Abstract
An oil separator arrangement for an internal combustion engine incorporates a vortex chamber oil separator with a vortex chamber extending in a longitudinal direction, where the vortex chamber includes a wall extending in a longitudinal direction, a gas inlet, and a gas outlet opening. The gas inlet is disposed tangential to the wall for tangentially blowing-in of blow-by-gas into the vortex chamber, so that at least one gas vortex flow rotating helically along the wall in the longitudinal direction is generated, where at least one further oil separator is connected in parallel to the vortex chamber oil separator. The further oil separator incorporates a separation chamber with an inlet-side spring tongue automatically controlled by the applied blow-by-gas, and a baffle wall disposed downstream the spring tongue.
