OIL SEPARATOR UNIT AND OIL SEPARATOR STRUCTURE

摘要

In a blow-by gas collision region, a protruding surface protruding downwards is formed on a lower surface of at least one of baffles. Blow-by gas is made to collide with the protruding surface, thereby aggregating oil mist particles in the blow-by gas with oil mist particles already adherent to the protruding surface. This allows part of the oil mist particles to become oil droplets exhibiting liquid properties in any way, the oil droplets to be sequentially moved along the protruding surface to the lowest surface (top surface) thereof by gravity, and the oil droplets to be aggregated with each other at the lowest surface.
