GENERATION OF A VACUUM IN THE CRANKCASE FOR REDUCING PARTICLES NUMBERS

The invention relates to a device (V) for an internal combustion engine, in particular for generating negative pressure in a crankcase (1) and/or for venting a crankcase (1), comprising a crankcase (1), at least one combustion chamber (4), at least one oil separator (16) connected to the crankcase (1), and at least one pressure adjustment device (17) which is designed to establish a negative pressure in the crankcase (1) during operation, so that the pressure difference between the crankcase (1) and the combustion chamber (4) is appropriately reduced.
