Abstract
A cylinder-head cover for use in an internal combustion engine, which effectively separates oil and contaminants from blowby gas-oil mixture prior to the time when the blowby gas-oil mixture is suctioned into an intake passage. The cylinder-head cover has extension portions which extend in its lateral direction, and is attached by a curved plate onto its back side, thereby forming a space between the cylinder-head cover and the curved plate. The curved plate has grooves which extends in zigzags relative to its longitudinal direction. The blowby gas-oil mixture passes through the space defined between the cylinder-head cover and the curved plate. As the volume of the space is repeatedly large and small, the flow speed of the blowby gas-oil mixture reduces at the place where the space is large. Hence, the oil or contaminants drop by its weight. Thus, the oil and contaminants, which are contained in the blowby gas, are separated.
