LONG-TERM OPERATION OF A TURBOCHARGED DIESEL ENGINE ON SOYBEAN OIL FUEL BLENDS

摘要: It has been known for more than 50 years that some diesel engines could be fueled short periods with vegetable oils, either neat or hydrocarbon fuel additives. World overproduction of soybean oil is increasing its potential as an economical extender. The subject test program was undertaken to determine long-term effects this alternate on a modern, high-speed engine. choice (soybean oil) alternative engine extender rather the other major biomass motor (ethanol) related relative properties these fuels. common U.S. oils are much closer (No. 2D) ethanol in both cetane rating and volumetric energy content. Unlike ethanol, can blended 1:1 No. 2D produce power consumption levels practically identical those obtained 100% fuel. However, operation laboratory bench tests demonstrated blends were unsatisfactory continuous use. reasons difficulties determined satisfactory blend proven through prolonged testing.
