    Zweitaktverbrennungskraftmaschine mit durch den Arbeitskolben gesteuerten Lade-und Auspuffschlitzen.   



   Zweitaktverbrennungskraftmaschinen mit durch den Arbeitskolben gesteuertem Lade-und   Auspuffschtitzen besitzen   im allgemeinen Ablenker für die am Ende des Arbeitshubes eintretende frische Ladung, die von einem lediglich vor den Ladeschlitzen angeordneten besonderen Fortsatz des Kolbenbodens oder einer Ausnchnung des Kolbens gebildet werden. Dient nun statt diesen 
 EMI1.1 
 als Ablenker, dann wird die aus den seitlichen Schlitzen austretende Ladung nur ungenügend oder überhaupt nicht mehr nach dem Arbeitsraum des Zylinders abgelenkt, sie   fliesst   vielmehr unmittelbar um den Stufenfortsatz herum zum Auspuffkanal. 



     Gemäss   der Erfindung erreicht man nun auch bei den Maschinen der letzteren Art eine gute Ablenkung der aus den scitlichen Schlitzen in den   Zylindf'rr & um eintretenden Ladung dadurch,   dass man den oder die mittleren Ladeschlitze länger ausbildet als die seitlichen. Es legt dann der Kolben beim   Arbeitahube   zuerst die nuttleren Schlitze frei, wodurch infolge der   Ablt'nkerwirk1Ulg   des Fortsatzes eine nach dem Zylinderinneren bzw. deckel gerichtete geschlossene Strömung entsteht. Diese Strömung bleibt bei der weiteren Kolbenbewegung bestehen und reisst bei der Frei-   legung der seitlichen Schütze die   durch diese messende Ladung mit nach dem Zylinderinneren. 



   Die Zeichnung zeigt den   Gegenstand   der Erfindung in beispielsweiser Ausführung in Fig.   l

   Zündkammer   c in Verbindung steht, in die Brennstoff durch die Düse d eingespritzt wird. Der Auspuff der   Abgase erfolgt durch die Schlitze c, denen   gegenüber drei Ladeschlitze f angeordnet sind. Der mittlere dieser S litze ist länger ausgebildet, so dass er von der steuernden Kante 9 des Kolbens   freigelegt wird   als die seitlichen Schlitze. Der Kolbenboden läuft unter Bildung

    Two-stroke internal combustion engine with loading and exhaust ports controlled by the working piston.



   Two-stroke internal combustion engines with loading and exhaust ports controlled by the working piston generally have deflectors for the fresh charge entering at the end of the working stroke, which are formed by a special extension of the piston crown or a recess in the piston arranged only in front of the loading slots. Now serve instead of these
 EMI1.1
 as a deflector, then the charge emerging from the lateral slots is only inadequately or not at all deflected to the working space of the cylinder, rather it flows directly around the step extension to the exhaust duct.



     According to the invention, even with the machines of the latter type, a good deflection of the load entering the cylinder from the slits is achieved by making the middle loading slot or slots longer than the lateral ones. The piston then first exposes the nuttler slits at the working cover, which creates a closed flow directed towards the cylinder interior or cover due to the deflecting effect of the extension. This flow persists as the piston continues to move and, when the side gates are exposed, carries the charge measured by this with it to the inside of the cylinder.



   The drawing shows the subject matter of the invention in an exemplary embodiment in FIG
 EMI1.2
   Ignition chamber c communicates into which fuel is injected through the nozzle d. The exhaust of the exhaust gases takes place through the slots c, opposite which three loading slots f are arranged. The middle of these S litz is made longer so that it is exposed by the controlling edge 9 of the piston than the lateral slots. The piston crown runs under formation
 EMI1.3
