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.
