Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betrieb eines Verbrennungsmotors für Kraftfahrzeuge, wobei zusammen mit einem Primärtreibstoff oder statt eines solchen Wasserstoff dem Verbrennungsraum direkt zugeführt wird.The invention relates to a method and a device for operating an internal combustion engine for motor vehicles, wherein the combustion chamber is fed directly together with a primary fuel or instead of such hydrogen.
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Verbrennungsmotors für Kraftfahrzeuge sowie eine Vorrichtung zur Durchführung des Verfahrens.The The invention relates to a method for operating an internal combustion engine for motor vehicles as well a device for carrying out of the procedure.
Aus
der
Eine derartige Anordnung ist aus strömungstechnischer Sicht ungünstig.A Such an arrangement is fluidic View unfavorable.
Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zu schaffen, das bzw. die eine verbesserte Einspeisung eines Zusatzbrennstoffes ermöglicht und andererseits den Wirkungsgrad des Verbrennungsmotors unter Berücksichtigung eines variablen Treibstoff Einsatzes verbessert.task the invention is to provide a method and a device the one or the improved feed of an additional fuel allows and On the other hand, the efficiency of the internal combustion engine under consideration a variable fuel use improved.
Hierzu wird erfindungsgemäß neben oder statt des Primärtreibstoffes ein zusätzlicher Treibstoff eingesetzt, und zwar Wasserstoff.For this is in accordance with the invention or instead of the primary fuel an additional one Fuel used, namely hydrogen.
Als Primärtreibstoff kommen hier Benzin oder Dieseltreibstoff in Frage.When primary fuel come here gasoline or diesel fuel in question.
Verglichen mit der relativ problemlosen Handhabung dieser Treibstoffe stellt der Einsatz von Wasserstoff sich erheblich problematischer dar.Compared with the relatively problem-free handling of these fuels the use of hydrogen is much more problematic.
Wesentlich ist dabei die hohe Flüchtigkeit des Wasserstoffgases, und zwar auch unter dem Gesichtspunkt der Mischungsmöglichkeit des flüssigen Treibstoffes mit Wasserstoff, wenn dieser beigemengt eingesetzt werden soll.Essential is the high volatility of the Hydrogen gas, and indeed from the point of view of the possibility of mixing of the liquid fuel with hydrogen, if this is added to be used.
Konstruktiv wichtig ist bei der Lösung dieser Probleme, dass ein Mehrfachventil in den Ansaugkanal eingesetzt ist. Vorzugsweise handelt es sich dabei um ein Doppelventil. Bei einem Doppelventil, also der Einspeisungsmöglichkeit von zwei Stoffen ergibt sich somit, dass einer dieser Stoffe – in diesem Fall der Primärtreibstoff – direkt in den Ansaugkanal zum Verbrennungsraum geführt wird, das Ventil ist somit mit einem Durchlass quasi Bestandteil des Ansaugkanals und wird als Hauptströmungskanal bezeichnetconstructive important in the solution These problems that a multiple valve used in the intake is. Preferably, this is a double valve. at a double valve, so the possibility of feeding two substances Thus it follows that one of these substances - in this case the primary fuel - is direct is guided into the intake passage to the combustion chamber, the valve is thus with a passage quasi part of the intake duct and is called Main flow channel designated
Das zweite Ventil mündet mit einem Nebenströmungskanal in diesen Ansaugkanal ein, wobei es von besonderer Bedeutung ist, dass die Einmündung im Wesentlichen tangential erfolgt.The second valve opens with a bypass duct into this intake channel, where it is of particular importance that the confluence in Essentially tangential occurs.
Durch spezielle Oberflächenkonstruktionen oder- formen sowie die Oberflächengüte, insbesondere der Innenwandung des Nebenströmungskanals, können die Einströmstrukturen und -formen beeinflusst und optimiert werden.By special surface constructions or shapes and the surface quality, in particular the inner wall of the bypass duct, the Einströmstrukturen and shapes are influenced and optimized.
Das Ventil kann nun sowohl als solches benutzt werden, d.h. bei einem Doppelventil zur Zuführung von zwei Treibstoffen dienen oder es kann wahlweise auch nur ein Treibstoff für den Antrieb des Verbrennungsmotors eingespeist werden.The Valve can now be used both as such, i. at a Double valve for feeding Serve of two fuels or it may optionally only one Fuel for be fed to the drive of the internal combustion engine.
Ein Treibstoff heißt in diesem Fall, für den Antrieb wird entweder der übliche Primärtreibstoff Benzin oder Diesel verwendet, oder aber, der Verbrennungsmotor wird zusätzlich mit Wasserstoff oder ausschließlich mit diesem angetrieben.One Fuel is called in this case, for the drive is either the usual Primary fuel gasoline or diesel used, or else, the internal combustion engine is additionally with Hydrogen or exclusively powered by this.
Durch die im Wesentlichen tangentiale Einspeisung des Wasserstoffs erfolgt eine sehr gute Vermischung mit dem Primärtreibstoff.By the substantially tangential feed of the hydrogen takes place a very good mixing with the primary fuel.
Wird andererseits an Stelle des üblichen Primärtreibstoffes nur Wasserstoff für die Verbrennung eingesetzt, so kann die Umstellung ebenfalls ohne Schwierigkeiten erfolgen, weil die Ventilanordnung unverändert bleibt und die tangentiale Zuführung des Wasserstoffgases strömungsmäßig optimal ist.Becomes on the other hand, instead of the usual primary fuel only hydrogen for the combustion used, the conversion can also without difficulty take place because the valve assembly remains unchanged and the tangential feed the hydrogen gas is optimally fluid is.
Die Zeichnung zeigt eine vereinfachte Darstellung eines als Adapter ausgebildeten Doppelventils.The Drawing shows a simplified representation of an adapter trained double valve.
