A piston has a piston body extending along a central axis. The piston body has an upper crown portion and a lower crown portion. The upper crown portion has an upper combustion wall and an at least one annular upper rib depending from the upper combustion wall to a free end. The lower crown portion has at least one annular lower rib extending to a free end that is fixed to the at least one upper rib and an inner gallery floor extending radially inwardly relative to the at least one lower rib. The upper crown portion has an upper post depending from the upper combustion wall along the central axis to a free end. The lower crown portion has a lower post extending upwardly from the inner gallery floor along the central axis to a free end. Together, the upper post and the lower post form a labyrinth passage.

A low profile fold protective textile sleeve for bundling elongate members has longitudinally and laterally interlaced monofilament warp and fill yarns. Flat profile monofilaments are employed in the warp direction and round monofilaments in the fill direction. The flat monofilaments are considerably wider than they are thick, and provide the sleeve with flexibility and bending out of the plane of the sleeve. The round monofilaments may be sized so that their diameter is about the same as the thickness of the flat monofilaments, and they can be bundled together so that the effective width of each bundle approximates the width of the flat monofilament yarns with which they are intertwined. The round monofilaments are heat-set along at least a portion of their length to provide biased living hinge regions of the sleeve, while also lending strength and stiffness to the sleeve along the fill direction.

A piston for diesel engine applications has a piston body cast entirely of one piece of steel and includes a piston head with a combustion bowl, a ring belt and an oil cooling gallery. A pair of pin bosses and a piston skirt are cast as one piece with the piston head out of the same steel material.
