Some Aspects of Compression Ignition Engine Performances Using n-Butanol-Diesel Mixtures

Abstract

The biofuels are playing identical prominent activities in solving the green house issues and providing an effective alternatives green energy origin. Alcohol is one of the promising and significant biofuel source used in internal combustion engines in general and in diesel engines in particular. The famous ethanol and methanol has solubility difficulties problem with net diesel when mixture is formed. Butanol C4H10O or C4H9OH is an alcoholic compound has a good soluble in diesel and has bio source. In this work, performances of compression ignition engine using bio n-butanol-diesel mixtures as a fuel is implemented. The 5%, 10%, 20%, and 30% of n-butanol-diesel mixtures by volume are examined as supplementary fuel for diesel engine.The results are showed a stable solubility of n-butanol-diesel mixture. Also, the mixture has 20% n-butanol is optimum blend. It is observed that at 20% n-butanol and 80% diesel, the engine efficiency increased by 6.6% at full load. The carbon dioxide is reduced by 28% and nitrogen oxides are increased by 3% unfortunately.
