Description
Stand der TechnikState of the art
Erdgas ist bei Normaltemperaturen selbst unter hohem Druck in guter Näherung als gasförmig zu betrachten (CNG, d. h. „Compressed Natural Gas“). Um verdichtetes Erdgas in einen Brennraum einer Brennkraftmaschine einzublasen sind spezielle Einblas- bzw. Einspritzventile erforderlich, die sich von denen zur Direkteinspritzung von Benzin oder Dieselkraftstoff in vielerlei Hinsicht (z.B. im Spritzlochdurchmesser) unterscheiden. Da flüssiges Erdgas (LNG, d. h. „Liquefied Natural Gas“) ein deutlich geringeres spezifisches Volumen als gasförmiges Erdgas besitzt, wird es für mobile Anwendungen in der Regel in flüssiger Form vorgehalten. Hierzu wird das Erdgas auf Temperaturen von etwa -160°C herunter gekühlt.At normal temperatures, even at high pressure, natural gas is to be regarded as a good approximation as gaseous (CNG, ie "compressed natural gas"). In order to inject compressed natural gas into a combustion chamber of an internal combustion engine, special injection valves are required which differ from those for direct injection of gasoline or diesel fuel in many respects (for example, in the spray hole diameter). As Liquefied Natural Gas (LNG) has a significantly lower specific volume than gaseous natural gas, it is usually stored in liquid form for mobile applications. For this purpose, the natural gas is cooled down to temperatures of about -160 ° C down.
Das in den Brennraum einer Brennkraftmaschine eingebrachte Erdgas wird durch ein Hilfsmittel oder ein Hilfsmedium zum Zünden gebracht. Beispielsweise kann flüssiger Dieselkraftstoff als Hilfsmedium verwendet werden, da dieser im Unterschied zu Erdgas bei den üblicherweise gegebenen Bedingungen selbstzündend ist. In diesem Fall gilt es zwei unterschiedliche Kraftstoffarten in den Brennraum der Brennkraftmaschine einzubringen.The natural gas introduced into the combustion chamber of an internal combustion engine is caused to ignite by an auxiliary or auxiliary medium. For example, liquid diesel fuel can be used as an auxiliary medium since, unlike natural gas, it is self-igniting in the conditions usually given. In this case, it is necessary to introduce two different types of fuel into the combustion chamber of the internal combustion engine.
Zur Einbringung zweier unterschiedlicher Kraftstoffarten in den Brennraum einer Brennkraftmaschine kann ein sogenannter Zweistoffinjektor verwendet werden. In einem solchen Zweistoffinjektor werden die beiden Kraftstoffe getrennt geführt, um eine Vermischung außerhalb des Brennraums zu verhindern.For introducing two different types of fuel into the combustion chamber of an internal combustion engine, a so-called two-fluid injector can be used. In such a two-fluid injector, the two fuels are fed separately to prevent mixing outside of the combustion chamber.

Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Kraftstofffördereinrichtung und das Verfahren zur Förderung von Kraftstoff mit den Merkmalen gemäß der unabhängigen Ansprüche haben den Vorteil, dass der Druck im Hochdruckrail bei Bedarf durch eine Einrichtung zum Entleeren des Hochdruckrails reduziert werden kann.The fuel delivery device according to the invention and the method for delivering fuel with the features according to the independent claims have the advantage that the pressure in the high-pressure rail can be reduced if necessary by a device for emptying the high-pressure rail.
Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren zeichnen sich besonders durch ihre hohe Flexibilität aus, was den Ausgleich von Druckschwankungen angeht. Eine Reduzierung oder Erhöhung des Druckes im Hochdruckrail kann innerhalb kürzester Zeit erfolgen.The device according to the invention and the method according to the invention are characterized in particular by their high flexibility with regard to the compensation of pressure fluctuations. A reduction or increase in the pressure in the high-pressure rail can be done within a very short time.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Kraftstofffördereinrichtung angegeben.In the dependent claims advantageous refinements and developments of the fuel delivery device according to the invention are given.
Es ist von Vorteil, wenn der Druck des gasförmigen Kraftstoffes im Gasraum durch die Hydraulikflüssigkeit kontrollierbar ist, da der Druck auf diese Weise variabel einstellbar ist.It is advantageous if the pressure of the gaseous fuel in the gas space is controllable by the hydraulic fluid, since the pressure is variably adjustable in this way.
Aufgrund der geringen Kosten ist es vorteilhaft, wenn die Hydraulikflüssigkeit, durch die Pumpe aus dem Hydrauliktank in den Hydraulikraum förderbar ist.Due to the low cost, it is advantageous if the hydraulic fluid can be conveyed by the pump from the hydraulic tank in the hydraulic chamber.
Eine Anordnung mit einem Ventil in einer Entleerungsleitung zwischen Gasraum und Hochdruckrail ist von Vorteil, da auf diese Weise die Druckerhöhung oder Reduzierung im Hochdruckrail gesteuert werden kann.An arrangement with a valve in a drain line between the gas space and the high-pressure rail is advantageous, since in this way the pressure increase or reduction in the high-pressure rail can be controlled.
Vorteilhaft ist flüssiger Kraftstoff, insbesondere Diesel, als Hydraulikflüssigkeit, da dieser bereits im Kraftfahrzeug vorhanden ist.Advantageously, liquid fuel, in particular diesel, as hydraulic fluid, since this is already present in the motor vehicle.
Es ist von Vorteil, wenn der Hochdruckspeicher als Kolbenspeicher ausgebildet ist, da dieser den benötigte Druckbereich von 200 bis 500 bar umfasst.It is advantageous if the high-pressure accumulator is designed as a piston accumulator, since this comprises the required pressure range of 200 to 500 bar.
Es ist vorteilhaft, wenn nach einem Motorstopp das Volumen der Hydraulikflüssigkeit im Hochdruckspeicher reduziert wird und das Volumen des gasförmigen Kraftstoffes im Hochdruckspeicher erhöht wird, da auf diese Weise das Volumen des gasförmigen Kraftstoffes im Hochdruckspeicher maximiert wird und der Druck im Hochdruckrail maximal reduziert wird.It is advantageous if, after an engine stop, the volume of the hydraulic fluid in the high-pressure accumulator is reduced and the volume of the gaseous fuel in the high-pressure accumulator is increased, since in this way the volume of the gaseous fuel in the high-pressure accumulator is maximized and the pressure in the high-pressure rail is maximally reduced.
Es ist von Vorteil, wenn mit einer einzigen Hochdruckpumpe sowohl der Abtrieb für die weitere Pumpe (Hydraulikpumpe) zum Betrieb des Kolbenspeichers in der Einrichtung zum Entleeren von Umgebungsdruck auf Betriebsdruck (200 bar bis 500 bar) als auch die Dieselhochdruckpumpe für die Dieseleinspritzung betrieben werden. Dies ist besonders dann sinnvoll, wenn die verwendete Hydraulikflüssigkeit zum Betreiben der Kolbenspeicher am Gasrail Diesel ist.It is advantageous if both the output for the further pump (hydraulic pump) for operating the piston accumulator in the device for discharging ambient pressure to operating pressure (200 bar to 500 bar) and the diesel high-pressure pump for diesel injection are operated with a single high-pressure pump. This is particularly useful if the hydraulic fluid used to operate the piston accumulator on the gas rail is diesel.
