Description
Selbstzündende Verbrennungskraftmaschine. Gegenstand der Erfindung ist eine selbst zündende Verbrennungskraftmaschine, wel ehe sieh dadurch auszeichnet, dass ein Teil der den Kompressionsraum des Zylinders bildenden Wandung zur Veränderung des Kompressionsraumes und des Kompressions druckes verstellbar ist. Bei einer derart ein berichteten Maschine lässt sich demnach zum Beispiel beim Anlassen der Kompressions raum verringern und somit der Kompressions druck entsprechend erhöhen, so dass man selbst bei Verwendung von gröbsten Roh ölen unter Verzicht jedweder besonderen Zündvorrichtung vom kalten Zustande aus eine Selbstzündung herbeiführen kann. Auch im Betriebe kann der Kompressionsraum derart eingestellt werden, dass Frühzündun gen infolge zu starker Erwärmung vermieden werden.
Der bewegliche Wandungsteil wird zweck mässig durch einen in den Zylinder eingesetz ten Gegenkolben gebildet, der mittelst einer in einem Zylinderdeckel geführten Schrau benspindel im Zylinder achsial verstellbar ist. .
Die beiliegende Zeichnung zeigt ein Aus führungsbeispiel des Erfindungsgegenstan- des, wovon Fig. 1 einen Vertikalschnitt, Fig. 2 einen dazu senkrechten Vertikalteil schnitt und Fig. 3 einen Horizontalschnitt nach der Linie a-b in Fig. 1 darstellt. Im Arbeitszylinder 1 des gezeichneten stehenden Explosionsmotors ist der Arbeits kolben 2 verschiebbar.
Der Zylinder 1 weist im untern Teil zwei vertikale, im Kurbel gehäuse 15 mündende Längskanäle 4 auf, die von zwei Ausnehmungen ä am Kolben 2 in seiner untern Totpunktlage freigelegt wer den. Überdies besitzt der Zylinder 1 zwei Schlitze 5 zur Zufuhr von Brennstoffluft gemisch, das durch Stutzen 6 den Schlitzen 5 zuströmt. Die Verbrennungsgase werden durch die Schlitze 7 und die Stutzen 8 des Zylinders abgeführt. Im Oberteil des Zylin ders 1 ist ein Gegenkolben 10 untergebracht, der mittelst einer im Zylinderdeckel 9 ge führten Schraubenspindel 11 im Zylinder 1 achsial verstellbar ist, beim normalen Be triebe aber unbeweglich ist.
Zum Anlassen wird der Gegenkolben 10 mittelst der Spindel 11 im Zylinder 1 in seine tiefste Stellung verschoben, um den Kom pressionsraum im Zylinder zu verringern. Für den Betrieb wird der Gegenkolben 10 wieder in normale Stellung zurückgeführt.
Beim Arbeiten komprimiert der hoch gehende Kolben 2 die über ihm befindliche Ladung bis zur Selbstzündung, während er gleichzeitig unter ihm ein Vakuum schafft, zufolge dessen schliesslich Brennstoffluft gemisch durch die Schlitze 5 in den Zylinder raum unter dem Kolben und in das Kurbel gehäuse 15 eingesaugt wird.
Beim darauf folgenden Niedergehen des Kolbens 2, das durch den Druck der Verbrennungsgase be wirkt wird, kommen dieselben schliesslich durch die Schlitze 7 zum Auspuff, während die frische Ladung durch die Zylinderkanäle 4 und die Kolbenausnehmungen 3 in zwei getrennten kompakten Strömen, die mit den abziehenden Verbrenungsgasen keine Mi schung eingehen, in den Zylinder eingeblasen wird, um nachher komprimiert zu werden. Im normalen Betrieb bleibt der Gegenkolben 10 unbeweglich.
Soll aus irgend einem Grund der Kompressionsdruck im Zylinder während des Betriebes geändert werden, so genügt es, den Gegenkolben 10 im Zylinder mittelst der Schraubenspindel 11 höher oder tiefer zu stellen.
Self-igniting internal combustion engine. The invention relates to a self-igniting internal combustion engine, which is characterized in that part of the wall forming the compression chamber of the cylinder can be adjusted to change the compression chamber and the compression pressure. With such a reported machine, for example, the compression space can be reduced when starting and thus the compression pressure increased accordingly, so that even when using the coarsest crude oils, self-ignition can be caused from a cold state without any special ignition device. The compression chamber can also be set in operation in such a way that premature ignition due to excessive heating is avoided.
The movable wall part is expediently formed by an opposing piston inserted into the cylinder, which is axially adjustable in the cylinder by means of a screw guided in a cylinder cover. .
The accompanying drawing shows an exemplary embodiment of the subject matter of the invention, of which FIG. 1 is a vertical section, FIG. 2 is a vertical section perpendicular thereto and FIG. 3 is a horizontal section along the line a-b in FIG. In the working cylinder 1 of the drawn standing explosion engine, the working piston 2 is displaceable.
The cylinder 1 has in the lower part two vertical, in the crank housing 15 opening longitudinal channels 4, which exposed by two recesses ä on the piston 2 in its bottom dead center who the. In addition, the cylinder 1 has two slots 5 for the supply of fuel-air mixture, which flows through the nozzle 6 to the slots 5. The combustion gases are discharged through the slots 7 and the nozzle 8 of the cylinder. In the upper part of the cylinder 1 a counter piston 10 is housed, which is axially adjustable by means of a ge in the cylinder cover 9 guided screw spindle 11 in the cylinder 1, but is immobile in normal loading operations.
To start the opposed piston 10 is moved by means of the spindle 11 in the cylinder 1 to its lowest position in order to reduce the compression space in the cylinder. For operation, the opposing piston 10 is returned to its normal position.
When working, the rising piston 2 compresses the charge above it until it spontaneously ignites, while at the same time it creates a vacuum under it, according to which the fuel-air mixture is finally sucked in through the slots 5 in the cylinder space under the piston and in the crankcase 15 .
When the piston 2 subsequently descends, which is acted upon by the pressure of the combustion gases, the same finally come through the slots 7 to the exhaust, while the fresh charge flows through the cylinder ducts 4 and the piston recesses 3 in two separate compact flows, which with the withdrawing Combustion gases do not enter into a mixture, is blown into the cylinder to be compressed afterwards. In normal operation, the opposing piston 10 remains immobile.
If, for whatever reason, the compression pressure in the cylinder is to be changed during operation, it is sufficient to set the opposing piston 10 in the cylinder higher or lower by means of the screw spindle 11.
