Kapila Wadumesthrige 02/05/08

•

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 :

• 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)

Standard Practice for Condition Monitoring of Used Lubricants by Trend Analysis Using FTIR Spectrometry ASTM E 2412-04 • Carbonyl components 1675 -1800 cm -1 • Water in crank case oil 3500 -3150 cm -1 • Nitrate components 1600 -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
