Abstract
Der Erfindung liegt die Aufgabe zu Grunde, einen Verbrennungsmotor und Verfahren zum Betrieb dieses Verbrennungsmotors zu entwickeln, bei dem die Nutzleistung und der Wirkungsgrad erheblich verbessert sowie die Abgasemissionen fast vollständig vermieden werden.Erreicht wird dies dadurch, dass der Verbrennungsmotor mindestens eine Brennkammer mit:- einem Einlass (7), welcher zur Lieferung von Inertgas geeignet ist,- einem Auslass (8), welcher zum Abtransport des erwärmten Inertgases und des Wassers aus der Brennkammer geeignet ist,- einer Verbindung zwischen Einlass (7) und Auslass (8), welche für den Transport und die Kühlung des Inertgases sowie die Abscheidung des Wassers geeignet ist,- mindestens ein Einblasventil (5), welches für die Sauerstoffdirekteinblasung geeignet ist und- mindestens ein Einblasventil (6), welches für die Wasserstoffdirekteinblasung geeignet ist, wobei die Einblasventile (5, 6) von einer Steuervorrichtung angesteuert werden, welche geeignet ist, den reinen Sauerstoff und den reinen Wasserstoff derart in den Brennraum einzublasen, dass ein zündfähiges Gemisch entsteht, aufweist, wobei durch Kolben (2), Zylinder (1) und Zylinderkopf (3) ein Brennraum ausgebildet wird.Derartige Verbrennungsmotoren werden zum Beispiel zum Antrieb von Fahrzeugen eingesetzt.The invention is based on the object of developing an internal combustion engine and a method for operating this internal combustion engine in which the useful power and efficiency are significantly improved and exhaust emissions are almost completely avoided. This is achieved by the internal combustion engine having at least one combustion chamber with: an inlet (7) which is suitable for the supply of inert gas, - an outlet (8) which is suitable for the removal of the heated inert gas and the water from the combustion chamber, - a connection between inlet (7) and outlet (8), which is suitable for the transport and cooling of the inert gas as well as the separation of the water, - at least one injection valve (5) which is suitable for direct oxygen injection and - at least one injection valve (6) which is suitable for direct hydrogen injection, the injection valves (5, 6) can be controlled by a control device which is suitable for the pure sow The substance and the pure hydrogen are to be blown into the combustion chamber in such a way that an ignitable mixture is produced, a combustion chamber being formed by the piston (2), cylinder (1) and cylinder head (3). Internal combustion engines of this type are used, for example, to drive vehicles .
Description
Die Erfindung bezieht sich auf einen Verbrennungsmotor nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Betrieb dieses Verbrennungsmotors nach dem Oberbegriff des Anspruchs 4.
Derartige Verbrennungsmotoren werden zum Beispiel zum Antrieb von Fahrzeugen eingesetzt.The invention relates to an internal combustion engine according to the preamble of
Such internal combustion engines are used, for example, to drive vehicles.
Durch die steigenden Anforderungen hinsichtlich der Verbesserung des Wirkungsgrades eines Verbrennungsmotors, bei gleichzeitiger Verminderung der Abgasemissionen, wurden durch die Hersteller von Verbrennungsmotoren zahlreiche technische Lösungen erarbeitet.
Diese bisherigen innermotorischen Lösungen beruhten jedoch auf:
- - einer Luftmengeerhöhung in dem durch einen Kolben, einen Zylinder und einen Zylinderkopf ausgebildeten Brennraum,
- - einer Anreicherung der Luft mit Sauerstoff oder
- - der Absenkung des Sauerstoffanteils in der Luft.
However, these previous in-engine solutions were based on:
- - an increase in the amount of air in the combustion chamber formed by a piston, a cylinder and a cylinder head,
- - an enrichment of the air with oxygen or
- - the lowering of the oxygen content in the air.
So wurde z.B. in der Offenlegungsschrift
Daraus lässt sich ableiten, dass sich durch eine Veränderung des Sauerstoffanteils der Luft die Nutzleistung, der Wirkungsgrad und die Abgasemissionen verbessern lassen. Damit ist allerdings nur eine innermotorische Minimierung der Abgasemissionen möglich, jedoch keine vollständige Vermeidung.From this it can be deduced that changing the oxygen content of the air can improve the useful power, the efficiency and the exhaust gas emissions. However, this only enables the exhaust emissions to be minimized within the engine, but not completely avoiding them.
Der Erfindung liegt daher die Aufgabe zu Grunde, einen Verbrennungsmotor und Verfahren zum Betrieb dieses Verbrennungsmotors zu entwickeln, bei dem die Nutzleistung und der Wirkungsgrad erheblich verbessert sowie die Abgasemissionen fast vollständig vermieden werden.The invention is therefore based on the object of developing an internal combustion engine and a method for operating this internal combustion engine, in which the useful power and the efficiency are considerably improved and the exhaust gas emissions are almost completely avoided.
