The gasket is unique in that it provides "windows" to power circuits for the fuel injectors. Depending on the need, this type of gasket can also provide power connections for solenoids, sensors, actuators, and glow plugs.
By using this technology with single or multiple connections, Dana's electronic "window" gasket simplifies production by reducing the number of components and lowering assembly time and costs. Other advantages include multiple conductor sizes, integrated wiring harnesses, and an increased resistance to heat extremes.
Integrating sealed wiring connections directly into the window gasket eliminates the need to seal wire routing holes that are machined directly into the structural engine components, eliminating potential leak paths. Improved serviceability is another benefit of Dana's electronic window gasket technology, allowing the gasket and harness module to be removed and reused without jeopardizing wiring integrity upon reassembly.
"Being able to offer an efficient means of routing electrical energy into an engine while underwriting sealing integrity is a significant engineering accomplishment," said Ralf Goettel, president, engine products for Dana. "The electronic pass-through design not only speeds the assembly process, but also eliminates costly and potentially damaging leak paths."
In addition to conventional sealing applications, Dana's electronic window gaskets can be integrated into cylinder head covers, transmission pan modules, windage trays, and oil-pan assembly applications.
