Dana Corporation to Provide Proprietary Sealing Technology for Nissan's all New 5.6L V-8 Engine
Jan 9, 2003
TOLEDO, Ohio, Jan. 9 /PRNewswire-FirstCall/ -- Dana Corporation's (NYSE: DCN) Engine and Fluid Management Group announced today that it has been selected to supply its proprietary Wave-stopper(TM) multi-layered steel (MLS) cylinder head gasket for Nissan's new 5.6L V-8 engine, which will power the automaker's new 2004 Titan full-size pickup and an upcoming full-size SUV.

Additionally, reduced cylinder bore spacing eliminates weight and creates a more compact engine package. Sealing land geography was limited by this high-tech, compact design and proved to be an ideal application for the Wave-stopper MLS cylinder head gasket. The MLS cylinder head gasket's combustion seal feature, commonly referred to as a "stopper," is a zone of the gasket at the bore opening which is thicker than the rest of the gasket. MLS gasket "stoppers" have traditionally been constructed of a folded layer, an embossed spacer layer, a welded shim, or a combination of multiple layers folded in complex relationships. Dana's Wave-stopper incorporates a unique embossment into the selected gasket layer(s) to provide a precisely controlled stopper action to seal the combustion chamber. This also serves to integrate the stopper effect into an active layer, meaning a single layer can now perform dual task functions as a stopper and dynamic sealing bead. Prior to the Wave-stopper, head gasket design was locked into a single constant stopper thickness around the bore, which was dependent on steel thickness in the fold-over layer or in the welded shim. The Wave-stopper height can be optimized to meet the rigidity requirements of each individual engine and can easily be contoured to provide topography if required. "The Wave-stopper was developed as a response to rapidly changing engine characteristics and architecture," said Mike Laisure, president of Dana's Engine and Fluid Management Group. "This is just one example of Dana's commitment to supply technologically relevant products that enable our customers to meet their many durability, weight, NVH, fuel economy, and packaging issues." Additionally, Dana's proprietary F50 Intellicoat(TM) technology is used to selectively screenprint the gasket, coating only the areas required for optimal sealing. The Dana Engine and Fluid Management Group produces a full line of sealing, bearings, fluid system and power cylinder products that help automakers achieve their goals in key areas such as durability, noise vibration and harshness (NVH), fuel economy, emissions reduction, and the management of essential operating fluids.
