Evaluación del desempe o de un motor Yuchai trabajando con biodiesel cubano

At the present work, the authors obtain the engine outer velocity characterization working with Biodieseland its mixtures, and show the chemical composition of the exhaust gases respect to NOx. Is observed adecrease in the engine performance when the Biodiesel per cent is growing. This behaviour must be due tothe lower heat power for Biodiesel respect to Diesel. They obtain a 40% decrease in the NOx formationrespect to Diesel and it is developed an analysis of the reasons of that. Finally they propose the optimizedmixture for the use in an internal combustion engine, about the 20% of Biodiesel, because this is theequilibrium between contamination and engine performance.
