EMI1.1
Die Erfindung betrifft eine Viertaktverbrennungskraftmaschine mit Kurbelkastenpumpe und die Zylinderein-und-auslässe steuerndem Kolben und bezweckt, die Arbeitsweise im Viertakt unter Verwendung nur eines einzigen gesteuerten Ventiles zu ermöglichen.
Die Zeichnung zeigt die Maschine schematisch im Schnitt bei verschiedenen Kolbenstelhmgen.
Bewegt sich der Kolben K im Zylinder E aufwärts (Fig. 1), so wird durch den Unterdruck, der dadurch im Kurbelgehäuse entsteht, das Gasgemisch durch den Einsaugstutzen A und den Kanal C in das Kurbelgehäuse D eingesaugt.
Das Ventil B ist während des Aufwärtsganges des Kolbens J offen. Es wird durch die Nocke N gesteuert. Infolge des Übersetzungsverhältnisses der Zahnräder R1 und R2 (1:2) macht die Nocke halb so viel Umdrehungen als die Kurbelwelle.
Ist der Kolben K im oberen Totpunkte angelangt, so wird das Ventil B geschlossen (Fig. dz Beim Abwärtsgang des Kolbens wird das Gemisch im Kurbelgehäuse verdichtet. Kurz vor dem unteren Totpunkte gibt der Kolben im Zylinder einen Schlitz frei, und das Gemisch strömt, vom Kurbelgehäuse durch den Uberströmkanal C* in den Zylinder. Das Ventil B ist dabei geschlossen (Fig. 3).
Beim Aufwärtsgang. des Kolbens wird das Gemisch im Zylinder verdichtet. Hat der Kolben den oberen Totpunkt erreicht, so wird das Gemisch durch einen Funken der Zündkerze Z zur Explosion gebracht (Fig. 4). Dadurch wird der Kolben nach unten getrieben (Arbeitshub). Bevor der Kolben seine tiefste Lage erreicht, gibt er in der Zylinderwand wieder einen Schlitz frei und die Verbrennung- gase entweichen durch den Kanal F (Fig. 5). Darauf folgt wieder das Ansaugen im Kurbelkasten, wobei das Ventil B geöffnet ist (Fig. 1) usw.
Das Schliessen und Öffnen der Schlitze besorgt der Kolben K. - Infolge des gesteuerten Ventils kann die Maschine nur nach jeder zweiten Umdrehung saugen..

EMI1.1
The invention relates to a four-stroke internal combustion engine with a crankcase pump and a piston controlling the cylinder inlets and outlets, and aims to enable the four-stroke mode of operation using only a single controlled valve.
The drawing shows the machine schematically in section with different piston lengths.
If the piston K moves upwards in the cylinder E (FIG. 1), the gas mixture is sucked into the crankcase D through the intake port A and the channel C due to the negative pressure that is created in the crankcase.
Valve B is open during piston J upward travel. It is controlled by the N cam. As a result of the gear ratio of the gears R1 and R2 (1: 2), the cam makes half as many revolutions as the crankshaft.
When piston K has reached top dead center, valve B is closed (Fig. Dz. When the piston moves downwards, the mixture in the crankcase is compressed. Shortly before bottom dead center, the piston opens a slot in the cylinder and the mixture flows from Crankcase through the overflow channel C * into the cylinder, valve B being closed (Fig. 3).
When going up. the piston compresses the mixture in the cylinder. When the piston has reached top dead center, the mixture is caused to explode by a spark from the spark plug Z (FIG. 4). This drives the piston down (working stroke). Before the piston reaches its lowest position, it clears a slot in the cylinder wall and the combustion gases escape through channel F (Fig. 5). This is followed by suction in the crankcase again, with valve B open (Fig. 1), etc.
The closing and opening of the slots is done by piston K. - As a result of the controlled valve, the machine can only suck after every second rotation.
