Abstract

Der Schutzanspruch wird wie folgt bezeichnet:
Zweitaktmotor mit Aus- und Einlassventil bestehend aus einem Auslassventil im oberen Zylinderkopf, Ansaugventil im unteren Zylinderkopf und Einlassventil, das im Kolben mit Kolbenstange eingebaut ist.

Description

  • 2. Beschreibung des Zweitaktmotors mit Aus- und Einlassventil
  • Takt 1) Beim Verdichten wird durch ein Ventil im unteren Zylinderkopf Luft in den Zylinderraum gesaugt, das Ventil schliesst am oberen Totpunkt.
  • Takt 2) Arbeitshub, die angesaugte Luft wird zusammengepresst, kurz vor dem Totpunkt öffnet und schließt das Auslassventil. Das Einlassventil öffnet, die zusammengepresste Luft strömt durch Bohrungen im Kolben, die beim Öffnen des Einlassventils frei werden, in den Zylinderraum.
