Research updates

  • 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)
