Bei der Verbrennung des Kraftstoffs entstehende Hitze kann die Kraftstoffpumpe jedoch schädigen.An internal combustion engine generally has at least one fuel pump with which the fuel to be combusted is to be transported to a combustion chamber of the internal combustion engine. However, heat generated by combustion of the fuel can damage the fuel pump.

Offenbarung der ErfindungDisclosure of the invention
Vor diesem Hintergrund werden eine Kühlanordnung für eine Kraftstoffpumpe und ein Verfahren mit den Merkmalen der unabhängigen Patentansprüche vorgestellt. Weitere Ausgestaltungen der Erfindung ergeben sich aus den entsprechenden Unteransprüchen und der Beschreibung.Against this background, a cooling arrangement for a fuel pump and a method having the features of the independent claims are presented. Further embodiments of the invention will become apparent from the corresponding dependent claims and the description.
Die erfindungsgemäße Kühlanordnung und das erfindungsgemäße Verfahren sind für einen Zweikraftstoff-Verbrennungsmotor vorgesehen, mit dem in einem Flüssigbetrieb flüssiger Kraftstoff und in einem Gasbetrieb gasförmiger Kraftstoff verbrannt werden kann.The cooling arrangement according to the invention and the method according to the invention are provided for a two-fuel internal combustion engine with which liquid fuel can be burned in a liquid operation and gaseous fuel can be burned in a gas operation.
Mit der vorgestellten Kühlanordnung kann typischerweise für eine als Hochdruckpumpe (HDP) ausgebildete Kraftstoffpumpe, die bspw. zum Fördern von Benzin als flüssigem Kraftstoff ausgebildet ist, in einem Zweikraftstoff-Verbrennungsmotor, der als sog. Bi-Fuel Benzin Direkteinspritzmotor ausgebildet sein kann, ein Hochdruckkomponentenschutz während des Gasbetriebs, wenn als ein möglicher Kraftstoff ein gasförmiger Kraftstoff verbrannt wird, erreicht werden. Somit kann die Kraftstoffpumpe zusätzlich gekühlt werden, sofern im Gasbetrieb eine Kühlung durch flüssigen Kraftstoff, der auch im Gasbetrieb durch die Kraftstoffpumpe fließen kann, unzureichend ist.With the presented cooling arrangement can typically for a designed as a high-pressure pump (HDP) fuel pump, which is designed, for example, for conveying gasoline as a liquid fuel in a two-fuel internal combustion engine, which can be designed as a so-called. Bi-fuel gasoline direct injection engine, high pressure component protection during gas operation, when a gaseous fuel is burned as a possible fuel. Thus, the fuel pump can be additionally cooled, provided that in the gas mode cooling by liquid fuel, which can flow through the fuel pump in gas mode, is insufficient.
Hierzu kann die Kraftstoffpumpe als mindestens ein Kühlmodul in und/oder an einer Außenwandung mindestens einen als Bohrung ausgebildeten Kanal aufweisen, der an einem Kühlkreislauf anzuschließen bzw. angeschlossen ist, durch den als Kühlmittel bspw. Kühlwasser zu leiten ist.For this purpose, the fuel pump as at least one cooling module in and / or on an outer wall having at least one channel formed as a bore, which is connected to a cooling circuit or connected, is to be guided by the coolant as, for example, cooling water.
In Ausgestaltung ist auch möglich, dass in und/oder an der Außenwandung als mindestens ein Kühlmodul eine Wärmetauschrille angeordnet ist.In an embodiment, it is also possible for a heat exchange groove to be arranged in and / or on the outer wall as at least one cooling module.
Alternativ oder ergänzend kann als mindestens ein Kühlmodul in und/oder an der Außenwandung mindestens ein Wärmetauscher als mindestens ein Kühlmodul angeordnet sein. Ein derartiger Wärmetauscher kann ebenfalls zumindest einen als Bohrung ausgebildeten Kanal aufweisen, durch den als Kühlmittel bspw. Kühlwasser geleitet werden kann.Alternatively or additionally, at least one heat exchanger may be arranged as at least one cooling module in and / or on the outer wall as at least one cooling module. Such a heat exchanger may also have at least one channel formed as a bore, through which, for example, cooling water can be passed as coolant.
Mindestens eines dieser genannten Kühlmodule, bspw. der Wärmetauscher, kann der Kraftstoffpumpe optional und/oder modular als sog. "add on" und demnach als Anbauteil oder Ergänzungsteil zugeordnet sein.At least one of said cooling modules, for example the heat exchanger, can be assigned to the fuel pump optionally and / or modularly as a so-called "add on" and accordingly as an attachment or supplementary part.
Der Einsatz von Kühlmittel ist in Ausgestaltung dann vorgesehen, wenn der Verbrennungsmotor im Gasbetrieb betrieben wird, bei dem in zumindest einer Brennkammer des Verbrennungsmotors neben Luft, in der Regel neben Sauerstoff als Bestandteil der Luft, gasförmiger Kraftstoff, üblicherweise eine gasförmige Kohlenwasserstoffverbindung, verbrannt wird.The use of coolant is provided in an embodiment when the internal combustion engine is operated in gas operation, in which at least one combustion chamber of the internal combustion engine in addition to air, usually in addition to oxygen as part of the air, gaseous fuel, usually a gaseous hydrocarbon compound is burned.
Im Gasbetrieb kann als ergänzende Maßnahme eine Temperatur eines Kühlmittels des Verbrennungsmotors abgesenkt werden und/oder ein Motorlüfter ansteuert und somit gestartet werden, sobald der Verbrennungsmotor eines Kraftfahrzeugs vom Flüssigbetrieb in den Gasbetrieb wechselt. Zusätzlich kann durch die Kraftstoffpumpe auch im Gasbetrieb, bspw. über einen Rücklauf zu einem Kraftstofftank für flüssigen Kraftstoff, als weitere Kühlmaßnahme flüssiger Kraftstoff gespült werden.In gas operation, as a supplementary measure, a temperature of a coolant of the internal combustion engine can be lowered and / or an engine fan is actuated and thus started as soon as the internal combustion engine of a motor vehicle changes from liquid operation to gas operation. In addition, can be flushed by the fuel pump in the gas mode, for example. Via a return to a fuel tank for liquid fuel, as a further cooling measure liquid fuel.
Mit der Kühlanordnung können eine schnelle Alterung oder Zerstörung der Kraftstoffpumpe vermieden werden.With the cooling arrangement, rapid aging or destruction of the fuel pump can be avoided.
Somit ist es in Ausgestaltung möglich, eine maximal zulässige Temperatur der Kraftstoffpumpe im Gasbetrieb auf 100 °C zu beschränken.Thus, it is possible in design to limit a maximum allowable temperature of the fuel pump in the gas mode to 100 ° C.
Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und den beiliegenden Zeichnungen.Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.
