Description
Die Erfindung betrifft einen Verbrennungsmotor nach dem Oberbegriff des Anspruches 1 sowie einen Nach/Umrüstsatz für einen solchen Verbrennungsmotor nach dem Oberbegriff des Anspruches 11.The invention relates to an internal combustion engine according to the preamble of
Es sind Verbrennungsmotoren bekannt, die mit flüssigem Kraftstoff, wie Benzin oder Diesel, und gasförmigem Kraftstoff betrieben werden.There are internal combustion engines are known, which are operated with liquid fuel, such as gasoline or diesel, and gaseous fuel.
Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Verbrennungsmotor sowie den gattungsgemäßen Nach/Umrüstsatz so auszubilden, dass ein kostensparender und nur geringe Emissionen erzeugender Betrieb gewährleistet ist.The invention has the object of providing the generic internal combustion engine and the generic after / conversion kit in such a way that a cost-saving and low emissions generating operation is guaranteed.
Diese Aufgabe wird beim gattungsgemäßen Verbrennungsmotor erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 und beim gattungsgemäßen Nach/Umrüstsatz erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 11 gelöst.This object is achieved in the generic internal combustion engine according to the invention with the characterizing features of
Der erfindungsgemäße Verbrennungsmotor zeichnet sich dadurch aus, dass er im Normalbetrieb mit einer Mischung aus gasförmigem und flüssigem Kraftstoff betrieben wird. Sobald jedoch während des Betriebes ein schädlicher HC-Überschuss auftritt, wird der Verbrennungsmotor nur noch mit einer Art von Kraftstoff betrieben. Bei einem Dieselmotor wird in diesem Falle nur Dieselkraftstoff eingesetzt. Handelt es sich um einen Ottomotor, dann kann wahlweise Benzin oder der gasförmige Kraftstoff allein eingesetzt werden, um die HC-Werte in den zulässigen Wertebereich zu bringen. Um diesen HC-Überschuss zu erfassen, können beispielsweise Sensoren eingesetzt werden, die die HC-Werte im Abgas des Verbrennungsmotors erfassen und die Messwerte als Signale einer Steuereinheit zuführen. Mit ihr erfolgt dann eine Steuerung oder auch Regelung derart, dass der HC-Wert im Abgas wieder in einen zulässigen Bereich gelangt. Dann wird mit der Steuereinheit wiederum ein Mischbetrieb eingestellt, bei dem der Verbrennungsmotor mit einer Mischung aus flüssigem und gasförmigem Kraftstoff betrieben wird.The internal combustion engine according to the invention is characterized in that it is operated in normal operation with a mixture of gaseous and liquid fuel. However, as soon as a harmful HC surplus occurs during operation, the internal combustion engine is operated with only one type of fuel. In a diesel engine only diesel fuel is used in this case. If it is a gasoline engine, either gasoline or the gaseous fuel can be used alone to bring the HC values within the permissible value range. To detect this excess HC, for example, sensors can be used which detect the HC values in the exhaust gas of the internal combustion engine and supply the measured values as signals to a control unit. With it then takes place a control or regulation such that the HC value in the exhaust gas again reaches a permissible range. Then, a mixing operation is again set with the control unit, in which the internal combustion engine is operated with a mixture of liquid and gaseous fuel.
Vorteilhaft erfolgt der Betrieb in nur einer Kraftstoffart beim Start und/oder im Leerlauf des Verbrennungsmotors. Hierbei wird vorzugsweise flüssiger Kraftstoff eingesetzt.Advantageously, the operation takes place in only one type of fuel when starting and / or idling the internal combustion engine. In this case, preferably liquid fuel is used.
Auch im Volllastbereich können erhöhte HC-Werte auftreten, so dass auch in diesem Bereich der Verbrennungsmotor vorteilhaft mit nur einer Art von Kraftstoff betrieben wird. Es ist aber auch möglich, im Volllastbereich flüssigen und gasförmigen Kraftstoff einzusetzen. Dadurch kann der Wirkungsgrad und auch die Leistung des Verbrennungsmotors erhöht werden.Increased HC values can also occur in the full load range, so that even in this area the internal combustion engine is advantageously operated with only one type of fuel. But it is also possible to use in the full load liquid and gaseous fuel. As a result, the efficiency and the performance of the internal combustion engine can be increased.
