slide2
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
lubricant oil analysis
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)

  • 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
