  • Intake manifold with a heated PCV passage
    Patent number: 6390080
    Abstract: An intake manifold 7 for an internal combustion engine is provided which has an intake venturi passage 34 for throttled passage of filtered air into a plenum 44. A crankcase ventilation passage 70 is provided having a first end 72 intersecting with the venturi passage 34 and a second end 74 intersecting with an outer boundary of the manifold. A heat pipe 82 is adjacent a major portion of the crankcase ventilation passage 70 between the first and second ends 72, 74 for transfer of thermal energy to prevent freeze up in the crankcase ventilation passage 70.
