Description
Die Erfindung bezieht sich auf eine Gemischbildungseinrichtung für einen Einspritzschiebermotor mit neuartiger Anordnung der Einspritzdüse und Verwendung von Leitschaufeln im Ansaugkanal.The invention relates to a mixture formation device for a slide valve engine with a novel arrangement of the injection nozzle and use of guide vanes in the intake duct.
Die direkte Einspritzung des Brennstoffes in den Verbrennungsraum ist bekannt. Auch die Anordnung von Leitzungen u. dgl. in mit Ventilen gesteuerten Motoren ist bereits bekannt.The direct injection of fuel into the combustion chamber is known. The arrangement of guide tongues and the like in valves controlled Motors is already known.
Es ist ferner auch schon vorgeschlagen worden, bei durch Ventile gesteuerten :@Zotoren Vergaser mit Luftzerstäubung des Brennstoffes durch in Nähe des Saugventils angeordnete Düsen zu verwenden.It has also already been proposed for valves controlled : @Zotoren carburetor with air atomization of the fuel by near the suction valve to use arranged nozzles.
Die Erfindung bringt durch die neuartige Anordnung an sich bekannter Elemente verschiedene -%vesentliche«#?orteile. Durch das immittelbare Einspritzen des Brennstoffes in die in der gleichen Richtung einströmende Verbrennungsluft wird eine außerordentlich gute Zerstäubung des Brennstoffes- und eine günstige Vermischung von Brennstoff und Verbrennungsluft erreicht. Diese vorteilhafte Brennstoffverteilung bewirkt, daß jedem Brennstoffteilchen der zur Verbrennung nötige Sauerstoff zugeführt wird und daß dadurch der Brennstoffverbrauch in Vergleich zu den bisherigen Verfahren fällt.Due to the novel arrangement, the invention is known per se Elements various -% essential «#? Advantages. Through immediate injection of the fuel in the combustion air flowing in in the same direction an extremely good atomization of the fuel and a favorable mixing achieved by fuel and combustion air. This advantageous fuel distribution causes each fuel particle to be supplied with the oxygen necessary for combustion and that this reduces the fuel consumption compared to the previous method falls.
Die empfindliche Einspritzdüse ragt in die v orbeiströmende Ansaugluft hinein und wird dadurch gut gekühlt. Die Brennstoffdüse ist von außen eingeführt und kann deshalb leicht herausgenommen, gewartet oder ersetzt werden. Bei luftgekühlten Zylindern ist noch von Wichtigkeit, daß die Anordnung der Düsen am Ansaugrohr die Kühlfläche des Zylinders nicht wie bisher einschränkt.The sensitive injection nozzle protrudes into the intake air flowing by inside and is therefore well cooled. The fuel nozzle is inserted from the outside and can therefore be easily removed, serviced or replaced. With air-cooled Cylinders is also important that the arrangement of the nozzles on the intake pipe the The cooling surface of the cylinder is not restricted as before.
Durch den Einbau einer Leitschaufel unmittelbar vor der Einlaßöffnung wird den einströmenden Gasen eine bestimmte Richtung gegeben, und es bildet sich ein ständig gleichmäßiger, weitgehend vom jeweiligen Betriebszustand unabhängiger Wirbel entlang der Schieberwand. Die Zündwelle des Gasgemisches breitet sich hierdurch bei jedem Arbeitshub in gleicher Weise aus, so daß ein regelmäßiger und ruhiger Lauf des Motors erzielt wird.By installing a guide vane immediately in front of the inlet opening the inflowing gases are given a certain direction, and it is formed a steady, largely independent of the current operating status Vortex along the valve wall. The ignition wave of the gas mixture spreads through this in the same way with every working stroke, so that a regular and quieter Running of the engine is achieved.
Durch das Entlangstreichen des Gemisches an der heißen Schieberwand erwärmen sich die Brennstoffteilchen und werden so fast restlos in dampfförmigen Zustand übergeführt.By brushing the mixture along the hot slide wall the fuel particles heat up and become almost completely in vapor form State transferred.
Die Abbildung stellt den Schieber i. den Zylinder a und den Ansaugstutzen 3 im Schnitt dar. Im Ansaugstutzen 3 sind die Leitschaufel. und die Brennstoffeinspritzdüse @ eingebaut.The figure represents the slide i. the cylinder a and the intake manifold 3 in section. In the intake 3 are the guide vanes. and the fuel injector @ built-in.
Der Schieber i öffnet in der Pfeilrichtung. Die Luft strömt durch den Einspritzstrahl hindurch und reichert sich mit Brennstoff an. Nachdem dem Gemisch von der Leitschaufel die gewünschte Richtung erteilt ist, strömt es, insbesondere wenn mehrere gleiche Einlaßdüsen am Zylinderumfang angeordnet sind. in gleichmäßigem Wirbel entlang der Zylinderwand.The slide i opens in the direction of the arrow. The air flows through passes through the injection stream and becomes enriched with fuel. After the mixture is given the desired direction by the guide vane, it flows, in particular if several identical inlet nozzles are arranged on the cylinder circumference. in even Vortex along the cylinder wall.
