ABSTRACT:
An air pollution control device for use with automobile engines for filtering crankcase and exhaust emissions. The device comprises a filtering chamber containing fluid coated filtering material having an inlet of a first diameter, an outlet of a second, larger diameter to cause a decrease in internal pressure of the air-pollutant mixture entering through the inlet, a controlled gas flow path through the filtering material in the device, a source of fluid for renewing the fluid coating on the filtering material, a fluid reservoir and means for recirculating the fluid for the filtering material. A pair of such devices, one for use with the crankcase emission blow-by system and one for use with the exhaust system of an internal combustion engine provides significant reduction in all exhaust emissions from the engine. Filtering material fluid for each device is recirculated using an independent recirculating system or utilizing the oil circulation system of the engine.
