System for improving engine crankcase ventilation via a conduit

[0020]The present description is related to PCV flow of an internal combustion engine. In one embodiment, an eight cylinder engine as shown in FIG. 2 and having a lateral force PCV valve as shown in FIGS. 3-6B improves PCV flow by limiting oil intrusion into the PCV path. FIG. 7 shows a method for controlling PCV flow during periods of higher lateral or centripetal forces.

[0021]Referring to FIG. 1, internal combustion engine 10, comprising a plurality of cylinders, one cylinder of which is shown in FIG. 1, is controlled by electronic engine controller 12. Engine 10 includes combustion chamber 30 and cylinder walls 32 with piston 36 positioned therein and connected to crankshaft 40. Combustion chamber 30 is shown communicating with intake manifold 44 and exhaust manifold 48 via respective intake valve 52 and exhaust valve 54. Each intake and exhaust valve may be operated by an intake cam 51 and an exhaust cam 53. Alternatively, one or more of the intake and exhaust valves may be operate
