    摘要: An apparatus for reducing crankcase emissions generated by an engine is described. The apparatus generally includes a separator that removes particulate matter from the crankcase emissions and a treatment component that removes odor and gases from the crankcase emissions. The apparatus is configured where the treatment component is disposed downstream of the separator, the separator first removes particulate matter from the crankcase emissions and the treatment component then removes odor and certain gases from the crankcase emissions.

    摘要: A dual stage coalescer includes a separator in a separator chamber separating gas and liquid by inertial impaction, and a coalescer filter element in a coalescer chamber separating gas and liquid by coalescence. A transfer tube extends between the separator chamber and a downstream subchamber in the coalescer chamber at the downstream face of the coalescer filter element, and supplies pre-separated liquid from the separator chamber through the transfer tube to the noted downstream subchamber as driven by pressure differential between the separator chamber and the downstream subchamber, to eliminate a dedicated housing drain outlet from the separator chamber. The coalescer may provide a crankcase ventilation filter for an internal combustion engine having blowby gas containing an air-oil mixture.
