Ignition analysis on neat alcohols and biodiesel blends propelled research compression ignition engine

ABSTRACT

In this present study, the emissions and performance characteristics of four-stroke, single-cylinder, water-cooled, diesel engine fueled with different blends of Rice bran biodiesel and octanol blends i.e. RBD100, RBD90O10 (10% Volume of octanol dispersed in RBD100) and RBD80O20 (20% Volume of octanol dispersed in RBD100) at 1800 rpm for compression ratio 17.5:1 were investigated. The transesterification process was used for biodiesel production with the presence of the alkaline catalyst (KOH) and methanol. The optimum biodiesel yield was found to be 88%. The fuel properties of the blends were found to be within the ASTM limits. Experimental results revealed that BTE increased and BSFC decreased with octanol addition to rice bran biodiesel. Furthermore, the diesel engine fueled with octanol and biodiesel blends reduced the NOx, Smoke, HC, CO emission due to the higher latent heat of vaporization and improved chemical properties.

KEYWORDS:
