Abstract :Current study uses DieselFX insert ignore into journalissuearticles values(DFX); additive to increase the cetane number of the diesel fuel used in compression-ignition insert ignore into journalissuearticles values(CI); engines, re-duce carbon monoxide insert ignore into journalissuearticles values(CO); and hydrocarbon insert ignore into journalissuearticles values(HC); emissions, and im-prove engine performance. In this respect, the effects of the additive used in diesel engines were analyzed. A Katana brand, KM 178 FE model, sin-gle-cylinder, air-cooled engine was started at a constant engine speed with different loads for the experiments. By adding the additive in 1% and 2% ratios the cetane number was increased to 62 and 75, respective-ly, furthermore at 3% and 5% additive ratios the cetane number value reached over 76. In result of the experiments, DFX2 offers 12.24% in-crease on efficiency compared to the diesel fuel and 6.87% increase in specific fuel consumption. As for the emission values, with the use of DFX5 44.23% reduction in HC emission and 50% reduction on average in CO emission was observed at 3000W load compared to additive-free diesel fuel. Moreover, 37.84% increase was observed in carbon dioxide insert ignore into journalissuearticles values(CO2); emission at 3000W engine load for DFX2 whereas 52.11% in-crease was observed in nitrogen oxide insert ignore into journalissuearticles values(NOx); emission for DFX5.
