Abstract
A crankcase ventilation system for a reciprocating internal combustion engine includes an exhaust outlet and a collector for gathering gases from the engine crankcase. An eductor is connected to the collector and to the exhaust outlet. The eductor includes a generally cylindrical body extending into the exhaust passage of the exhaust outlet and having discharge, clean out, and receiver ports, so that crankcase gases will be drawn through the eductor and discharged into exhaust flowing through the exhaust outlet.
