Structural oil baffle for engine covers

An engine system comprising:

• a cam cover mountable on a cylinder head;
• and
• an oil baffle having:
• a generally planar body with a first face and a second face opposite the first face, the first face coupled to the cam cover and defining an oil separation chamber between the cam cover and the first face;
• and stiffening members coupled to, extending from, and substantially normal to, the second face, wherein the oil baffle first face is generally rectangular and has first and second spaced apart longitudinal edges, and first and second transverse edges, the first transverse edge being at an inlet end and the second transverse edge being at an outlet end of the oil separation chamber;
• the oil baffle attached to the cam cover in an attachment pattern, the attachment pattern including a substantially continuous first attachment arranged at or adjacent to the first longitudinal edge, the second transverse edge, and the second longitudinal edge;
• a second attachment disposed substantially parallel to the first transverse edge and being shorter than the first transverse edge to provide a passage between the first attachment and the second attachment;
• and
• two or more interior attachments arranged in and/or adjacent to the passage to provide a tortuous path for a blow-by vapor as the blow-by vapor passes from the inlet end to the outlet end.

An engine, comprising:

• a cam cover mounted on a cylinder head;
• and
• an oil baffle having:
• a generally planar body with first and second oppositely positioned faces, the first face coupled to the cam cover and defining an oil separation chamber between the cam cover and the first face;
• stiffening members coupled to, extending from, and substantially normal to, the second face;
• and
• cylinders extending from the second face and disposed around sparkplug access areas.
