Abstract

Um eine Zweitakt-Brennkraftmaschine mit einem Vergaser mit einem Vergasungsteil (Venturi) (12), einem dem Verga­ sungsteil vorgeschalteten Ansaugteil (13), einem Drossel­ klappenteil (14), einem dem Drosselklappenteil nachgeschal­ teten Ausgangskanal (15), einer Haupt- und einer Teillast­ düsenkammer (16) und einer druckbeaufschlagbaren Kraftstoff­ zuführungsleitung, einem auf einer Kurbelkammer (34) angeord­ neten Zylinder (30) mit einem Einlaßkanal mit einem Einlaß­ schlitz (22), wobei der im Ansaugflansch (20) ausgebildete Ein­ laßkanal mit dem Ausgangskanal des Vergasers verbunden ist, so weiterzubilden, daß eine Leerlaufstabilisierung erreicht werden kann, ist vorgesehen, daß der Kurbel­ kammer (34) Kraftstoff-Luft-Gemisch durch einen zusätz­ lichen Leerlaufkanal (23; 123; 223; 323) zuführbar ist. To a two-stroke internal combustion engine with a carburetor with a gasification part (Venturi) (12), the gasification Solution part upstream intake part (13), a throttle flap part (14), one after the throttle valve part teten output channel (15), a main and a partial load nozzle chamber (16) and a pressurizable fuel supply line, one arranged on a crank chamber (34) Neten cylinder (30) with an inlet channel with an inlet slot (22), the formed in the intake flange (20) lasskanal connected to the output channel of the carburetor is to develop so that an idle stabilization can be achieved, it is provided that the crank chamber (34) fuel-air mixture by an additional Lichen idle channel (23; 123; 223; 323) can be fed.
