  1. Research Updates Kapila Wadumesthrige 02/05/08

  2. Engine testing(Kapila, Sidong, Mark and Nick) • Frequency corrected @ 83.9 hrs • 83.9 hrs to 148.2 hrs : 30 kW (60% of Full Load, ULSD) • Total 64 hrs (as of 02/05/2008) • 176 hrs of testing remaining ( 4.4 weeks) • Load bank circuit breaker tripped ( Ran engine ~ one hour without load) • Need in-lab monitoring system (PC Anywhere, E-mail alert system) • Data averaging software installed • Smoke meter • No smoke density / smoke opacity data • Need another shutter in light source side • Remove EGT TC and mount in a different place • Exhaust gas purge lines

  3. Lubricant oil Analysis : • Viscosity- ASTM D 445, 40 C and 100 C • Total base number - D 4739. • Total acid number by ASTM D 664 • Oil Dilution – D 3524 • Pentane Insolubles (%P)- ASTM D 893 • Free Metal analysis- ASTM D 5185 (ICP)

  4. Standard Practice for Condition Monitoring of Used Lubricants by Trend Analysis Using FTIR Spectrometry ASTM E 2412-04 • Carbonylcomponents 1675 -1800 cm-1 • Water in crank case oil3500 -3150 cm-1 • Nitrate components1600 -1650 cm-1 • Antiware components (ZDDP)960 -1025 cm-1 • Gasoline (ZDDP)744 -755 cm-1 • Diesel (JP-5, JP-8)805 -815 cm-1 • EG Coolant 1030 -1100 cm-1 • Soot Loading Absorbance intensity at 2000 cm-1

  5. New Lube Oil ULSD

  6. New Lube Oil ULSD

  7. Soot Analysis • Soot in Lube Oil • Soot in Exhaust Gas

  8. Future Work • Engine Wear Metal Analysis – (ICP AES) ASTM D 5185-05 (Kapila/Nick) • Smoke Meter (Mark) • PC Anywhere set-up (Sidong) • Get ready for S-8 testing (Kapila) • Flush RKA and Titan Fuel Tanks • NELCO 5403 Additive mixing • Calibrate Flow meters for S-8 • Density Measurement for S-8 (Nick) • Lube analysis and Fuel Injection System wear analysis (Nick/Mark) • Protocol for Soot Analysis (Kapila/Nick)

  9. Investigation of DCN • Paper Revised • Accelerated oxidation under reflux condition (Chay finished Cotton Seed BD test) • IR Analysis of oxidative products

  10. Oxidation under Rancimat Conditions

  11. Oxidation under Reflux Conditions

  12. Future work • ICP testing • Experimental outlines for AOCS abstracts
