Abstract

Method for cleaning the crankcase gases (2) of a combustion engine (1), comprising the step of causing the crankcase gases to pass through a catalyst (4). The method is distinguished particularly by the step of causing a catalyst (4) arranged separately for cleaning the crankcase gases to be warmed by a separated flow of exhaust gases (5) from the engine (1) which is added to the crankcase gases (2) before they are led to the catalyst (4). The amount of the separated flow of exhaust gases which is added to the crankcase gases is controlled under the influence of a mixing valve (7). The invention also relates to a device for cleaning and to a combustion engine (1).
