New Dana Piston Ring Technology Reduces Power Cylinder Wear, Emissions

    MUSKEGON, Mich., Jan. 11 /PRNewswire/ -- A new piston ring coating
technology developed by Dana Corporation's (NYSE: DCN) Perfect Circle Division
can extend the life of diesel engine power cylinders by up to 75 percent.
    PCF 380(TM) Coating Technology (patent pending) is a proprietary process
and material combination that reduces porosity and increases the density of
the piston ring coating, resulting in a heavy-duty piston ring that can
deliver more than one million miles of dependable performance.  In addition to
reducing wear, PCF 380(TM) also contributes to reduced oil consumption and
emissions.
    The new technology was developed in anticipation of new heavy-duty diesel
engines, which will employ exhaust gas recirculation (EGR) applications to
reduce emissions.
    "The EGR environment is more abrasive and produces accelerated high-wear
conditions in the power cylinder system," said Tom Neusiis, vice president and
general manager of Dana's Perfect Circle Division.  "Perfect Circle's advanced
coating technology was developed to address this issue, and has worked so well
on piston rings that we are also testing it on cylinder liners and engine
bearings to further increase the life of the entire power cylinder package."
    PCF 380(TM) coating, thermally applied and inlaid into the ring surface,
reduces both ring and cylinder wear, resulting in a 75-percent gain in engine
power cylinder life when compared to today's best technology.