Schließlich ist es auch möglich, auf einen Ein-Kraftstoff-Betrieb umzuschalten, wenn der Verbrennungsmotor im Transientenbereich arbeitet.Finally, it is also possible to switch to one-fuel operation when the engine is operating in the transient region.
Der Verbrennungsmotor wird bei Diesel als flüssiger Kraftstoff in dem Bereich, in dem ein schädlicher HC-Überschuss entsteht, vorteilhaft ausschließlich mit Diesel betrieben.The diesel engine is advantageously operated exclusively with diesel as liquid fuel in the region in which a harmful excess of HC is produced.
Ist der Verbrennungsmotor ein Ottomotor, dann wird vorteilhaft Benzin oder der gasförmige Kraftstoff als alleiniger Kraftstoff in dem Bereich eingesetzt, in dem beim Mischbetrieb ein schädlicher HC-Überschuss entsteht.If the internal combustion engine is a gasoline engine, gasoline or gaseous fuel is advantageously used as sole fuel in the region in which a harmful excess of HC occurs during mixed operation.
Bei einer vorteilhaften Ausführungsform wird der flüssige bzw. gasförmige Kraftstoff exzentrisch nahe am Einlassventil in ein Saugrohr oder in einen Saugkanal eingespritzt.In an advantageous embodiment, the liquid or gaseous fuel is injected eccentrically close to the inlet valve in a suction pipe or in a suction channel.
Bei einem Dieselmotor wird der gasförmige Kraftstoff durch eine Einspritzdüse exzentrisch nahe am Einlassventil in das Saugrohr oder in den Saugkanal eingespritzt. Beim Öffnen des Einlassventils wird das Gas/Luft-Gemisch in den Verbrennungsraum eingesaugt. Sobald die Verdichtung beginnt, wird der Dieselkraftstoff eingespritzt und alles entzündet sich.In a diesel engine, the gaseous fuel is injected through an injector eccentrically close to the intake valve into the intake manifold or into the intake port. When opening the inlet valve, the gas / air mixture is sucked into the combustion chamber. Once the compression starts, the diesel fuel is injected and everything ignites.
Bei einem Otto- bzw. Benzinmotor erfolgt die Einspritzung des flüssigen Kraftstoffes in das Saugrohr nahe dem Einlassventil. Das Flüssigkraftstoff/Luft-Gemisch strömt beim Öffnen des Einlassventils in den Verbrennungsraum. Der gasförmige Kraftstoff wird über wenigstens eine im Zylinderkopf vorgesehene Gasdüse direkt in den Verbrennungsraum eingedüst.In an Otto or gasoline engine, the injection of the liquid fuel into the intake manifold takes place near the intake valve. The liquid fuel / air mixture flows into the combustion chamber when the intake valve is opened. The gaseous fuel is injected directly into the combustion chamber via at least one gas nozzle provided in the cylinder head.
Vorteilhaft ist der Einspritzdruck des gasförmigen Kraftstoffes durch wenigstens ein Druckregelventil an alle Betriebszustände anpassbar. Dadurch ist es möglich, den Einspritzdruck lastabhängig und/oder emissionsabhängig und/oder drehzahlabhängig zu regeln.Advantageously, the injection pressure of the gaseous fuel by at least one pressure control valve to all operating conditions customizable. This makes it possible to regulate the injection pressure load-dependent and / or emission-dependent and / or speed-dependent.
