  • Separator and oil trap for closed crankcase ventilator systems
    Patent number: 6460525
    Abstract: A separator for a closed crank case ventilation system has an upstream located inlet and downstream gas and oil outlets. A plurality of flat plate baffles alternately extend from opposing side walls to form a tortuous path for blow by gasses to separate the oil from the gasses. The separator is located upstream from the crankcase depression regulator such that the pressure differential between the separator and the crankcase is minimal to allow the oil to easily open the check valve and return to the crankcase.
    Type: Grant
    Filed: February 4, 2002
    Date of Patent: October 8, 2002
    Assignee: Detroit Diesel Corporation

  • Piston ring with hybrid face coating
    Patent number: 6161837
    Abstract: An improved piston ring is disclosed, together with a process form making the ring. An annular steel base body has a lower layer formed by electro-plating a peripheral surface of the body with either a chromium or titanium nitrided gas. The ring is normally lapped until dull, smooth and free of residual metallic plating nodules, yielding random micro-abrasions in the lower layer. An upper layer of metallic nitride or chromium ceramic is formed onto the lapped lower layer, using physical vapor deposition means.
