03 vice chairman of maspi, nugraha kartasasmita

  1. 1. Nugraha KartasasmitaVice Chairman - Indonesian Lube Society (MASPI)
  2. 2. Fundamental Drivers of Lubricant Quality1. TECHNOLOGY – ENVIRONMENTAL – FUEL ECONOMY DEMAND2. FUEL TREND DEMAND
  3. 3. Technology Environmental – Fuel EconomyEnvironmental End User Demand OEM Respons Lubricant ResponsDemand• Emission • Reduce burden of • Engine/Equip- • Higher Quality Legislation Ownership ment Changes • Extended Drain• Corporate • Extended drain • Exhaust After Average Treatment Treatment• Fuel Economy • Higher reliability • Exhaust After • Device Standard • Lower Operation Treatment Device Compatibility • Lower Life Time • Improved Fuel • Fuel Economy Cost Efficiency
  4. 4. Future Lubricant Engine: Higher speed Higher efficiency Higher operating temperature Lower emission Compatibility to renewable fuel Lubricant : Lower viscosity Higher oxidation stability Higher viscosity index Compatibility to renewable fuel
  5. 5. Lubricant Improvement
  6. 6. Implication for LubricantProduct Continuous up-gradation of lubricant quality levels: SAE 15W40 / 10W30 / 10W40 / 5W40 / 0W30 / 0W20 Group II / III / IV/V base stocks
  7. 7. 2. FUEL TREND DEMAND
  8. 8. Bio-Fuel = Future Fuel Source: Product form: Vegetable Oils ester (Fatty Acid Methyl Animal Fats Esther FAME) Process: Trans glycerin Esterification FAME blended with Using Alcohol Diesel Fuel at: (Methanol/Ethanol) 5% (B5), 10% (B10), 20% (B20)
  9. 9. Bio-Fuel = Future Fuel Europe: Rape seed methyl ester Typically B05 United State (US): Soy bean methyl ester Bio-diesel typically B20 Asia Pacific: Palm oil methyl ester Typically B05
  10. 10. Impact Bio-Fuel toLubricant Impact of bio-diesel on: engine cleanliness potential consequences of fuel dilution contamination of the engine oil Droplet characteristics + lower volatility + spray pattern + wall impingement non-combusted bio-diesel (past the piston rings) fuel dilution
  11. 11. Oxidation Unsaturated (particularly polyunsaturated fatty acid esters: derived from corn, olive and sunflower oils) exhibit poor oxidative stability Un burnt bio-diesel entering the oil sump oxidized lubricant degradation and thickening
  12. 12. Injector Fouling Free fatty acids + water increased corrosion of the injector system Presence of glycerol + viscous glycerides contribute injector coking Higher quantities of bio-diesel increase injector fouling (due to the thermo-oxidation and thermal polymerization properties of unsaturated bio-diesel) If injector tip deposits build up spray pattern disrupted piston deposits increase ring-sticking and increase fuel dilution
  13. 13. Wear and Corrosion High level of fuel dilution reduce the oil viscosity lower oil film thickness higher friction higher wear
  14. 14. Oil Quality Bio-diesel entering the oil sump may undergo oxidative polymerization severe sludge precipitation significant loss of dispersancy / antioxidancy increase in piston deposits ring- sticking
  15. 15. Conclusion Support Future Emission Regulation Lower viscosity Higher viscosity stability Higher oxidation stability Compatibility to Bio-Fuel Higher oxidation stability Higher viscosity stability Better dispersancy Better detergency Higher thermal stability
