Research Updates Kapila Wadumesthrige 03/04/08
Engine testing(Kapila, Sidong, Mark and Nick) • Total run time = 292 hrs • Total testing time ( 30 kW (60% of Full Load, ULSD) = 205 hrs • 35 hrs of testing remaining ( 4 days) • 500 gallon tank empty • Need about 50 gallons of ULSD • Clean fuel tank for S8 • Continuous Lube oil analysis • Metal analysis • Fuel Injector system durability testing
Effect of Cetane improvers on oxidation stability of Biodiesel • Antioxidants and cetane improvers act against each other • Cetane improvers in B20 (ULSD) may help oxidize biodiesel and degradation of antioxidants • Received two cetane improvers • 2-ethyl-hexyl nitrate (EHN) • di-tert-butyl peroxide (DTBP)) • Stability of antioxidants in the presence of cetane improvers
ICP testing • All metal standards and solvents received • Compressed air line installed (Mark & Danton) • Methods for Biodiesel and Lube oil analysis
