High-Tech Lubricants for a World in Transition • Engine Oils: • Zinc-Free Low SAPS Engine Oil Technology • Industrial Lubricants: • New Phenomena in Hydraulic Systems • Metalworking: • Replacement of Chlorinated Paraffins in Fine Blanking Operations • Cold Extrusion without applying Conversion Layers (Bondering) • Steel Cold Rolling: • Synthetic Cold Rolling Emulsions Lubricants Russia 2007 Moscow, November 28, 2007 Dr. Georg Lingg
Zn-Free Low SAPS Engine Oils:Formulation Technology Zn-free – Why? • Generally reduced ash formation -> better engine and AT devices cleanliness, higher efficiency for aged engines • Or: at equal ash formation -> more options for more important performance improvements: e. g. cleanliness, better wear protection, higher oxidation stability • Impact on morphology of ash (hard/soft): e. g. injection nozzles • Higher oxidation stability • Better anti-wear protection • Improvement of fuel economy • Minimizing chemical interactions with AT devices: e. g. DeNOx (Oxi-Cat, SCR) Lubricants Russia 2007 Moscow, November 28, 2007 Dr. Georg Lingg
Zn-Free Low SAPS Engine Oils: Impact on Morphology of Ash Sulfated/oxide ashes Sulfated/oxide ashes Ca-Sulfated/Oxide ashes are like “gypsum” soft Lead to less wear Ca/Zn-Sulfated/Oxide ashes are like “ore” hard Lead to more wear Ca-sulfated/oxide are softer and are removed “easier” during normal operation from injector nozzle, piston crown as well as from cylinder head than Zn-sulfate/oxide!
