Engine durability screening test of a diesel oil/soy oil/alcohol microemulsion fuel

Abstract

A hybrid fuel and No. 2 diesel fuel were burned in direct-injection diesel engines to compare the effects of the fuels on engine durability. The hybrid fuel was a microemulsion of soybean oil, diesel fuel, 190-proof ethanol and 1-butanol. The engines were run for 200 hr on each fuel with loads and speeds controIled by computer according to a cycle suggested by the EMA (Engine Manufacturer's Association). Engines were disassembled before and after the runs to determine the difference in wear and carbon deposits. The engine running on the hybrid fuel completed the 200-hr EMA test without difficulty. The hybrid produced less engine wear than diesel fuel, but produced greater deposits of carbon and lacquer on the injector tips, intake valves and tops of the cylinder liners. Also, engine performance was degraded ca. 5% at the end of the 200-hr test.

Biodiesel: an overview

“…Microemulsions improve spray characteristics by explosive vaporization of the low boiling constituents in the micelles. 6 Microemulsions from vegetable oils and methanol have a performance similar to diesel. 7 2-Octanol is an effective amphiphilic in the micellar solubilization of methanol in triolein and soybean oil.…”

A Kinetic Study of the Fermentation of Cane Sugar Using <i>Saccharomyces cerevisiae</i>

“…Alcohols from vegetable sources are useful as renewable components of bio-diesel as well as for the production of a range of useful chemicals such as surfactants, solvents for paints, vanishes, inks and adhesives [1,2]. In addition, alcohols are used for medicinal, pharmaceutical, flavoring and beverage purposes.…”

00/00868 Biodiesel production: a review

“…The condensed organic phase was fractionated to produce biogasoline and biodiesel fuels. The chemical compositions (heavy hydrocarbons) of the diesel fractions were similar to Table 6 Compositional data of pyrolysis of oils (Alencar et al, 1983;Schwab et al, 1988) Percent by weight Table 5 Properties of shipp nonionic fuel (Goering and Fry, 1984a) fossil fuels. The process was simple and eective compared with other cracking processes according to the paper.…”

“…Shipp nonionic (SNI) fuel containing 50% No. 2 diesel fuel, 25% degummed and alkali-re®ned soybean oil, 5% 190-proof ethanol and 20% 1-butanol was evaluated in the 200 h EMA screening test (Goering and Fry, 1984a). The fuel properties are summarized in Table 5.…”
