Abstract
Es wird ein Verfahren vorgestellt, das den, unter den gängigen Kraftstoffen einzigartigen, Doppelcharakter von Flüssiggas, sowohl als Kraftstoff für eine Verbrennungskraftmaschine als auch als Kältemittel in einem Kühlkreislauf genutzt werden zu können, in einem einzigen gekoppelten System gleichzeitig nutzt. Durch Koppelung der Kraftstoffzuführung zu den Einspritzventilen an der passenden Stelle des Klimakreislaufes wird ein Teil des Klimakreislaufes gleichzeitig als Zuführungsgruppe der Kraftstoffeinspritzung genutzt. Zusätzlich werden Verdampfer des Klimakreislaufes nicht nur für die Klimatisierung eines Innenraumes, z. B. eines Kraftfahrzeuges, genutzt, sondern auch für die Kühlung der der Verbrennungskraftmaschine zugeführten Verbrennungsluft bis unter den Gefrierpunkt von Wasser. Dadurch verbessert sich der thermodynamsiche Wirkungsgrad des Verbrennungsprozesses weit über die Grenzen des bisher bei Ottomotoren Erreichbaren hinaus.A method is presented that uses the dual character of LPG, which is unique among common fuels, both as fuel for an internal combustion engine and as refrigerant in a refrigeration cycle, in a single coupled system at the same time. By coupling the fuel supply to the injectors at the appropriate point of the air conditioning circuit part of the air conditioning circuit is used simultaneously as a feed group of the fuel injection. In addition, evaporators of the air conditioning circuit not only for the air conditioning of an interior, z. As a motor vehicle, used, but also for the cooling of the internal combustion engine supplied combustion air to below freezing point of water. This improves the thermodynamic efficiency of the combustion process far beyond the limits of what was previously achievable with gasoline engines.
Description
Die Erfindung betrifft ein Verfahren zur Einbringung von Flüssiggas oder einer seiner Komponenten oder einer Mischung seiner Komponenten in das Kraftstoffzuführungssystem einer Verbrennungskraftmaschine mit innerer zyklischer Verbrennung.The The invention relates to a method for introducing LPG or one of its components or a mixture of its components into the fuel supply system an internal combustion engine with internal cyclic combustion.
Stand der TechnikState of the art
Verbrennungskraftmaschinen, die den Kraftstoff Flüssiggas dem Brennraum einer Verbrennungskraftmaschine indirekt über die Ansaugleitung der Verbrennungsluft zuführen, nutzen überwiegend das Verdampfungsverfahren um das Flüssiggas in den Zuführungskanal für die Verbrennungsluft einzubringen. Hierbei drückt sich das Flüssiggas aus dem Tank durch seinen eigenen Dampfdruck in einen kühlwasserbeheizten Verdampfer in dem es aus der Mischphase vollständig in die Gasphase überführt wird. Vom Verdampfer aus wird das gasförmige Flüssiggas unter Überdruck einer eigenen Verteilerleiste zugeführt, von der aus jedem Zylinder, rechnergesteuert über getaktete Elektromagnetventile, für jeden Verbrennungstakt die passende Menge gasförmigen Kraftstoffes in die einströmende Verbrennungsluft eingeblasen wird. Diese Systeme können nur bivalent betrieben werden, denn sie benötigen neben dem Flüssiggas, zum Starten der Verbrennungskraftmaschine einen weiteren Kraftstoff, vorzugsweise Benzin. Erst wenn die Verbrennungskraftmaschine ausreichend Wärme für den Verdampfer abgibt kann dieser auf den Betrieb mit Flüssiggas umgestellt werden.Internal Combustion Engines, the fuel LPG the combustion chamber of an internal combustion engine indirectly over the Feed the intake line into the combustion air, mainly use it Evaporation process to the liquefied gas in the feed channel for the Incorporate combustion air. This expresses the liquefied gas from the tank by its own steam pressure into a cooling water-heated Evaporator in which it is completely transferred from the mixing phase in the gas phase. From the evaporator, the gaseous LPG under overpressure supplied to its own distribution bar, from which each cylinder, computer controlled via clocked solenoid valves, for each combustion cycle the appropriate amount of gaseous Fuel in the incoming Combustion air is blown. These systems can only be operated bivalent, because they need in addition to the LPG, to start the internal combustion engine another fuel, preferably gasoline. Only when the internal combustion engine is sufficient Heat for the evaporator gives off this can be switched to operation with LPG.
