ABSTRACT:
An inertial impactor that uses gas stream flow rate to separate oil particles in internal combustion engine crankcase emissions. The inertial impactor is particularly adapted for use in closed crankcase ventilation systems. The oil particles have a particle size of from about 0.3 μm to about 0.7 μm. Elimination of the oil particles in the crankcase emission gas stream results in cleaner intake air to the turbocharger air intake system.
