DELGADO, Arnoldo Emilio; APERADOR CHAPARRO, Willian  and  SILVA GONZALEZ, Jorge Réne. Influence of castor oil mix composition on the production of biofuel. Rev.fac.ing.univ. Antioquia [online]. 2011, n.58, pp.46-52. ISSN 0120-6230.

Castor oil trans esterification has been evaluated as a source of alternative biodiesel. Three mixtures of biofuel (B5% B10% and B20%) were tested in a diesel engine. Power, fuel consumption, temperature and exhaust emissions were measured. Also, densities, viscosities, refractive indexes and combustion heats of the mixtures were determined. The use of biodiesel mixtures produces an increase of viscosity and fuel consumption, decreasing the heating and engine power, reducing the combustion gases like CO, CO₂, sulfur oxides, hydrocarbons, and lowering the opacity of exhaust emissions. Additionally, a balance in the observed diesel engine performance was evidenced by the engine temperatures.

Keywords : castor oil; biofuel; densities; viscosity; combustion; gases.