Einspritzsysteme, die das Flüssiggas über eine Pumpe im Flüssiggastank flüssig bis zu den Einspritzventilen für das Flüssiggas führen und das Flüssiggas flüssig in den Zuführungskanal für die Verbrennungsluft vor die Einlassventile spritzen, existieren ebenfalls, konnten sich bisher aber am Markt nicht durchsetzen.injection systems, the liquefied gas over a Pump in liquefied gas tank liquid up to the injectors for the liquefied gas to lead and the liquefied gas liquid in the feed channel for the Combustion air splash in front of the intake valves, also exist, but so far could not prevail on the market.

Genutzt wird diese Eigenschaft der Bestandteile von Flüssiggas hingegen in der Kältetechnik, beispielsweise im Kältekreislauf von Haushaltskühlschränken.Used However, this property of the components of liquefied gas, however, in refrigeration, for example in the refrigeration cycle of household refrigerators.
Dem in den Patentansprüchen beschriebenen Verfahren liegt das Problem zugrunde, den Kraftstoffzuführungsprozess thermisch stabiler zu gestalten und durch die Nutzung der Kühlwirkung der Flüssiggasverdampfung die Effizienz des thermodynamischen Kreisprozesses zu erhöhen, die sich in Leistungserhöhung bei verringertem spezifischem Verbrauch niederschlägt.the in the claims described method is based on the problem, the fuel supply process thermally stable and by the use of the cooling effect the liquefied gas evaporation to increase the efficiency of the thermodynamic cycle, the in power increase at reduced specific consumption.
Vorteile der ErfindungAdvantages of the invention
Diese Probleme werden durch das in den Patenansprüchen beschriebene Verfahren gelöst. Das vorliegende Verfahren besitzt Vorteile auf mehreren Ebenen. Es spart Bauteile ein, macht die Kraftstoffzuführung des Kraftstoffes Flüssiggas thermisch robuster und erhöht die Effizienz des thermodynamischen Kreisprozesses.These Problems are solved by the method described in the claims solved. The present method has advantages at several levels. It saves Components, makes the fuel supply of the fuel LPG thermally more robust and increased the efficiency of the thermodynamic cycle.
Im überwiegenden Teil der Kraftfahrzeuge, die neu auf den Markt kommen, sind Klimaanlagen eingebaut. Damit ist die Voraussetzung vorhanden, ohne wesentlichen zusätzlichen Kostenaufwand an Stelle des Kältekreislaufes mit dem bisher üblichen Kältemittel R134a einen Kältekreislauf mit dem Kraftstoff Flüssiggas als Kältemittel zu etablieren. In diesem Falle erübrigt sich eine Pumpe im Flüssiggastank und auch der Verdampfer, weil der Klimakompressor das Flüssiggas, das in dem hier beschriebenen Verfahren sowohl Kraftstoff als auch Kältemittel ist, gasförmig aus der Gasphase im Kraftstofftank ansaugt, unabhängig davon, welche Temperatur das Flüssiggas momentan besitzt. Dadurch gewinnt das Kraftstoffzuführungssystem an thermischer Stabilität. Gerade in Systemen mit flüssiger Einspritzung des Flüssiggases musste jeder Wärmeeintrag in den Kraftstoff auf seinem Weg aus dem Flüssiggastank zu den Einspritzventilen durch erhöhten Druck oder zusätzlichen Kühlaufwand kompensiert werden, während an dieser Stelle des Kältekreislaufs zusätzliche Erwärmung willkommen ist, da sie die Gasphase des Kraftstoffes stabilisiert und sicherstellt, dass dem Kompressor ausschließlich Flüssiggas in der Gasphase zugeführt wird.In the vast majority Part of the motor vehicles that are new to the market, air conditioning systems are installed. This is the prerequisite, without significant additional Cost in place of the refrigeration cycle with the usual refrigerant R134a a refrigeration cycle with the fuel LPG as a refrigerant to establish. In