Abstract

Für Otto-Motore wird ein Vergaser angegeben, der an erforderliche Motorleistungen flexibel anpassbar ist. Der Vergaser weist einen Lufttrichter (Fig.1, (1)) zum Ansaugen von Brennstoff aus einer in den Lufttrichter mündenden Brennstoffleitung (3) auf, die an einer Brennstoffkammer (5) angeschlossen ist und zwischen der Brennstoffkammer und ihrer Mündung (4) im Lufttrichter eine Brennstoffdüse (7) zur Einstellung der anzusaugenden Brennstoffmenge aufweist. Der Brennstoff wird aufgrund von Unterdruck im Lufttrichter aus der Brennstoffkammer abgesaugt. Um schädliche Abgasemissionen zu vermindern und Energieverluste für das Gesamtsystem zu vermeiden, weist die Brennstoffdüse (7) einen mittels eines piezoelektrischen Aktuators (8) veränderbaren Strömungsquerschnitt auf. Mit dem piezoelektrischen Aktuator lässt sich der Stromungsquerschnitt sehr feinfühlig einstellen. Im Ausführungsbeispiel nach Figur 1 steht der Aktuator mit Stellglied (10) in Wirkverbindung. Der Aktuator reagiert unmittelbar auf sich verändernde Regelwerte. Von wesentlichem Vorteil ist insbesondere die in Zusammenhang mit Kleinmotoren gegebene Betriebssicherheit. Der piezoelektrische Aktuator (8) kann als Biegewändler oder als piezoelektrische Membran oder als in axialer Richtung wirksamer Aktuator ausgebildet sein.
