  • Hydroformed port liner
    Patent number: 7305763
    Abstract: A cylinder head (10) for an internal combustion engine has hydroformed port liners (18) positioned within selected ports, either exhaust and/or intake ports (14, 16). The hydroformed port liner (18) includes an air gap (24) for an insulation layer within the selected port (14, 16) between an outer surface (19) of the hydroformed port liner (18) and the wall of the port (14, 16). A cylinder head (12) with a predetermined port configuration has selected ports (14, 16) cast with protrusions (22). The selected ports (14,16) have a larger diameter than a standard size port diameter for that cylinder head to provide a predetermined port configuration by a preset amount based on the thickness of the hydroformed port liner (18) and a desired air gap (22). Protrusions (22) in the wall of the selected ports (14, 16) or on the insert sleeves (17) facilitate formation of the air gap during the hydroforming process.

  • Hydroforming of composite materials
    Patent number: 6631630
    Abstract: The present invention provides an apparatus and a method which use hydroforming to shape complex structures from materials such as sheet metal or composites. In particular, an apparatus and a method for shaping complex structures using composites such as continuous-fiber or woven fiber composites with limited wrinkling or rupture of the composite during the shaping process.
