  • Positive crankcase ventilation (PCV) device and engine assembly employing the same
    Patent number: 9945334
    Abstract: An engine assembly is provided with an intake manifold having a manifold body downstream of a fresh air intake port. The manifold body has a wall defining first and second apertures spaced apart from one another. A positive crankcase ventilation (PCV) device is provided with a PCV pipe having a first end in fluid communication with a crankcase and a second end connected to first and second PCV branches. The first and second PCV branches are in fluid communication with the first and second apertures. A method is provided and directs a first portion of gases from the crankcase to the first aperture via the PCV pipe and the first PCV branch, and directs a second portion of gases from the crankcase to the second aperture via the PCV pipe and the second PCV branch.
