Abstract
An engine assembly includes an engine defining a combustion chamber and a crankcase volume, and an intake assembly having an air cleaner assembly, a throttle, and an intake manifold in a series arrangement and fluidly coupled with the combustion chamber. A first and second air-oil separator may define respective first and second separator volumes, each respectively configured to extract oil from air flowing through the volume. A first conduit may fluidly couple the crankcase with the first separator volume, a second conduit may fluidly couple the intake manifold with the first separator volume; a third conduit may fluidly couple the crankcase with the second separator volume; a fourth conduit may fluidly couple the air cleaner assembly with the second separator volume; and a fifth conduit may fluidly couple the air cleaner assembly with the first separator volume.
