Dana's Ron Rutunno discusses Victor Reinz® gasket technology at the 2019 AAPEX Show in Las Vegas, NV.
This 6.6 liter GM Duramax engine features Dana’s patented Wave-Stopper™ technology, which combats “head lift,” a phenomenon common in diesel engines.
The innovative Wave-Stopper design utilizes topography within the gasket structure to create a highly uniform seal. Specifically, several concentric “waves” are embossed in an active functional inner layer, preventing over-compression of the bore bead. The topography allows Dana engineers to vary the bead height between bolt spans, resulting in more uniform sealing stress at the combustion opening. Uniformity results in less bore distortion and improved piston ring seal. The Wave-Stopper layer acts a secondary combustion seal.
