Abstract—This paper describes the combustion, performance and emission parameters of a diesel engine fueled by wood pyrolysis oil (WPO) diesel emulsion with Diethyl ether (DEE) as an ignition improver. Experimental studies were carried out in a single cylinder, four stroke, air cooled, and DI diesel engine with three fuels that were WPO diesel emulsion, WPO diesel emulsions with addition of 2% and 4% DEE. The results were compared with the diesel fuel data, analysed and it is presented in the paper. The brake thermal efficiency is found to be higher by 6.34, 9.5 and 9.3 percentages for WPO diesel emulsion, WPO diesel emulsions with 2% and 4% DEE respectively when compared with diesel fuel at full load. The percentage reduction in NO emissions of about 19.21, 28.38 and 34.81 were noticed for the above said fuels.
