Abstract

Die Einlaßventile für die Luft und das Verbrennungsgas (H 2 ) des Rotationskolbenmotors werden vor einer Monogassäule vor dem Verbrennungsraum angeordnet. Separat zu jedem Reaktionspartner strömt das Gas nach den Ventilen monolog in einem kurzen Stück zum Verbrennungsraum und wird dort erst zu einem zündbaren Gemisch vereint. Dies führt dazu, daß die Ventile sich nur unwesentlich erwärmen und deshalb voll funktionsfähig bleiben. In den separaten Führungen kann das Monogas nicht zünden, da der Reaktionspartner nur bis zur Monogassäule vorhanden ist.The inlet valves for the air and the combustion gas (H 2) of the rotary piston engine are arranged in front of a monogas column in front of the combustion chamber. Separately to each reaction partner, the gas flows monologously in a short piece to the combustion chamber after the valves, where it is first combined to form an ignitable mixture. This means that the valves heat up only marginally and therefore remain fully functional. The monogas cannot ignite in the separate guides since the reactant is only available up to the monogas column.

Description

Die Erfindung betrifft einen Rotationskolbenmotor nach dem Oberbegriff des Patentanspruchs.The invention relates to a rotary piston engine according to the preamble of the claim.

Dieser Rotationskolbenmotor gemäß DE 43 43 165 A1 hat in der beschriebenen Version noch keine Einlaßventile. Die Gase H2 und Luft werden dort über eine koaxiale Leitung unmittelbar zum Verbrennungsraum geführt. Dies hat zur Folge, daß es zu einer kontinuierlichen Verbrennung des Gasgemischs kommt, mit einem nicht meßbaren Wirkungsgrad. Erst die nicht vorveröffentlichte DE 196 43 313 A1 hat Einlaßventile als Rückschlagventile eingeschlossen. Der Nachteil dieser Anordnung ist jedoch, daß die Ventile direkt und unmittelbar verbunden sind zum Brennraum des Motors. Das bewirkt, daß die Ventile sehr heiß werden und sich unter Umständen sogar verformen. Sie werden undicht und damit unbrauchbar.This rotary piston engine according to DE 43 43 165 A1 has in the described Version still no intake valves. The gases H2 and air are there via a coaxial line led directly to the combustion chamber. As a consequence, that there is a continuous combustion of the gas mixture with a not measurable efficiency. Only the unpublished DE 196 43 313 A1 has included intake valves as check valves. The disadvantage of this Arrangement is, however, that the valves are connected directly to the Engine combustion chamber. This causes the valves to become very hot and themselves may even deform. They become leaky and therefore unusable.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zu schaffen, bei der sich die Ventile nicht mehr übermäßig erwärmen.The invention has for its object to provide an arrangement in which the valves no longer overheat.

Zur Verbesserung der Standfestigkeit der Ventile wird vorgeschlagen, diese nun aus dem Bereich des Verbrennungsraumes 9 zu nehmen. Zwischen Ventil 13 und Verbrennungsraum 9 ist eine Gasführung 10 für ungemischten Wasserstoff (H2) und parallel dazu eine Leitung für Luft 8 angeordnet. Der ungemischte Wasserstoff kann nicht zünden. Erst im Verbrennungsraum 9 mischen sich die Gase und werden gezündet. So wird ein Erhitzen der Ventile verhindert.To improve the stability of the valves, it is proposed to take them out of the area of the combustion chamber 9 . A gas duct 10 for unmixed hydrogen (H 2 ) and a line for air 8 are arranged in parallel between valve 13 and combustion chamber 9 . The unmixed hydrogen cannot ignite. The gases only mix and are ignited in combustion chamber 9 . This prevents the valves from heating up.

Diese Ventilanordnung wird anhand des in der Figur gezeigten Ausführungs­ beispiels erläutert:This valve arrangement is based on the embodiment shown in the figure for example:

Die Ventile 13 sind nach außen in einen Flansch des Motorgehäuses 5 gelegt worden. Zwischen Ventil 13 und Verbrennungsraum 9 ist eine Gasführung 10 für das Monogas angeordnet.The valves 13 have been placed on the outside in a flange of the motor housing 5 . A gas duct 10 for the monogas is arranged between valve 13 and combustion chamber 9 .

Nachdem das Gas (H2 oder Luft) sein Ventil 13 verlassen hat, strömt es in je einer breiteren Gasführung 10 ohne den Reaktionspartner zum Verbrennungsraum 9. Erst im Verbrennungsraum 9 werden die Gase gemischt.After the gas (H 2 or air) has left its valve 13 , it flows in a wider gas duct 10 without the reaction partner to the combustion chamber 9 . The gases are only mixed in the combustion chamber 9 .

Eine ständig vorhandene Glühkerze 11 entzündet nun das Gemisch.A constantly present glow plug 11 now ignites the mixture.

Der Druck im Verbrennungsraum 9 steigt nun beträchtlich und treibt die auf den Achsen 3, 4 angeordneten Rotationskolben 1 und 2 in Drehrichtung an.The pressure in the combustion chamber 9 now rises considerably and drives the rotary pistons 1 and 2 arranged on the axes 3 , 4 in the direction of rotation.

Die Einlaßventile 13 schließen solange, bis der Druck im Verbrennungsraum 9 unter den Druck der Zuleitung 7 und 8 gesunken ist. The inlet valves 13 close until the pressure in the combustion chamber 9 has dropped below the pressure of the feed lines 7 and 8 .

Werden die Ventile 13 geöffnet, strömt zunächst Monogas in die dafür vorgesehenen Gasführung 10, welches sich erst im Verbrennungsraum 9 mischt und nur dort gezündet wird.If the valves 13 are opened, monogas first flows into the gas duct 10 provided for this purpose, which mixes only in the combustion chamber 9 and is ignited only there.

Die so erzeugte Monogassäule in der Gasführung 10 verhindert auf diese Art und Weise, daß sich die Ventile 13 übermäßig erwärmen. Über dem Gasgemisch befindet sich auf jeden Fall Gas ohne den Reaktionspartner, welches nicht zündet. Es wird sicher am Ende der Monogassäule ein Mischungsgrad existieren, der das Ende der Gasführung 10 etwas erwärmt. Dies ist aber in jedem Fall für die davon getrennten Ventile 13 ungefährlich, da die Gasführung 10 zusätzlich mit einer Wasserkühlung 12 versehen ist.The monogas column in the gas duct 10 thus produced prevents the valves 13 from heating up excessively. In any case, there is gas above the gas mixture without the reaction partner, which does not ignite. There will certainly be a degree of mixing at the end of the monogas column that warms the end of the gas duct 10 somewhat. In any case, however, this is harmless for the valves 13 separated therefrom, since the gas duct 10 is additionally provided with a water cooling 12 .
