Abstract

See full text

The invention related to a two-stroke internal combustion engine (1), comprising a crankcase (2), which has an air intake (3), and at least one cylinder (4), which is connected to the crankcase (2) and which, together with a piston (5) arranged therein, defines a combustion chamber (6). The cylinder (4) has at least one air inlet (7), which via an air duct (8) communicates with the crankcase (2), in which a mixture of air and lubricating oil and fuel, if any, is contained. The air duct (8) is connected to the crankcase (2) via a separator (10) for cleaning of air coming from the crankcase (2) from lubricating oil and fuel, if any. The separator (10) has a centrifugal chamber (11), in which the lubricating oil and the fuel, if any, in a circulating motion are thrown outwards to a circumferential wall (12) and thus substantially cleaned air is passed, through a chamber outlet (13), which with respect to said circulating motion is a radially inner outlet, to said air duct (8) to be supplied to the combustion chamber (6) through the air inlet (7).
