Abstract

Current study uses DieselFX (DFX) additive to increase the cetane number of the diesel fuel used in compression-ignition (CI) engines, re-duce carbon monoxide (CO) and hydrocarbon (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 (CO2) emission at 3000W engine load for DFX2 whereas 52.11% in-crease was observed in nitrogen oxide (NOx) emission for DFX5.
