Show ^ ) ABSTRACT A STUDY OF THE PERFORMANCE OF A COMPRESSION-IGNITION ENGINE WITH MODIFICATIONS TO ENHANCE ATOMIZATION USING ALTERNATIVE FUELS Randolph Cedric Bunt Assistant Engineer Southern Company Services, Inc. (Master of Science, Auburn University, 1982) (Bachelor of Mechanical Engineering, Auburn University, 1979) A 172 CID 4 stroke Ford diesel tractor engine was used for comparative testing of 5 distinct blends of alcohols, agricultural oils, and diesel fuel. SAE test codes were followed for continuous load testing at 85% full power. A spray pattern curve for all of the fuels was obtained by varying the injector nozzle opening pressure. The results were used to predict improved atomization for the alternative fuels by obtaining the same £ for each fuel, the equivalent spray coefficient. With the injectors set for the equivalent spray coefficient, the fuel consumption improved by as much as 10% and brought it to within 2% of that obtained for the standard, diesel fuel #2. ) |
