ABSTRACT:
A system for withdrawing vapors from the crankcase of an internal combustion engine and directing the vapors into the air intake manifold thereof for combustion within the engine is described which comprises a first vapor flow circuit interconnecting the crankcase in vapor flow communication with the air intake manifold at a region thereof where a vacuum is generated or maintained, the first circuit including in a described embodiment, an orifice and expansion chamber for expanding and cooling the vapors to an aerosol state; a second vapor flow circuit of generally lower flow impedance than that of the first circuit may be included on certain engine-fuel/air system types for interconnecting the crankcase in vapor flow communication with the air cleaner of the fuel/air system for conducting vapor to the carburetor at high throttle operating conditions.