Diese Aufgabe wird vorrichtungsseitig durch die kennzeichnenden Merkmale des Anspruchs 1 und verfahrensseitig durch die kennzeichnenden Merkmale des Anspruchs 4 gelöst. Zweckdienliche Ausgestaltungen ergeben sich vorrichtungsseitig aus den Unteransprüchen 2 und 3 sowie verfahrensseitig aus dem Unteranspruch 5.This object is achieved on the device side by the characterizing features of
Der neue Verbrennungsmotor und Verfahren zum Betrieb dieses Verbrennungsmotors beseitigen die genannten Nachteile des Standes der Technik.
Vorteilhaft bei der Anwendung des neuen Verbrennungsmotors und Verfahren zum Betrieb dieses Verbrennungsmotors ist es, dass Sauerstoff in reiner Form direkt über ein Ventil in den Brennraum eingeblasen wird. Dabei befindet sich in dem Zylinder keine Luft, sondern ein Inertgas oder ein Inertgas/Wasserstoffgemisch, wobei durch die Zugabe des Sauerstoffes ein zündfähiges Gemisch entsteht, welches entweder fremd gezündet wird oder sich von selbst entzündet und anschließend abgasemissionsfrei verbrennt. Dabei wird das erwärmte Inertgas dem Motor über einen Kühler wieder zurückgeführt und das entstehende Wasser über einen Wasserabscheider entfernt.The new internal combustion engine and method for operating this internal combustion engine eliminate the aforementioned disadvantages of the prior art.
When using the new internal combustion engine and method for operating this internal combustion engine, it is advantageous that pure oxygen is blown directly into the combustion chamber via a valve. There is no air in the cylinder, but an inert gas or an inert gas / hydrogen mixture, with the addition of the oxygen creating an ignitable mixture which is either ignited externally or ignites by itself and then burns without exhaust emissions. The heated inert gas is returned to the engine via a cooler and the water produced is removed via a water separator.
Der neue Verbrennungsmotor und Verfahren zum Betrieb dieses Verbrennungsmotors soll nun an einem Ausführungsbeispiel eines fremdgezündeten 4-Takt-Motors erläutert werden.The new internal combustion engine and method for operating this internal combustion engine will now be explained using an exemplary embodiment of a spark-ignited 4-stroke engine.

Mit dem Erreichen des oberen Totpunktes beginnt der Arbeitszyklus erneut mit dem 1. Takt.When the top dead center is reached, the work cycle starts again with the 1st cycle.
Vorrichtungsseitig ist es auch denkbar, dass nach dem Kühler
Dabei ist es dann auch denkbar, dass sich in dem Auffangbehälter ein Schwimmerventil befindet, welches bei einem definierten Füllstand öffnet und das Wasser an die Umgebung abgibt. Beim Erreichen eines definierten unteren Schwellwertes wird dieses Schwimmerventil wieder geschlossen, damit kein Inertgas entweicht.On the device side, it is also conceivable that after the cooler
It is then also conceivable that there is a float valve in the collecting container, which opens at a defined fill level and releases the water to the environment. When a defined lower threshold value is reached, this float valve is closed again so that no inert gas escapes.
Denkbar ist es auch, dass der fremdgezündete 4-Takt Prozess nur eine mögliche Anwendung für die Sauerstoffdirekteinblasung darstellt. So kann beispielsweise auch durch eine lokale Sauerstofferhöhung im Brennraum der Verbrennungsprozess eingeleitet werden, ohne dass es eine Zündkerze oder eine andere Form der Fremdzündung bedarf.
Zusätzlich lässt sich die Sauerstoffkonzentration im Brennraum beliebig dem jeweiligen Betriebszustandes des Verbrennungsmotors anpassen, wodurch eine höhere Verdichtung und dadurch ein deutlich verbesserter Wirkungsgrad ermöglicht werden.
Auch ist es denkbar, dass innerhalb eines Arbeitszyklus mehrfach über das Sauerstoffeinblasventil
Denkbar ist es auch, dass als Inertgas ein Edelgas oder Kohlenstoffdioxid eingesetzt wird.It is also conceivable that the externally ignited 4-stroke process is only one possible application for direct oxygen injection. For example, the combustion process can also be initiated by a local increase in oxygen in the combustion chamber without the need for a spark plug or any other form of external ignition.
In addition, the oxygen concentration in the combustion chamber can be adapted as required to the respective operating state of the internal combustion engine, which enables higher compression and thus a significantly improved degree of efficiency.
It is also conceivable that several times within a working cycle via the
It is also conceivable that a noble gas or carbon dioxide is used as the inert gas.
