KurzbeschreibungSummary
Die vorliegende Erfindung betrifft eine Brennkraftmaschine mit nachgeschaltetem Bottoming-Cycle-Prozess, welcher als Arbeitsmedium Alkohol verwendet, der im Nachschaltprozess zumindest teilweise zu Synthesegas reformiert wird, wobei sowohl der Alkohol als auch das Synthesegas von der Brennkraftmaschine als Kraftstoff verwendet werden und gleichzeitig Arbeitsmedium im Nachschaltprozess sind.The present invention relates to an internal combustion engine with downstream bottoming cycle process, which uses alcohol as the working medium, which is at least partially reformed in the downstream process to synthesis gas, wherein both the alcohol and the synthesis gas are used by the internal combustion engine as fuel and at the same time working medium in the subsequent process are.
Stand der TechnikState of the art
Nach Stand der Technik werden heute Verbrennungsmotoren neben fossilen Kraftstoffen auch mit Alkoholkraftstoffen angetrieben. Dabei sind Methanol und Ethanol die am häufigsten verwendeten Alkohole. Betrieben werden die Verbrennungsmotoren mit bis zu 85% Alkoholgehalt im Kraftstoff. Dies ist hauptsächlich durch die schlechte Verdampfungsqualität der Kraftstoffe bei niedrigen Temperaturen begründet, was eine schlechte Startbarkeit des Motors bewirkt. Bei Verwendung von Alkoholkraftstoffen kommen zahlreiche Detailverbesserungen zur Anwendung, welche das Problem des Kraftstoffeintrages in das Schmiermittel Motoröl, die Ausnützung der höheren Klopffestigkeit der Alkohole sowie die Ausnützung der höheren Verdampfungsenthalpie gegenüber handelsüblichen Ottokraftstoffen, insbesondere zur Füllungs- und Leistungssteigerung, zum Ziel haben.According to the state of the art, internal combustion engines today are driven not only by fossil fuels but also by alcohol fuels. Methanol and ethanol are the most commonly used alcohols. The internal combustion engines are operated with up to 85% alcohol content in the fuel. This is mainly due to the poor vaporization quality of the fuels at low temperatures, which causes poor engine startability. When using alcohol fuels numerous detail improvements are used, which have the problem of the fuel input into the lubricant engine oil, the use of higher anti-knocking alcohols and the use of higher enthalpy of vaporization over commercial gasoline fuels, especially for filling and performance increase, the goal.
Katalysatoren sind in der gesamten Technik, im Anlagenbau und auch im Motorenbau weit verbreitet. In der Motorenentwicklung wurden neben verschiedenen Katalysatoren zur Abgasreinigung bereits Katalysatoren zur Reformierung alkoholhaltiger Kraftstoffe untersucht, siehe xxxx.Catalysts are widely used in the entire technology, in plant construction and also in engine construction. In engine development, catalysts for the reforming of alcohol-containing fuels have already been investigated in addition to various catalysts for exhaust gas purification, see xxxx.
Verschiedene Erfindungen (
Aufgabenstellung der ErfindungTask of the invention
Gegenstand der Erfindung ist die Steigerung des Wirkungsgrades eines Verbrennungsmotors mit Hilfe eines Nachschaltprozesses. Dabei liegt im Vordergrund, die chemischen und thermodynamischen Eigenschaften von Alkoholkraftstoffen auszunützen. Ebenso ist ein Automobiltaugliches mit guter Startfähigkeit und kundenwirksamen Verbrauchsvorteil Ziel der Erfindung.The invention is the increase in the efficiency of an internal combustion engine with the aid of a Nachschaltprozesses. The focus here is on exploiting the chemical and thermodynamic properties of alcohol fuels. Likewise, an automotive suitable with good startability and customer-effective consumption advantage of the invention.
Beschreibung der ErfindungDescription of the invention
Die vorliegende Erfindung betrifft eine Brennkraftmaschine, wahlweise mit Aufladevorrichtung, bei der das Abgas nach dem Abgas-Katalysator über einen Wärmetauscher geleitet wird, welcher auf der Gegenseite mit dem Alkoholkraftstoff als Arbeitsmedium durchströmt wird. Dieser Wärmetauscher ist in zwei Teile segmentiert, wobei der erste Teil als Verdampfer ausgeführt ist und der zweite, näher am Motor liegende, Teil katalytisch beschichtet ist, um eine Dissoziation des Kraftstoffes zu ermöglichen.The present invention relates to an internal combustion engine, optionally with charging device, in which the exhaust gas is passed to the exhaust catalyst via a heat exchanger, which is traversed on the opposite side with the alcohol fuel as the working medium. This heat exchanger is segmented into two parts, the first part being designed as an evaporator and the second, lying closer to the engine, part is catalytically coated to allow dissociation of the fuel.
