A Review on Effects of Blends containing Low Ratios of Alternate Fuels - Biodiesel on Diesel Engine Performance and Exhaust Emissions

Abstract

Emissions from diesel engines are considered to be contributing greatly to air pollution. The major pollutants released are nitrogen oxide, carbon monoxide, unburnt hydrocarbon emissions and smoke. A solution to these have been viewed in the domain of fuel-related techniques wherein number of alternatives are tested. The test can be done running engine on 100% alternative fuel or blending alternate fuel with diesel. With a view to compare the various alternatives and choose the most appropriate one, the present paper deals with results obtained with four alternatives viz. (a) Blending diesel with Ethanol (b) Blending diesel with Butanol (c) Blending diesel with vegetable oil (d) Test on 100% Biodiesel. (Methyl Ester of Mahua Oil, referred in the paper as MOME). The results are focused on emission characteristics and brake specific fuel consumption for the engine.
