Abstract
An apparatus for the treatment of gases in a positive crankcase ventilation (PCV) system, in an internal combustion engine, is provided with a housing defining a gas treatment chamber. At least one gas filtering medium is disposed in the treatment chamber, and the gases from the engine crankcase are passed through the gas filtering medium in the treatment chamber, before the gases are routed into the air intake portion of the engine. In addition, the gases, after passage through the gas filtering medium, are passed through an ionization device.
