Presentation Transcript

  1. Biodiesel Cold Flow and Filtering Mark Winston-Galant September 5, 2007 Update Meeting

  2. IntroductionProjects • Engine Work • Install sensors • Exhaust Smokemeter • Biodiesel Cold Flow • Cloud point • Pour point • Cold filter plugging point

  3. IntroductionCold Flow Test Results

  4. IntroductionCold FlowProblems • Biodiesel below cloud point: • Precipitates • Less flow than above cloud point • Biodiesel raised back to above cloud point: • Some precipitate remains • Clog fuel filter in engine

  5. Cold Flow Experimental MethodsGeneral Information • Conjunction with Delphi Automotive • Test flow of fuel after filter • Test different types of biodiesel fuel • Sources (soybean oil, ragweed, etc) • Blends (B5, B10, B20, etc) • Apparatus contained in large freezer to keep uniform temperature

  6. Cold Flow Experimental MethodsApparatus Design From Delphi Automotive

  7. What’s Next • Help Kapila with engine • Price instruments and materials • Build apparatus • Test flow rates
