides closed with a seal by a cover is, within the cavity with a small distance from each lid seal another seal arranged, the one with a drain pipe Provided leak fuel collecting space from the remaining, with the Fluid loadable cavity separates.
Vorzugsweise ist das Fluid unter geringem Druck stehender erwärmter Kraftstoff. Da dieser ohnehin zur Verfügung steht, sind lediglich einfache Rohrleitungen zu Realisierung der Erfindung erforderlich.Preferably the fluid is low pressure heated fuel. Because of this available anyway stands, are only simple piping to the realization of Invention required.
Nach einer anderen Ausgestaltung der Erfindung ist ein gesonderter Kreislauf für das Fluid, beispielsweise Öl oder Dampf, vorgesehen. In diesem Fall besteht die Möglichkeit der zusätzlichen Aufheizung des im Druckkörper befindlichen Kraftstoffs.To Another embodiment of the invention is a separate circuit for the Fluid, for example oil or steam, provided. In this case, there is the possibility the additional Heating the in the pressure hull located fuel.
Weitere Merkmale und Vorteile ergeben sich aus den zusätzlichen Unteransprüchen und einer Beschreibung eines Ausführungsbeispieles der Erfindung anhand der Zeichnung. Auf dieser zeigt:Further Features and advantages emerge from the additional subclaims and a description of an embodiment the invention with reference to the drawing. On this shows:
