Experimental studies on a diesel engine fueled with wood pyrolysis oil diesel emulsions.

摘要: Abstract — This paper describes the combustion, performance and emission parameters of a diesel engine fueled by wood pyrolysis oil (WPO) emulsion with Diethyl ether (DEE) as an ignition improver. Experimental studies were carried out in single cylinder, four stroke, air cooled, DI three fuels that WPO emulsion, emulsions addition 2% 4% DEE. The results compared fuel data, analysed it is presented paper. brake thermal efficiency found to be higher 6.34, 9.5 9.3 percentages for DEE respectively when at full load. percentage reduction NO emissions about 19.21, 28.38 34.81 noticed above said fuels. Index Terms Diesel engine, emission, improvers, performance, pyrolysis, surfactant . I. I NTRODUCTIONMany alternative compression engines introduced last two decades replacement fuel. Liquid from biomass has great scope especially agriculture based countries developing countries. than up 30% beyond that, increased. Biomass can converted into useful energy adopting different techniques such dry anaerobic digestion, bio photolysis, liquefaction, gasification, hydrolysis solvent extraction [1]. Out this, few advantages simple low pressure operation, negligible waste product high conversion order 83%. Pyrolysis decomposition process substances absence oxygen or little presence oxygen. may yield solid, liquid gaseous products [2]. resources used production includes wide range materials forest residues, crops, organic wastes,
