Abstract
The invention related to a two-stroke internal combustion engine (), comprising a crankcase (), which has an air intake (), and at least one cylinder (), which is connected to the crankcase () and which, together with a piston () arranged therein, defines a combustion chamber (). The cylinder () has at least one air inlet (), which via an air duct () communicates with the crankcase (), in which a mixture of air and lubricating oil and fuel, if any, is contained. The air duct () is connected to the crankcase () via a separator () for cleaning of air coming from the crankcase () from lubricating oil and fuel, if any. The separator () has a centrifugal chamber (), in which the lubricating oil and the fuel, if any, in a circulating motion are thrown outwards to a circumferential wall () and thus substantially cleaned air is passed, through a chamber outlet (), which with respect to said circulating motion is a radially inner outlet, to said air duct () to be supplied to the combustion chamber () through the air inlet ().
