Description
Claims (1)
- Patentanspruch;Zweitaktbrennkraftmaschine, bestehend aus einem Motorblock mit einer Zylinderbohrung und einer Kurbelkammer, einem in der Zyünderbohrung eine Brennkammer begrenzenden, hin- und herbeweglichen Kolben, einem in die Kurbelkammer mündenden Ansaugkanal mit Gemischbildungsvorrichtung, einem in der Brennkammerwand beginnenden Auslaßkanal und einem die Kurbelkammer mit to der Brennkammer verbindenden Überströmkanalsystem, das aus einem sich in die Kurbelkammer öffnenden, relativ langen Kanalabschnitt engen Querschnitts, dem auf wenigstens einem Teilabschnitt in bestimmten Betriebsbedingungen ein vergleichsweise kurzer Nebenschlußkanal parallelgeschaltet ist, und einem sich daran anschließenden, in die Brennkammer öffnenden, relativ kurzen Kanalabschnitt weiten Querschnitts besteht und ein Ventil enthält, das lastabhängig im Sinne einer die wirksame Lä«ge des Überströmkanalsystems bei hoher Maschinenbelastung verkürzenden Weise steuerbar ist und dabei den freien Strömungsquerschnitt des Nebenschlußkanals verändert, dadurch gekennzeichnet, daß sich das Ventil (34; 65a, 65b) nur in dem Nebenschlußkanal (42,33; 20a,20i>;befindet.
