 Bewegung des Kolbens einen Widerstand   R3   entgegen. Gelangt schliesslich der Kolben wieder an das Ende seines Hubes, dann wird das Auspuffventil durch seine   Bubscheibe   wie gewöhnlich geöffnet und gestattet, den in der Auspuffleitung enthaltenen Gasen den 
 EMI2.1 
 ist während des vierten Taktes T4, wird der Kolben durch keine Kraft gebremst. 



   Die Aufeinanderfolge der Erscheinungen, die soeben klargelegt worden sind, lassen 
 EMI2.2 
 die genannten Widerstände in drei Takten entstehen. Die Erfahrung zeigt, dass die Widerstandsarbeit einer in der beschriebenen Weise wirkenden Maschine bedeutend grösser ist als die Arbeit, welche die Maschine bei vollem Gange leistet. 



   Die Längsverschiebung der Steuerwelle für das   Auspuffventil,   die erforderlich ist, um die Hubdaumen A, B zur Wirkung. zu bringen, kann auf verschiedene Weise erreicht werden. 



    PATENT-ANSPRÜCHE :   
1. Verfahren zum Bremsen von Kraftwagen mittels der Antriebskraftmaschine, dadurch gekennzeichnet, dass die Verbindung mit dem Karburator unterbrochen und das Auspuffventil nicht nur während des Auspuffhubes, sondern auch am Ende des Ansaughubes und am Ende des Verdichtungshubes kurze Zeit geöffnet und sodann wieder geschlossen wird, so dass während des Ansaughubes ein teilweiser Unterdruck im Zylinder und dadurch ein Widerstand entsteht, hierauf am Ende des Ansaughubes der Zutritt toter Gase durch das Auspuffventil in den Zylinder ermöglicht ist, die während des Verdichtungshubes verdichtet werden, wodurch ein zweiter Widerstand erzeugt wird, worauf diese Gase am Ende des Verdichtungshubes   durch das AuspuSventil   austreten,

   so dass infolge des während des Expansionshubes wieder entstehenden teilweisen Unterdruckes ein dritter Widerstand hervorgerufen wird.

 Movement of the piston against a resistance R3. When the piston finally reaches the end of its stroke, the exhaust valve is opened as usual by its washer and the gases contained in the exhaust pipe are allowed to flow through
 EMI2.1
 if T4 is during the fourth cycle, the piston is not braked by any force.



   Let the sequence of the appearances that have just been made clear
 EMI2.2
 the mentioned resistances arise in three cycles. Experience shows that the resistance work of a machine operating in the manner described is significantly greater than the work that the machine does when it is running at full speed.



   The longitudinal displacement of the control shaft for the exhaust valve, which is necessary for the lifting thumbs A, B to take effect. Bringing can be accomplished in several ways.



    PATENT CLAIMS:
1. A method for braking motor vehicles by means of the prime mover, characterized in that the connection with the carburator is interrupted and the exhaust valve is opened for a short time and then closed again not only during the exhaust stroke, but also at the end of the intake stroke and at the end of the compression stroke, so that during the intake stroke a partial negative pressure arises in the cylinder and thus a resistance, then at the end of the intake stroke the entry of dead gases through the exhaust valve into the cylinder is made possible, which are compressed during the compression stroke, whereby a second resistance is generated, whereupon this Gases escape through the exhaust valve at the end of the compression stroke,

   so that a third resistance is created as a result of the partial negative pressure that occurs again during the expansion stroke.

Claims (1)

2. Einrichtung zur Durchführung des Verfahrens nach Anspruch l, dadurch gekennzeichnet, dass die Steuerwelle des Auspuffventils zwei das Auspuffventil am Ende des Ansauge-und Verdichtungshubes betätigende Hubdaumen (A, B) trägt und dass die Steuerwolle achsial verschiebbar angeordnet ist, um während der Bremsung zu dem gewöhnlichen Auspuffdaumen (c) noch die beiden Hubdaumen (A, B) in den Bereich der Hubspindel des Anspuffventiles bringen zu können. EMI2.3 2. Device for carrying out the method according to claim l, characterized in that the control shaft of the exhaust valve carries two lifting thumbs (A, B) which actuate the exhaust valve at the end of the intake and compression stroke and that the control wool is axially displaceable during braking In addition to the usual exhaust thumb (c), the two lifting thumbs (A, B) can be brought into the area of the lifting spindle of the start-up valve.
