Description

Die Erfindung betrifft eine Hubkolbenbrennkraftmaschine, die für Schwerölbetrieb geeignet ist, mit einer Kraftstoff unter hohem Druck führenden Kraftstoffspeicherleitung zur Versorgung von Einspritzventilen.The invention relates to a reciprocating internal combustion engine, which is suitable for heavy oil operation, with a fuel under high pressure leading fuel storage line for the supply of injectors.

Aus der JP 8-338339 A oder der DE 199 45 436 C1 ist beispielsweise bereits eine Hubkolbenbrennkraftmaschine bekannt, die für Schweröl geeignet ist, mit einer Kraftstoff unter hohem Druck führenden Kraftstoffspeicherleitung zur Versorgung von Einspritzventilen, in dieser ein elektrisches Heizelement zentral angeordnet ist.From the JP 8-338339 A or the DE 199 45 436 C1 For example, a reciprocating internal combustion engine is already known, which is suitable for heavy oil, with a fuel at high pressure fuel storage line leading to the supply of injectors, in which an electric heating element is arranged centrally.

Neben einem zentralangeordneten elektrischen Heizelement sind noch auch Wärmetauscher mit einem zentralen Wärmetauscherrohr in einer Kraftstoffspeicherleitung beispielsweise aus der DE 197 05 631 A1 oder der US 6,269,804 B1 bekannt. Aus der DE 35 162 53 A1 ist zudem bekannt, Heizdampf als Wärmeträgermedium bei großen schwerölbetriebenen Brennkraftmaschinenanlagen zu verwenden.In addition to a centrally arranged electrical heating element are still heat exchangers with a central heat exchanger tube in a fuel storage line, for example, from DE 197 05 631 A1 or the US 6,269,804 B1 known. From the DE 35 162 53 A1 is also known to use heating steam as a heat transfer medium in large oil-powered engine systems.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen, platzsparenden Mitteln die Verfügbarkeit der Hubkolbenbrennkraftmaschine zu erhöhen.The invention has for its object to increase the availability of reciprocating internal combustion engine with simple, space-saving means.

Diese Aufgabe wird dadurch gelöst, dass zentral in der Kraftstoffspeicherleitung ein Heizelement in Form eines mit Heißdampf beaufschlagten Rohres angeordnet ist, dass an beiden Enden der Kraftstoffspeicherleitung je ein Abschlussstück angeordnet ist, das den Innenraum der Kraftstoffspeicherleitung druckdicht verschließt, wobei jedes Abschlussstück eine Bohrung aufweist, an diese Rohrleitungen zur Aufrechterhaltung einer Zirkulation des Heizdampfes angeschlossen sind. Bei Anwendung der Erfindung kann an den Einspritzventilen stets Kraftstoff mit der erforderlichen Temperatur und dadurch der erforderlichen Viskosität anstehen. Die Maschine kann also auch nach einer Stillstandsphase problemlos angefahren werden. Auch im Betrieb wird die Einhaltung der zu fordernden Viskosität des Kraftstoffes begünstigt.This object is achieved in that centrally in the fuel storage line, a heating element is arranged in the form of a superheated steam pipe, that at each end of the fuel storage line a respective end piece is arranged, which pressure-tightly closes the interior of the fuel storage line, each end piece has a bore, connected to these pipelines to maintain a circulation of the heating steam. When using the invention can always be present at the injection valves fuel at the required temperature and thus the required viscosity. The machine can therefore be approached easily after a standstill phase. Even in operation, compliance with the required viscosity of the fuel is favored.

Vorteilhaft ist die Kraftstoffspeicherleitung unter Einschluss eines Luftspaltes ummantelt. Hierdurch kann der Wärmeverlust minimiert werden.Advantageously, the fuel storage line is enclosed with the inclusion of an air gap. As a result, the heat loss can be minimized.

Weitere Merkmale und Vorteile ergeben sich aus den zusätzlichen Unteransprüchen und einer Beschreibung eines Ausführungsbeispieles anhand der Zeichnung. Diese zeigt einen Teil einer Kraftstoffspeicherleitung mit den daran anschließenden Teilen im Schnitt.Further features and advantages will become apparent from the additional dependent claims and a description of an embodiment with reference to the drawing. This shows a part of a fuel storage line with the adjoining parts in section.

Auf der Zeichnung ist die rohrförmig ausgeführte Kraftstoffspeicherleitung mit 1 bezeichnet. In den Innenraum 2, der dem unter hohen Druck stehenden Kraftstoff aufnimmt, ist ein Heizelement 3 eingebracht. Das Heizelement ist im dargestellten Ausführungsbeispiel als mit Heißdampf beaufschlagtes Rohr ausgebildet. An den beiden Enden der Kraftstoffspeicherleitung 1 ist je ein Abschlussstück 4 angeordnet, das den Innenraum 2 druckdicht verschließt. Auf der Zeichnung ist nur das eine Abschlussstück 4 dargestellt. Jedes Abschlussstück 4 weist eine Bohrung 5 auf, an die nicht dargestellte Rohrleitungen zur Aufrechterhaltung einer Zirkulation des Heißdampfes angeschlossen sind. Das Heizelement 3 und die Bohrung 5 sind dabei gegenüber dem Innenraum 2 druckdicht ausgeführt. Die Kraftstoffspeicherleitung 1 steht in an sich bekannter Weise über Bohrungen in Anschlussstücken 6 und je eine anschließende Rohrleitung 7 mit je einem Einspritzventil 8 in Verbindung. Zwischen zwei Anschlussstücken 6 bzw. einem Anschlussstück 6 und einem Abschlussstück 4 ist um die Kraftstoffspeicherleitung 1 unter Einschluss eines Luftspaltes jeweils ein Mantelrohrstück 9 angeordnet.In the drawing, the tubular running fuel storage line with 1 designated. In the interior 2 which receives the fuel under high pressure is a heating element 3 brought in. The heating element is formed in the illustrated embodiment as acted upon with superheated steam pipe. At the two ends of the fuel storage line 1 is ever a final piece 4 arranged that the interior 2 pressure tight closes. On the drawing, only the one end piece 4 shown. Every final piece 4 has a hole 5 on, are connected to the pipes, not shown, for maintaining a circulation of the superheated steam. The heating element 3 and the hole 5 are in front of the interior 2 pressure tight. The fuel storage line 1 is in a conventional manner via holes in fittings 6 and one subsequent pipeline 7 each with an injection valve 8th in connection. Between two fittings 6 or a connection piece 6 and a final piece 4 is about the fuel storage line 1 Including an air gap in each case a casing pipe section 9 arranged.

Anstelle eines mit Heißdampf durchflossenen Heizelementes kann auch ein elektrisches Heizelement Verwendung finden.Instead of a heating element through which superheated steam flows, an electric heating element can also be used.

Mit Hilfe des vorstehend beschriebenen Heizelementes ist es möglich, bei kleinem Bauraum den Kraftstoff in der Kraftstoffspeicherleitung 1 gleichmäßig vorzuwärmen und dadurch einen sicheren Motorstart und Motorbetrieb mit Schweröl sicherzustellen. Außerdem verkürzt sich die Zeit bis zur Verfügbarkeit der Hubkolbenbrennkraftmaschine, weil der erforderliche Zeitraum, um von der kalten Maschine bis zur betriebsklaren Maschine zu kommen, verkürzt wird.With the help of the heating element described above, it is possible in a small space, the fuel in the fuel storage line 1 evenly preheat to ensure safe engine start and engine operation with heavy oil. In addition, the time to availability of the reciprocating internal combustion engine is shortened, because the time required to get from the cold machine to the operational machine is shortened.