Der erfindungsgemäße Nach/Umrüstsatz ermöglicht es, bestehende Verbrennungsmotoren einfach umzurüsten. Es wird lediglich die bestehende Sauganlage abgenommen und die Halteplatte zwischen den Zylinderköpfen des Verbrennungsmotors und der Saugrohranlage eingesetzt. Die Halteplatte enthält die Einspritzdüsen für den gasförmigen Kraftstoff, an welche die Zuführleitungen angeschlossen werden können. Es ist auch möglich, dass die Zuführleitungen bereits an die Einspritzdüsen angeschlossen sind.The Nach / Umrüstsatz invention makes it possible to convert existing internal combustion engines easily. It is only the existing intake system removed and used the retaining plate between the cylinder heads of the engine and the intake manifold. The holding plate contains the gaseous fuel injection nozzles to which the supply lines can be connected. It is also possible that the supply lines are already connected to the injection nozzles.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen. Further features of the invention will become apparent from the other claims, the description and the drawings.
Die Erfindung wird nachstehend anhand zweier in den Zeichnungen dargestellter Ausführungsformen näher erläutert. Es zeigenThe invention is explained below with reference to two embodiments shown in the drawings. Show it

Auf die beschriebene Weise ist es somit möglich, die Zuführung des jeweiligen Kraftstoffes optimal im Hinblick auf die Emissionswerte und den Kraftstoffverbrauch für jeden Betriebspunkt (Drezahl/Drehmoment) einzustellen.In the manner described, it is thus possible to set the supply of the respective fuel optimally with regard to the emission values and the fuel consumption for each operating point (speed / torque).

Schließlich ist eine Programmierung auch im Hinblick auf eine große Reichweite möglich. Dieser Gesichtspunkt spielt beispielsweise eine Rolle, wenn das Tankstellennetz nicht sehr dicht ist.After all, programming is also possible with regard to a large range. This aspect plays a role, for example, when the filling station network is not very dense.
Die aufgeführten Beispiele zeigen, dass die Programmierung im Hinblick auf verschiedene Kriterien erfolgen kann, auch in Kombination miteinander. The examples given show that the programming can be done in terms of different criteria, even in combination.
Der gasförmige Kraftstoff wird der Ansaugluft zugemischt und der flüssige Kraftstoff direkt eingespritzt. Durch die Voreinspritzung des flüssigen Kraftstoffes wird die Verbrennung eingestellt, so dass die Haupteinspritzung dann in bereits entzündetes Gas in den Brennraum erfolgt.The gaseous fuel is added to the intake air and the liquid fuel is injected directly. By the pre-injection of the liquid fuel, the combustion is stopped, so that the main injection then takes place in already ignited gas into the combustion chamber.

Beim beschriebenen Ausführungsbeispiel wird der gasförmige Kraftstoff vom Gastank
Der Anteil an flüssigem Kraftstoff kann bis etwa zu 60% durch den gasförmigen Kraftstoff ersetzt werden. Da der gasförmige Kraftstoff wesentlich kostengünstiger als der flüssige Kraftstoff ist, ergibt sich eine erhebliche Einsparung an Kraftstoffverbrauchskosten. Dabei führt dieser teilweise Ersatz des flüssigen durch den gasförmigen Kraftstoff zu keiner Beeinträchtigung der Motorleistung, des Drehmoments sowie der Lebensdauer des Verbrennungsmotors. Der gasförmige Kraftstoff wird sehr homogen verbrannt.The proportion of liquid fuel can be replaced up to about 60% by the gaseous fuel. Since the gaseous fuel is much cheaper than the liquid fuel, there is a significant saving in fuel consumption costs. In this case, this partial replacement of the liquid by the gaseous fuel leads to no impairment of the engine power, the torque and the life of the internal combustion engine. The gaseous fuel is burned very homogeneously.

Mit der neuen Vorrichtung lassen sich bei Diesel-Verbrennungsmaschinen die EURO-Normen III bis V sehr einfach erreichen. Die NOx- sowie die Partikel-Emissionen können bis zu 50% verringert werden, wobei auch der CO2-Ausstoß erheblich vermindert wird.With the new device, the EURO standards III to V can be very easily achieved in diesel internal combustion engines. The NOx and particulate emissions can be reduced by up to 50%, while significantly reducing CO 2 emissions.
