Abstract

See full text

A cylinder head for an internal combustion engine includes a casting and plug. The casting defines a first channel, a second channel, and a bore extending inward from an exterior surface of the casting. The first channel intersects a central portion of the bore. The second channel intersects an opposing end of the bore relative to the exterior surface. The plug is disposed within the bore. The plug has a distal end that engages the casting along the opposing end of the bore via a slip-fit engagement, a proximal end that engages the casting within the bore proximal to the exterior surface via a fixed engagement, and an intermediate portion that is spaced apart from the casting along the central portion of the bore. The plug defines an internal channel that establishes fluid communication between the first and second channels.
