Abstract: An oil baffle, a system, and a method are disclosed for separating a gaseous component from oil in a blow-by vapor for an internal combustion engine. An example system may include a cam cover configured to be mounted on a cylinder head. The system may also include an oil baffle that may have a generally planar body with a first face and a second face opposite the first face. The first face may be coupled to the cam cover and may define an oil separation chamber between the cam cover and the first face. The oil baffle may include one or more stiffening members coupled to and extending from and substantially normal to the second face.

Abstract: A throttle for an internal combustion engine wherein intake runners (18) include slots (24) through which a slide throttle plate (26) is mounted. The throttle plate includes openings (28) selectively aligned with the runners (18) by an actuator (32) to control the air flow into the engine intake ports (14). Actuation back and forth across the runners (18) can provide for flow control as well as port deactivation, while a throttle plate (226) configured for up and down motion relative to the intake runners (218) can provide for tumble port flow control.

The throttle plate includes openings (28) selectively aligned with the runners (18) by an actuator (32) to control the air flow into the engine intake ports (14). Actuation linearly across the runners (18) provides for tumble port flow control and idle control, as well as port deactivation.
