Sunflower methyl esters for direct injected diesel engines

ABSTRACT A methyl ester of sunflower oil was durability tested in direct injected, turbocharged and intercooled diesel engine. A test cycle recommended by the Alternate Fuels Committee of the Engine Manufacturer's Association was used. The results are compared to a baseline test using diesel fuel. Based on the results, the methyl ester fuel successfully completed the 200-hour durability test. Field tests and engine manufacturers evaluations are needed to further quantify the long term effect of the fuel on engine durability.
