Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends

Biodiesel extracted from Scenedesmus obliquus algae through transesterification was used in the current study. Due to disadvantages of using pure biodiesel engines, it as B50 (a blend 50% diesel and biodiesel). To enhance engine performance, n-pentane different extents 5, 10, 15 ml per liter an enhancer additive. Through performance tests, found that best addition caused increase brake thermal efficiency 7.1% a decrease specific fuel consumption 6.4% compared elegant B50. Whereas for exhaust gases, there nitrogen oxides, which associated with significant temperature high oxygen content present In comparison, hydrocarbons emission decreased by 7.2% contrast carbon dioxide increased 22.3% over The monoxide concentrations gases also 17.35% 9.5%, respectively results obtained indicated are improvements pressure evolution heat release data, depend on role mixed n-pentane.
