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 Source: Gas engine oil field test with Ganymet Plus Sulfated/oxide ashes Sulfated/oxide ashes 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! 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 Zn-Free Low SAPS Engine Oils: Impact on Morphology of Ash