Die Ausführungsform gemäß
Auch bei dieser Ausführungsform ergeben sich für den Autofahrer erhebliche Vorteile, insbesondere Kostenersparnisvorteile, weil der gasförmige Kraftstoff wesentlich preisgünstiger ist als der flüssige Kraftstoff, vorzugsweise Benzin. Darüber hinaus wird zum Einspritzen des flüssigen Kraftstoffes keine teure Hochdruckpumpe und auch kein teures Hochdruckrail benötigt.Also in this embodiment, significant benefits for the motorist, in particular cost savings advantages, because the gaseous fuel is much cheaper than the liquid fuel, preferably gasoline. In addition, no expensive high-pressure pump and no expensive high-pressure rail is required for injecting the liquid fuel.
Im Vergleich mit einem Verbrennungsmotor, der ausschließlich mit gasförmigem Kraftstoff betrieben wird, ergibt sich bei der gemischten Verwendung von flüssigem und gasförmigen Kraftstoff eine Einsparung um bis zu etwa 30%. Dabei sind die Leistung und das Drehmoment des Verbrennungsmotors
Die Verteilung des flüssigen und des gasförmigen Kraftstoffes wird vorteilhaft an die Lastpunkte angepasst. Dabei werden die Vorteile der Kraftstoffe ausgenutzt. Der flüssige Kraftstoff ist durch seine Energiedichte und schnelle Verbrennung gekennzeichnet. Darum wird der flüssige Kraftstoff bevorzugt bei dynamischen Beschleunigungsvorgängen und im Leerlauf eingesetzt. Bei Teillast und bei konstanten Betriebsbedingungen wird der gasförmige Kraftstoff zugesetzt. Der zugemischte Anteil des gasförmigen Kraftstoffes wird für jeden Betriebspunkt im Hinblick auf Kraftstoffverbrauch, CO2-Emissionen und HC- und NOx-Emissionen optimiert. Die Betriebspunkte werden mit unterschiedlichen Eindüsdrücken und optimierten Eindüszeitpunkten betrieben. Bei Volllast wird der gasförmige Kraftstoff möglichst spät mit hohen Drücken eingedüst. Da er durch die Expansion von beispielsweise 220 bar im Gastank
Erdgas ist durch eine Vergleichsoktanzahl von 130 gekennzeichnet. Durch das kühlere Gemisch und die hohe Gemischoktanzahl kann das Verdichtungsverhältnis des Motors angehoben werden, so dass das Volllastdrehmoment gleich bzw. höher und der Kraftstoffverbrauch niedriger wird als im reinen Benzinbetrieb. Durch das größere Verdichtungsverhältnis wird auch der Teillastverbrauch verbessert. Durch den Gas-Flüssig-Kraftstoff-Mischbetrieb bleibt die Reichweite des reinen Flüssigkraftstoffbetriebes erhalten und die Gasdüsen nehmen einen kleineren Einbauraum ein, der es erlaubt, z. B. die Benzin-Gas-Düsen ohne große Änderungen am Motor durch Gas-Einspritzdüsen zu ersetzen.Natural gas is characterized by a reference octane number of 130. By the cooler mixture and the high mixture octane number, the compression ratio of the engine can be increased, so that the full load torque is equal to or higher and the fuel consumption is lower than in pure gasoline operation. Due to the larger compression ratio and the partial load consumption is improved. Due to the gas-liquid-fuel mixing operation, the range of pure liquid fuel operation is maintained and the gas nozzles occupy a smaller installation space, which allows, for. B. to replace the gasoline gas nozzles without major changes to the engine by gas injectors.
Anstelle von Benzin können auch Methanol, Ethanol oder ähnliche Kraftstoffe eingesetzt werden. Ebenso kann als gasförmiger Kraftstoff außer Erdgas beispielsweise auch Flüssiggas (LPG), Biogas, Wasserstoff und dergleichen verwendet werden.Instead of gasoline, methanol, ethanol or similar fuels can be used. Likewise, as the gaseous fuel other than natural gas, for example, liquid gas (LPG), biogas, hydrogen, and the like can also be used.
Auch bei dieser Ausführungsform kann der Verbrennungsmotor