this case, a pump is unnecessary in the liquefied gas tank and also the evaporator because the air conditioning compressor that in the method described here both fuel and Refrigerant is, gaseous aspirated from the gas phase in the fuel tank, regardless of what temperature the liquefied gas currently owns. This gains the fuel delivery system at thermal stability. Just in systems with liquid Injection of the liquefied gas had every heat input into the fuel on its way out of the liquefied gas tank to the injectors through raised Pressure or additional cooling requirements be compensated while at this point of the refrigeration cycle additional warming is welcome because it stabilizes the gas phase of the fuel and ensures that only liquid gas in the gas phase is supplied to the compressor.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass die Klimatisierung des Innenraumes an Stelle des Verdampfers nur einen Wärmetauscher benötigt.One Another advantage of the method according to the invention is that the air conditioning of the interior in place of the evaporator only one heat exchanger needed.
Wesentlich ist auch der Gewinn an thermodynamischer Effizienz bewirkt durch die Kühlung der Ansaugluft durch den Kühleffekt des im Kältekreislauf verdampfenden Flüssiggases. Berechnungen zeigen, dass eine Verringerung der Anfangstemperatur im thermodynamischen Kreisprozesses der Verbrennung im Vergleich zu einer Erhöhung der Endtemperatur um den gleichen Temperaturbetrag, die Effizienz des Prozesses um beinahe das Dreifache erhöht.Also important is the gain in thermodynamic efficiency caused by the cooling of the Intake air due to the cooling effect of the liquefied gas evaporating in the refrigeration circuit. Calculations show that reducing the initial temperature in the thermodynamic cycle of combustion as compared to increasing the final temperature by the same amount of temperature increases the efficiency of the process by almost three times.
Der Kältekreislauf des Flüssiggases, erlaubt eine Abkühlung der Verbrennungsluft unter die Umgebungstemperatur und unter den Gefrierpunkt des Wassers. Dies macht es möglich, die Verdichtung des Motors erheblich zu erhöhen. Da die Endtemperatur des Verbrennungsprozesses dabei nicht erhöht wird, lassen sich auch beim Otto-Motor Verdichtungsverhältnisse darstellen, die ihre Grenze nicht mehr in der Temperatur, sondern in der mechanischen Belastbarkeit des Materials finden, wodurch thermodynamische Wirkungsgrade realisiert werden können, die dem Wirkungsgrad des Dieselverfahrens ebenbürtig sind oder ihn sogar übertreffen und weit über die Grenzen des bisher bei Ottomotoren erreichbaren thermodynamischen Wirkungsgrade hinaus.Of the Refrigeration circuit the liquefied gas, allows a cool down the combustion air below the ambient temperature and below the Freezing point of the water. This makes it possible the compression of the Significantly increase the engine. Since the final temperature of the combustion process is not increased, can also be the gasoline engine compression ratios represent their limit is no longer in the temperature, but find in the mechanical resilience of the material, thereby thermodynamic Efficiencies can be realized, the efficiency equal to the diesel process are or even surpass him and far beyond the limits of the previously achievable in gasoline engines thermodynamic Efficiencies addition.
Das wiederum hat zur Folge, dass Drehmoment und Leistung wesentlich steigen, während sich gleichzeitig der spezifische Verbrauch ähnlich deutlich verringert.The In turn, the result is that torque and power are essential rise while At the same time the specific consumption is similarly reduced.
