Abstract

CI engines are preferred worldwide in heavy hauling for their efficiency and torque. But, these engines are known for their notorious NOx and black smoke emissions. Newer emission norms all around the globe have put limits on the emission of nitrogen oxides and particulate matter, in an attempt to curb these hazardous emissions of CI engines. This paper explores the use of 10% n-butanol/diesel blend in CI engine in order to reduce emissions and effect on engineperformance is also studied. The study focuses on BSFC, BTE, Brake Power (BP), fuel injection equipment wear, NOx, smoke opacity, CO2 emissions characteristics of butanol-diesel blend. Experimental results show that use of butanol-diesel blend in CI engine effectively reduces the NOx, smoke and CO2 emissions. Another key trend observed was reduction of BTE and BP with slight increase in BSFC.
