Description
Gemischverdichtende Viertakt-Brennkraftmaschine Die Erfindung betrifft eine gemischverdichtende Viertakt-Brennkraftmaschine mit einem Wärmespeicher, in dem ein am Ende des Verdichtungshubes zur Entzündung der Ladung dienender Teil der Verbrennungsgase aufgespeichert wird.Mixture-compressing four-stroke internal combustion engine The invention relates to a mixture-compressing four-stroke internal combustion engine with a heat accumulator, in the one used to ignite the charge at the end of the compression stroke Combustion gases is stored.
In den bekannten Wärmespeichern solcher Brennkraftmaschinen sind zur Regelung der Strömung der aufgespeicherten Verbrennungsgase zwangsläufig gesteuerte Ventile vorgesehen. Infolge dieser zwangsläufigen Steuerungen werden die Herstellungskosten, Antriebskraft sowie der Materialverschleiß derart erhöht, daß die Wirtschaftlichkeit eines Wärmespeichers an Brennkraftmaschinen in Frage gestellt ist.In the known heat accumulators of such internal combustion engines are for Regulation of the flow of the accumulated combustion gases inevitably controlled Valves provided. As a result of these inevitable controls, the production costs, Driving force and material wear are increased in such a way that the economy a heat accumulator on internal combustion engines is in question.
Die genannten Nachteile werden gemäß der Erfindung dadurch behoben, daß in dem zum Speicher führenden Kanal ein an seiner Sitzfläche mit Rillen o. dgl. versehenes Rückschlagventil vorgesehen ist und dieses Rückschlagventil den Druck der in dem Wärmespeicher aufgespeicherten Verbrennungsgasmenge bei abnehmendem Druck im Zylinderraum gleichfalls, und zwar mindestens bis unter den Enddruck der Verdichtung, verringern kann, so daß das Rückschlagventil von der verdichteten Ladung geöffnet und diese mit dem heißen Gasrest in Verbindung gesetzt wird.The disadvantages mentioned are eliminated according to the invention by that in the channel leading to the memory a on its seat with grooves o. provided check valve is provided and this check valve the pressure the amount of combustion gas stored in the heat accumulator with decreasing pressure in the cylinder chamber as well, at least up to below the final pressure of compression, can decrease so that the check valve is opened by the compressed cargo and this is brought into contact with the hot gas residue.
Des weiteren ist die Brennkraftmaschine so ausgestaltet, daß der Hub des Rückschlagventils geändert werden kann.Furthermore, the internal combustion engine is designed so that the stroke of the check valve can be changed.
Eine beispielsweise Ausführungsform der Erfindung ist durch einen Längsschnitt in der beiliegenden Zeichnung dargestellt.An example embodiment of the invention is through a Longitudinal section shown in the accompanying drawing.
Ein vermittels seines unteren Gewindes an einer gemischverdichtenden Brennkraftmaschine aufschraubbares Gehäuse G besitzt in seinem Inneren einen zur Aufnahme heißer Verbrennungsgase dienenden Speicherraum A, der durch einen Kanal D mit dem Zylinderraum verbunden ist. Dieser Kanal D wird durch ein an seiner Sitzfläche mit Rillen o. dgl. versehenes Rückschlagventil R geöffnet bzw. geschlossen, welches seine Führung durch drei oder mehrere Polarme P sowie durch einen FührungszapfenF o. dgl. erhält. Der Führungszapfen ist beweglich in einer Elektrode E angeordnet, welche in einer den Speicherraum A nach außen ab- . schließenden Verschlußschraube M isoliert sowie vermittels Gewinde o. dgl. verstellbar befestigt ist.One by means of its lower thread on a mixture-compressing one Internal combustion engine screw-on housing G has in its interior a for Receiving hot combustion gases serving storage space A, which is through a channel D is connected to the cylinder space. This channel D is through a on its seat Check valve R provided with grooves or the like is opened or closed, which its guidance by three or more polar arms P and by a guide pin F. o. The like. Receives. The guide pin is movably arranged in an electrode E, which in one of the storage space A to the outside. closing screw plug M is insulated and adjustable by means of a thread or the like.
Infolge der Anordnung und Ausgestaltung des Rückschlagventils R nimmt der Druck der in dem Wärmespeicher A aufgespeicherten Verbrennungsgasmenge bei abnehmendem Zylinderdruck im Zylinderraum gleichfalls ab, und zwar mindestens bis unter den Enddruck der Verdichtung. Hierdurch wird erreicht, daß das Rückschlagventil R von der verdichteten Ladung geöffnet und diese in Verbindung mit dem heißen Gasrest gesetzt wird.As a result of the arrangement and configuration of the check valve R increases the pressure of the amount of combustion gas stored in the heat accumulator A with decreasing The cylinder pressure in the cylinder space also decreases, at least to below the Final pressure of compression. This ensures that the check valve R of the compressed charge opened and this in connection with the hot gas residue is set.
Zur Regelung der Spät- bzw. Frühzündungen kann der Hub des Rückschlagventils R geändert werden.The stroke of the check valve can be used to regulate the late or early ignition R can be changed.
