Emission and Combustion Characteristics of Biodiesel with Dee Additive and Thermal Barrier Coated Piston

Abstract

Continuous emissions of green house gases like carbon dioxide by industries and automobiles in atmosphere is increasing day by day and if not checked and regulated may bring disasters to human life. The existence and continuation of human life will be at risk. All technocrats, engineers and environmentalists have to work together for designing engineering systems and especially automobiles for combustion of fuels especially biodiesel which reduces emission of green house gases. Also there is a requirement of biodiesels to be renewable and obtained from biomass. The methyl ester produced from algae is used as a source of energy and is tested for its suitability in a variable compression ratio diesel engine (VCR). Blend B20 is added with 10% diethyl ether and tested for its combustion and emission characteristics with 200 micron zirconia coated piston. Improvement in performance is observed in comparison to the characteristics obtained with only coated piston and without additive.
