Evaluation of Performance and Emission parameters of a CI engine fuelled with Palm Styrene, Sun Flower and Rice Bran Methyl Esters Blends Blended with Diesel

This Paper deals with the study of the potential substitution of Palm Styrene methyl ester, Sun
flower methyl ester and Rice bran methyl ester blends for diesel as fuel for automobiles and other industrial
purposes. Biodiesel was prepared from the edible Palm Styrene oil , Sun flower oil and Rice bran oil by
transesterification of the crude oil with methanol in the presence of NaOH or KOH as catalyst.
The objective of this study is the analysis of the performance and emission characteristics of the
Biodiesel that is mixing of equal proportion of three methyl esters are Palm Styrene methyl ester, Sun flower
methyl ester and Rice bran methyl ester (PSME+SFME+RBME) Mixture of methyl ester (MME) in equal
proportion and comparing with petroleum diesel. The tests were carried out on a 4.4 KW, single cylinder,
direct injection, air-cooled diesel engine. Engine tests have been carried out with the aim of obtaining
comparative measures of Brake power, specific fuel consumption and emissions such as CO2, CO, HC, and NOx
to evaluate and compute the behavior of the diesel engine.
