Abstract:
1. An engine gas-oil separator for separating oil contents in blow-by gases that are recirculated to an intake system, the separator comprising: a head cover; a lower plate attached to the head cover to define a separation chamber between an upper internal surface of the head cover and a lower internal surface of the lower plate; a plurality of upper baffles disposed in the separation chamber and depending downwardly from the upper internal surface of the head cover; a plurality of lower baffles disposed in the separation chamber and extending upwardly from the lower internal surface of the lower plate, wherein the plurality of upper baffles and the plurality of lower baffles are configured to impart a swirling flow of blow-by gases in a generally longitudinal direction through the separation chamber; a first longitudinal wall extending between the upper internal surface and the lower internal surface, the first longitudinal wall defining a longitudinal first inner surface, which further defines the separation chamber; and a second longitudinal wall extending between the upper internal surface and the lower internal surface and spaced from the first longitudinal wall, the second longitudinal wall defining a longitudinal second inner surface, which further defines the separation chamber, wherein the plurality of upper baffles includes a plurality of first upper baffles and a plurality of second upper baffles, wherein adjacent the first longitudinal wall each first upper baffle is spaced a longitudinal distance d wherein adjacent the second longitudinal wall each first upper baffle is spaced a longitudinal distance d
