Soot gathering 27 5-08

  1. 1. SOOT HANDLING CAPACITY API CI-4 vs CJ-4 BPPT Thamrin Jakarta, 27 Mei 2008
  2. 2. Trend performance pelumas mesin diesel• Perkembangan teknologi pelumas mesin diesel secara global dipicu tiga faktor utama yaitu : – Memperpanjang masa ganti oli – Keekonomian bahan bakar – Standar Emisi
  3. 3. Dampak penggunaan EGR• Penggunaan EGR berdampak negatip : – Sebagian besar soot kembali masuk keruang bakar dan bisa masuk kedalam karter (bulk pelumas) – Gas Sulfur Oksida yang korosif dapat kembali masuk kedalam mesin – Pendinginan gas buang yang diresirkulasi mengurangi effisiensi pendinginan yang dapat meningkatkan suhu pelumas yang dapat meningkatkan oksidasi
  4. 4. Impact of Emissions Strategies• The 2007 engines will cost more, Diesel Particulate Filters (DPF) and related hardware are projected to increase the price of a new truck by $6,000 to $10,000.• DPF service which may be required every 150,000 miles, is expected to cost $150 or less each time.• Ultra sulfur diesel fuel (15 ppm S) will cost more : – have a lower heat (BTU) content resulting in increased fuel consumption, – could cause premature injector failure due to its lack of lubricity
  5. 5. API CH-4 : Peningkatan dalam Soot Handling Capability % Soot M API AC C 6% K H-4 Increasing Performance EO / -M API CH-4 5% AP I CG 4% -4 3% AP IC F- 2% 4MACK T-8 TESTING Note : Mack T-8A menggantikan Mack T-7 dalam API
  6. 6. The Dangers of Soot• The combustion process in diesel engines creates soot.• After fuel is injected, combustion occurs with soot as a by-product of the process, and the combustion particulates become trapped on the exposed oil film. The rings wipe the particulates into the oil and the fine particulates aggregate, increasing levels of soot in the oil.• Oil with dispersant additives will generally keep soot in the range of 0.002 to 0.5 microns in suspension;• Detergent additives prevent the build-up of sludge and act as an acid neutralizer, keeping soot in the range of 0.5 to 1.5 microns in suspension.
  7. 7. Soot Causes Wear• Today’s oil manufacturers are extending oil life by holding higher concentrations of contaminants, including soot, in suspension in the oil.• They are also increasing fuel economy by reducing oil viscosity and oil film thickness, therefore reducing the critical contaminant size.
  8. 8. API CI-4• API Service Category CI-4 is oils for use in : – high-speed four-stroke cycle diesel engines designed to meet 2004 exhaust emission standards implemented in 2002. – Use diesel fuels ranging in sulfur content up to 0.5% weight. – It is specifically formulated to sustain engine durability where Exhaust Gas Recirculation (EGR) is used and the impact of these oils on other supplemental exhaust emission devices has not been determined.
  9. 9. Detergent/Dispersant• Detergent mempunyai senyawa polar yang mengandung logam (Ca,Mg,)• Dispersant tidak mengandung unsur logam dan kepolaran dibentuk oleh unsur Oksigen dan atau Nitrogen,
  10. 10. Aktivitas Detergent• Molekul detergen juga mengandung gugus polar dan hidrokarbon tail.• Detergen mungkin senyawa neutral atau mungkin kombinasi dengan material overbased (mis. : Carbonate) untuk menetralisir senyawa asam produk oksidasi. Nilai overbase bervariasi dari (TBN 1-400). Contoh : - Metal phenates, Sulfonate, Salicylates - Sulfonate detergent membentuk micelles
  11. 11. Polaritas metal detergent > kontaminanDetergent yang lebih polar akan menempel lebihkuat dipermukaan dan menggeser kontaminan daripermukaan logam
  12. 12. 5b. DispersantFungsi dispersant adalah :• Menekan pembentukan sludge, deposit dan furnish khususnya pada kondisi temperatur relatif rendah, (operasi stop and go atau opeasi jarak pendek)• Mengendalikan kontaminan : – Produk oksidasi – Carbon (soot) – Debu – Air
  13. 13. Aktivitas DispersantMolekul dispersant terdiri dari polar head (oksigenatau nitrogen) dan hidrokarbon tail (i.e-polybutane)Gugus polar dari beberapa molekul dispersant akanmelingkari produk yang terdegredasi danmencegahnya untuk membentuk Agglomerate
  14. 14. DispersantKondisi :• Produk oksidasi membentuk agglomerate, ukuran bertambah besar dan menjadi insolubeGejala :• Sludge• CloggingAdditive :• Alkanyl Succinimide (PIB-maleic anhydride)• Ester high MW (succinamic anhydride de-glycol)• Mannich base (alkyl phenol-alkylene polyamine- formaldehyde condensation product
  15. 15. API CI-4• Optimum protection is provided against : – corrosive and soot-related wear tendencies – Korosi, keausan dan sifat viscometric terkait kandungan soot tinggi – piston deposits – Degradasi pada temperatur rendah maupun tinggi – oxidative thickening – viscosity loss akibat shearing
  16. 16. API CJ-4• API Service Category CJ-4 designed : – For high-speed four-stroke cycle diesel engines • designed to meet 2007 model year on-highway exhaust emission standards as well as for previous model years. – Spesifically use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). • However, the use of these oils with greater than 15 ppm (0.0015% wt) may impact – exhaust aftertreatment system durability – and/or oil drain interval.
  17. 17. API CJ-4• Will effective of sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used.• Optimum protection is provided for : – control of catalyst poisoning, – particulate filter blocking – engine wear – piston deposits – low- and high-temperature stability – soot handling properties – oxidative thickening – and viscosity loss due to shear.
  18. 18. • Oil with dispersant additives will generally keep soot in the range of 0.002 to 0.5 microns in suspension;• detergent additives prevent the build-up of sludge and act as an acid neutralizer, keeping soot in the range of 0.5 to 1.5 microns in suspension.
  19. 19. Tantangan CJ-4• To ensure protection of the after treatment devices, chemical limits were set for the first time ever for heavy-duty diesel engine oils.• The chemical limits for API CJ-4 target the engine oils commonly referred to as LOW SAPS are : • 1.00 percent maximum sulfated ash (per ASTM D874) • 0.12 percent maximum phosphorus (per ASTM D4951) • 0.40 percent maximum sulfur (per ASTM D4951 or ASTM D2622)
