Abstract

Föreliggande uppfinning avser ett förfarande vid tvåtaktsmotor innefatande åtminstone en cylinder (1) med en fram och återgående kolv (2), ett avgränsat förbränningsrum (5), åtminstone en utloppsport (7) och en inloppsport (9 ) befintlig ovanför utloppsporten vilka båda portar är frilagda vid kolvens nedre vändläge, en aktuator (8 ) om bringar en till denna kopplad ventil 17) öp p na för att tillföra förbränningsluft till förbrännngsrummetvia ett innloppsrör (6) och inloppsporten, ett styrsystem (15) som efter kolvens nedre vändläge beordrar aktuatorn att öppna ventilen.Förfarandet kännetecknas av att ventilen bringas att öppna i anslutningtill att utloppsporten stängs av kolven varvid förbränningslufttillförs samt att tillförseln av förbränningsluftavbryts då kolven stänger inloppsporten.
