Von der in Fig. 6 dargestellten Stellung, die der höchsten Kompression entspricht, bewegen sich die beiden Kolben nach der gleichen Richtung. Die Maximalwirkung der Explosionsmischung erfolgt dann, wenn die Kolben die in Fig. 7 angedeutete Stellung einnehmen. In dieser Stellung bietet die Kurbel 30 der von der Explosion herrührenden Kraft den grössten Hebelarm dar, wodurch das Drehmoment der Welle gross ist.

   In diesem Zeitpunkte bewegt sich der innere Kolben mit beträchtlich geringerer Geschwindigkeit als der äussere Kolben, so dass er für eine ganz kurze Zeit gewissermassen ein ortsfestes Widerlager bildet, gegen das die Explosion wirkt ; deshalb wird der äussere   Kolben 23,   der gerade dann mit der Kurbel in der längsten Hebelarmstellung verbunden ist, mit grosser Geschwindigkeit nach aufwärts getrieben. Wären die beiden Kurbeln 29 und 30 gleich lang, so besässe (Fig. 7) die Kurbel 30 eine viel grössere Umfangsgeschwindigkeit als die den Totpunkt durchlaufende Kurbel 29. Dadurch würde ein grösserer Abstand zwischen den beiden Kolben gebildet werden und die Kompression nicht so günstig ausfallen. 



   Der wirksamste Teil der von der Explosion   herrührenden   Energie wirkt auf die Kurbeln in den

Der von den Kolben zwischen diesen Endstellungen begrenzte Weg ist etwas grösser als die Hälfte des einer halben Wellenumdrehung entsprechenden Kolbenhubes. Während die Explosion im Zylinder stattfindet, ist die Offnung 40 von dem inneren   Kolben 24   überdeckt, so dass die Energie der Explosion nicht auf die Ein-oder   Auslassventile   einwirkt. Die Öffnung 40 wird erst freigegeben, nachdem ein grosser Teil der Energie

From the position shown in Fig. 6, which corresponds to the highest compression, the two pistons move in the same direction. The maximum effect of the explosion mixture takes place when the pistons assume the position indicated in FIG. 7. In this position, the crank 30 provides the greatest lever arm for the force resulting from the explosion, whereby the torque of the shaft is high.

   At this point in time the inner piston moves at a considerably slower speed than the outer piston, so that for a very short time it forms a fixed abutment against which the explosion acts; therefore the outer piston 23, which is then connected to the crank in the longest lever arm position, is driven upwards at great speed. If the two cranks 29 and 30 were of the same length, then (FIG. 7) the crank 30 would have a much greater circumferential speed than the crank 29 passing through dead center. This would result in a greater distance between the two pistons and the compression would not be so favorable .



   The most effective part of the energy from the explosion acts on the cranks in the

 FIG. 7 advances to the horizontal position according to FIG. The path limited by the piston between these end positions is somewhat greater than half of the piston stroke corresponding to half a shaft revolution. While the explosion is taking place in the cylinder, the opening 40 is covered by the inner piston 24 so that the energy of the explosion does not act on the inlet or outlet valves. The opening 40 is only released after a large part of the energy

 is only due to the different lengths of the two cranks. In Fig. 9, the shorter crank has reached the point, while the longer crank 29 represents the largest lever arm.
