ENGINE PCV SYSTEM WITH HYDROPHOBIC, OLEOPHOBIC MEMBRANE FOR AIR/OIL SEPARATION |
摘要 |
An engine crankcase emission control system for an internal combustion engine includes a cylinder air intake system connected to associated engine cylinders. The system also includes an engine crankcase. A crankcase air outlet connects the crankcase to the cylinder air intake system at a location subject to variable intake vacuum pressures to allow crankcase vapors to be drawn into inlet air passing to the cylinders. A hydrophobic, oleophobic membrane covers the crankcase air outlet. The membrane inhibits the passage of oil and water out of the crankcase through the crankcase air outlet.
