Description

Einspritzbrennkraftmaschine Die Erfindung bezieht sich auf eine Einspritzbrennkraftmaschine, bei der am Ende des Verdichtungshubes die gesamte Verbrennungsluft sich in einer im Kolbenboden angeordneten unterteilten, mit dem Hubraum in offener Verbindung stehenden Verbrennungskammer befindet und bei der der Brennstoff gegen Ende des Verdichtungshubes in diese Verbrennungskammer eingespritzt wird. Gemäß der Erfindung sind die Brennkammerteile durch einen oder mehrere tangential gerichtete Kanäle miteinander verbunden, und der Brennstoff wird nur in einen Teil der Brennkammer eingespritzt, aus dem dann ein Teil des Brennstoff-Luft-Gemisches durch die bei -der Verbrennung erzeugte Drucksteigerung in den anderen Brennkammerteil eingeblasen wird, wobei er eine Drehbewegung des Inhaltes dieses Brennkammerteiles bewirkt.Injection internal combustion engine The invention relates to an injection internal combustion engine, in which at the end of the compression stroke all of the combustion air is in one subdivided, arranged in the piston crown, in open connection with the displacement standing combustion chamber and with the fuel towards the end of the Compression stroke is injected into this combustion chamber. According to the invention are the combustion chamber parts through one or more tangentially directed channels interconnected, and the fuel is only in part of the combustion chamber injected, from which then part of the fuel-air mixture through the at - The pressure increase generated by the combustion is blown into the other part of the combustion chamber is, causing a rotary movement of the contents of this combustion chamber part.

In der Zeichnung sind einige Ausführungsbeispiele der Erfindung dargestellt.Some exemplary embodiments of the invention are shown in the drawing.

Fig. r zeigt eine Draufsicht auf den Kolben und Fig. 2 einen Längsschnitt durch den Kolben und die angrenzenden Maschinenteile. Dabei sind vier Brennkammerteile a1, a2, b1 und b2 vorhanden, die durch tangential gerichtete Kanäle miteinander verbunden sind. Der Brennstoff wird durch die Düse c in die Brennkammerteile a1 und a2 eingespritzt. Die dadurch in diesen Räumen eingeleitete Verbrennung erzeugt einen Überdruck, der einen Teil des Brennstoff-Luft-Gemisches aus. diesen Räumen in die Brennkammerteile bi und b2 einbläst, in denen es weiter verbrennt. Da die Verbindungskanäle der Brennkammerteile tangential gerichtet sind, so wird durch das in die Brennkammerteile b1 und b2 eingeblasene Brennstoff-Luft-Gemisch der Inhalt dieser Brennkammerteile in Drehbewegung versetzt.FIG. R shows a plan view of the piston and FIG. 2 shows a longitudinal section through the piston and the adjacent machine parts. There are four combustion chamber parts a1, a2, b1 and b2 are present, which are connected to one another by tangentially directed channels are connected. The fuel is through the nozzle c into the combustion chamber parts a1 and a2 injected. The resulting combustion generated in these rooms an overpressure that makes up part of the fuel-air mixture. these rooms blows into the combustion chamber parts bi and b2, in which it continues to burn. Since the Connecting channels of the combustion chamber parts are directed tangentially, so is through the fuel-air mixture blown into the combustion chamber parts b1 and b2 is the content this combustion chamber parts are set in rotary motion.

In den Brennkammerteilen a1 und a2, in die der Brennstoff eingespritzt wird, ist nur ein Teil der für die gesamte eingespritzte Brennstoffmenge zur Verfügung stehenden Luft enthalten. Die in diesen Brennkammerteilen einsetzende Verbrennung erfolgt daher zunächst unter Luftmangel, so daß hohe Drücke beim Einsetzen der Verbrennung vermieden werden. - Die in den anderen Brennkammerteilen b1 und b2 befindliche Luft wird erst dann mit zur Verbrennung herangezogen, wenn durch die in den Brennkammerteilen at und a2 eingeleitete Verbrennung ein überdruck erzeugt wird, der einen Teil des Brennstoff-Luft-Gemisches aus dem ersten in den zweiten Brennkammerteil einbläst. Beim Abwärtsgang des Kolbens wird der Spalt zwischen dem Zylinderdeckel und den Trennwänden zwischen den einzelnen Brennkammerteilen größer, so daß die einzelnen Brennkammerteile mehr und mehr eine gemeinsame Brennkammer bilden. Dadurch wird bewirkt, daß der gesamte Luftinhalt aller Brennkammerteile zür-=restlo.sen Verbrennung des Brennstoffes herangezogen und die irl, den Brennkammerteilen .b1 und b2 hervorg,4n rufene Wirbelbildung auf die gesamten Bre.*,` kammern ausgedehnt wird.In the combustion chamber parts a1 and a2, into which the fuel is injected only part of the fuel is available for the total amount of fuel injected contain stagnant air. The combustion that begins in these parts of the combustion chamber is therefore initially carried out with a lack of air, so that high pressures at the onset of combustion be avoided. - The air in the other combustion chamber parts b1 and b2 is only then used for the combustion if by the in the combustion chamber parts at and a2 initiated combustion creates an overpressure which is part of the Injects fuel-air mixture from the first into the second part of the combustion chamber. When the piston goes down, the gap between the cylinder cover and the Partition walls between the individual combustion chamber parts larger, so that the individual Combustion chamber parts form more and more a common combustion chamber. This will causes that the entire air content of all combustion chamber parts for = restless combustion of the Fuel used and the irl, the combustion chamber parts .b1 and b2 emerge, 4n called vortex formation to the entire Bre. *, `chambers is extended.

Auf diese Weise wird bei verzögert ein-,, setzender Verbrennung und daher unter Vermeidung unzulässig hoher Beanspruchung des Triebwerkes eine vollkommene Verbrennung ermöglicht, ohne daß hierfür besondere Zündkammern oder Luftspeicher erforderlich sind.In this way, if the onset of combustion is delayed, and therefore, while avoiding inadmissibly high stress on the engine, a perfect one Combustion is made possible without the need for special ignition chambers or air storage required are.

Bei der Ausführungsform nach Fig.3 sind nur zwei Brennkammerteile a und b vorhanden. Fig.4 und 5 zeigen zwei Ausführungsformen mit einem Brennkammerteil a, in den der Brennstoff gespritzt wird, und zwei Brennkammerteilen b1, b2. Nach Fig.6 -wird der Brennkammerteil a, in den der Brennstoff gespritzt wird, von einem ringförmigen Brennkammerteil b umschlossen.In the embodiment according to Figure 3 there are only two combustion chamber parts a and b available. 4 and 5 show two embodiments with a combustion chamber part a, into which the fuel is injected, and two combustion chamber parts b1, b2. To Fig.6 - the combustion chamber part a, into which the fuel is injected, is of a enclosed annular combustion chamber part b.
