Abstract :The aim of the study is to determine the effect of small percentage of methanol into diesel-biodiesel fuel blends. In this context, standard diesel fuel insert ignore into journalissuearticles values(50%);-biodiesel insert ignore into journalissuearticles values(47%);-methanol insert ignore into journalissuearticles values(3%); and diesel insert ignore into journalissuearticles values(50%);-biodiesel insert ignore into journalissuearticles values(44%);-methanol insert ignore into journalissuearticles values(6%); blends were tested in a single cylinder, direct injection diesel engine at full load conditions. Performance and exhaust emission characteristics of engine fuelled with biodiesel-methanol-diesel were compared to the conventional diesel fuel. Break power of the test fuel blends showed a decreasing trend due to their lower heating value. For all blend fuels, brake specific fuel consumption insert ignore into journalissuearticles values(BSFC); values increased as compared diesel fuel. Also, the study indicated that methanol percentage of 6% in test fuels is more effective than that of 3% in terms of reducing of the NOx and CO emissions.
