A PCED can include an outer can, an upper lid having an upper lid intake and an upper lid exhaust, a lower lid having a lower lid exhaust, and an internal frame disposed within the can. With the internal frame disposed within the can, first, second, third, and fourth chambers can be formed, with the first chamber containing a coalescing material. Gases from a combustion engine crankcase can enter the PCED via the upper lid intake, move through the chambers, and exit the PCED via the upper lid exhaust and return to the crankcase. While moving through the chambers, impurities within the gas convert to liquid form via condensation, collect in the second chamber, and can be subsequently drained from the PCED via the lower lid exhaust. |

1. A positive crankcase evacuation device, comprising:
an outer can having at least one side can wall, the at least one side can wall defining an open can top, an open can bottom, and a can cavity; an upper lid having at least one upper lid intake aperture and at least one upper lid exhaust aperture; a lower lid having at least one lower lid exhaust aperture; an internal frame, disposed within the can cavity, and having at least one frame side wall defining an open frame top and an open frame bottom, a first baffle, attached to the frame top, and having at least one first baffle aperture, a second baffle, attached to the frame bottom, and having at least one second baffle aperture, and an intake conduit, extending through the first baffle aperture, and having a first conduit end in communication with the upper lid intake aperture, and a second conduit end in communication with a first chamber defined by said internal frame, the first baffle, and the second baffle; an amount of coalescing material disposed within the first chamber; wherein the lower can lid, the second baffle, and the at least one side can wall define a second chamber, the at least one side can wall, the first baffle, and the second baffle define a third chamber, and the at least one side can wall, the first baffle, and the upper can lid form a fourth chamber. |
