1. A gas-liquid separator comprising:
a housing comprising:
a first inlet structured to receive a blowby gas stream, the blowby gas stream having a first flow velocity;
a second inlet structured to a communicate a compressed gas into the housing, at least a portion of the second inlet disposed within the first inlet;
an elastomeric nozzle coupled to the first inlet and positioned around at least a portion of the second inlet, the elastomeric nozzle structured to combine the blowby gas stream with the compressed gas such that the compressed gas causes the blowby gas stream to flow at a second flow velocity greater than the first flow velocity; and
an impaction plate disposed downstream of the elastomeric nozzle such that the blowby gas stream impacts the impaction plate and separates liquid and aerosol contained in the blowby gas stream.
