The purpose of this study, in a diesel engine, diesel oil and hackberry investigate the effects on engine performance using mixtures. Refined hackberry oil through transesterification obtained with the method and biodiesel called hackberry biodiesel of (ÇYBD) is a diesel engine performance characteristics obtained through the use of the engine changes in emissions were evaluated and compared with Diesel fuel. Oil methyl ester was converted into hackberry made in this study and 60% by volume is mixed with the diesel fuel. made in short-term experiments hackberry oil methyl ester and is used without a problem in diesel fuel as an alternative fuel mixture.