Der Kraftstoff wird zunächst von der Vorförderpumpe (
Nach dem Austritt aus diesem Wärmetauscher liegt ein Gemisch aus dissoziertem Kraftstoff, bestehend aus H2 und CO, verdampften, nicht dissoziertem Kraftstoff sowie nicht-flüchtigen flüssigen Kraftstoffbestandteilen vor. Dieses Gemisch wird über eine Entspannungsvorrichtung (
Das Gasgemisch wird anschließend über einen Kondensator (
Das nach der Dissoziation im Reformer (
Die Zuführung des Synthesegases zur Verbrennungskraftmaschine (
Betrieb der KombinationsmaschineOperation of the combination machine
Das Verfahren zum Betrieb der Kombinationsmaschine aus Verbrennungskraftmaschine, Rankine-Prozess und Alkohol-Reformator mit der hier beschriebenen Vorrichtung, weist zusätzlich die Besonderheiten auf, dass abhängig von der Motortemperatur und dem aktuellen Betriebspunkt die Massenaufteilung der beiden Kraftstoffarten Alkoholkraftstoff und Synthesegas von einer elektronischen Motorsteuerung berechnet und permanent optimiert wird.The method for operating the combination engine of internal combustion engine, Rankine process and alcohol reformer with the device described here, additionally has the special features that calculated depending on the engine temperature and the current operating point, the mass distribution of the two fuel types alcohol fuel and synthesis gas from an electronic engine control and permanently optimized.
Durch geschickte Ansteuerung der beiden Injektorarten (
Weiterer Teil des Verfahrens ist daher die Startabstimmung des Verbrennungsmotors. Da ein Großteil der Emission im Start und kurze Zeit danach durch unverdampften Kraftstoff herrührt und zu diesem Zeitpunkt der Katalysator noch nicht betriebswarm ist, wird bei dem hier beschriebenen Verfahren ein Flüssiganteil im Start vermieden. Der Motorstart wird folglich, sofern genügend Synthesegas vorhanden ist, mit Synthesegas durchgeführt. In der anschließenden Warmlaufphase wird mit einem speziellen Algorithmus auf Flüssigkraftstoff umgeschaltet. Dies geschieht so lange, bis der Nachschaltprozess, bestehend aus Reformer (
Vorteilhaft bei diesem Verfahren ist, dass sowohl der Bottoming-Rankine-Prozess zur thermodynamischen Ausnutzung der im Abgas enthaltenen Exergie genutzt werden kann als auch der höhere Brennwert des Synthesegases. Der Heizwert des durch Reformation erzeugten Synthesegases liegt ca. 20–22% höher als der Heizwert des originalen Kraftstoffes. Gelingt es in einem Betriebspunkt genügend Synthesegas zu produzieren, um den Verbrennungsmotor zu 100% mit Synthesegas zu betreiben, so ist alleine dadurch eine Wirkungsgradsteigerung von 20–22% verbunden. Weiterhin wird noch die Überschussleistung an der Expansionsturbine (

Ausführungsbeispielembodiment
Beispielhaft sei die Integration der erfundenen Vorrichtung in ein PKW-Fahrzeug dargestellt.By way of example, the integration of the invented device in a car vehicle is shown.
Im Ausführungsbeispiel wird ein Verbrennungsmotor (
In der Motorsteuerung sind neben der Motorsteuerungssoftware nach Stand der Technik entsprechende zusätzliche Funktionen zur Steuerung des Rankineprozesses und des Reformers integriert und appliziert. Weitere Funktionen zur Motorregelung betreffen den Start, der Vorzugsweise mit Synthesegas betrieben wird, aber bei geringem Vorrat im Druckspeicher auch mit Flüssigkraftstoff erfolgen kann. Eine weitere Funktion regelt den Warmlauf bis zum Erreichen der Katalysatorbetriebstemperatur mit Synthesegas als Hauptbetriebsstoff. Ein ebenfalls in der Motorsteuerung applizierter Betriebsartenmanager schaltet danach wieder auch Alkoholkraftstoff um. Eine letzte Funktion berechnet den idealen Sollfüllstand des Druckspeichers und regelt diesen durch Variation der Kraftstoffaufteilung.In addition to the engine control software according to the prior art, additional engine control functions for controlling the Rankine process and the reformer are integrated and applied in the engine control. Other functions for engine control relate to the start, which is preferably operated with synthesis gas, but can also be done with liquid fuel at low supply in the accumulator. Another function regulates the warm-up until reaching the catalyst operating temperature with synthesis gas as the main operating material. A mode manager also applied in the engine control then switches alcohol fuel again. A final function calculates the ideal desired level of the pressure accumulator and regulates this by varying the fuel distribution.
