ABSTRACT
In this study and analysis, the physical properties such as calorific value, viscosity, flash, and fire point temperatures of rice bran oil methyl ester were found. The rice bran oil biodiesel has been prepared by transesterification process from pure rice bran oil in the presence of methanol and NaOH. Moreover, property enhancement of rice bran oil methyl ester was also made by adding different additives such as ethanol in various proportions. Rice bran oil methyl ester with 1, 3, and 5% ethanol were analyzed for its fuel properties. The effects of diesel-B20ROME blends with ethanol additive of 1, 3, and 5% on a compression ignition engine were examined considering its emissions. It is found that the increase in biodiesel concentration in the fuel blend influences CO2 and NOx emissions. On the other hand CO and HC emissions are reduced. It is interesting to observe the emission as ethanol-B20ROME blends, reduces CO2 and NOx which are the major contributors to global warming. As the NOx and CO2 can be reduced drastically by the proposed blends, the global warming can be reduced considerably.
