  • Ferrous pistons for diesel engines having EGR coating
    Patent number: 6606983
    Abstract: A corrosion resistant piston for use in an exhaust gas recirculation diesel engine. The piston includes a crown portion having ring grooves formed around a periphery of the crown portion. The ring grooves are separated by ring lands. The piston also includes a piston rod connecting portion that extends from the crown portion. The piston is made of steel and includes an electroless coating of nickel having a maximum thickness of 8 micrometers.
    Type: Grant
    Filed: September 18, 2001
    Date of Patent: August 19, 2003

  • Cylinder liner for diesel engines with EGR and method of manufacture
    Patent number: 6588408
    Abstract: A ferrous cylinder liner for use in diesel engines having exhaust gas recirculation (EGR) is protected from corrosive attack from the EGR environment by first final machining the inner running surface of the liner and thereafter plating the finished inner surface with a thin, non-porous, continuous coating of chromium which serves as a barrier to the EGR gases. The liner is installed and used in its as-coated condition with no post-coating finishing of the coated surface.

  • Cylinder liner having EGR coating
    Patent number: 6508240
    Abstract: A ferrous cylinder liner for use in diesel engines equipped with exhaust gas recirculation has at least a portion of its inner surface covered by an electroless coating of nickel. The coating has a maximum thickness of 8 micrometers and presents a continuous, non-porous barrier which protects the ferrous liner against attack from the corrosive EGR environment.
