Dana's Intelligent Lubrication System Electronically Manages Oil Flow, Improving Durability, Fuel Efficiency, and Emissions

Oct 21, 2002

    TOLEDO, Ohio, Oct. 21 /PRNewswire/ -- Convergence 2002, Booth # 520 --
Dana Corporation's (NYSE: DCN) Intelligent Lubrication(TM) system matches
real-time engine and transmission oil demands with a controlled, consistent
oil supply.  This unique approach enhances durability, reduces cold start
emissions, saves fuel, and extends oil change intervals.

    The Intelligent Lubrication system features a secondary electric oil-boost
pump, which meets peak oil demands at low engine speeds and supplements a
downsized, conventional engine-driven oil pump.
    "Smaller, higher performance engine and transmission packages have
resulted in growing demands on the lubrication system, which can limit vehicle
performance," said Mike Laisure, president of Dana's Engine and Fluid
Management Group.  "By matching oil supply to oil demand, Dana's Intelligent
Lubrication system brings significant benefits to engine and transmission
performance."
    The system can pre-prime the engine prior to start-up, which eliminates
dry running and reduces starting torque during cranking.  It also can be used
to initialize variable valve timing, to reduce cold start emissions.
    By reducing the size of the engine driven oil pump, the system reduces
parasitic energy losses and saves fuel.  During times of peak oil demands, oil
temperature and oil pressure sensors provide real-time data to microprocessors
in the engine control unit, which can then engage, or increase the speed of,
the electric boost pump.  Oil supply and demand are precisely matched,
resulting in optimal performance, less recirculation of oil and longer oil
change intervals.
    In addition to making the conventional pump smaller, the arrangement can
be standardized across entire engine or transmission families. This helps to
offset the cost of the secondary pump and results in improved logistics and
greater flexibility at the engine assembly facility. The electric pump can be
remotely mounted for maximum packaging flexibility, and operates on a standard
12-volt power supply, with 42-volt versions available if required.
    Dana's expertise in "smart gaskets" extends beyond oil temperature and
pressure sensors, to also enable sealed electronic pathways for internal
electronic engine systems.  For example, an "electronic window" cylinder head
cover gasket features an integrated electrical connector and wiring harness
assembly, creating a sealed electrical bridge to provide power to fuel
injectors and a glow plug. A transmission pan sealing module also features an
electronic window to enable electronic shift control.  This patented window
connector technology reduces part complexity and improves ease of assembly
while reducing the risk of potential leak paths.
