The main problem is the very low cetane rating of alcohol which makes ignition by compression difficult. A dual injection method has been selected as the best compromise. A single cylinder idi diesel engine with 0.78 Liter displacement and a compression ratio of 19:1 was used. The original injection system was used for diesel fuel and ethanol was injected into the precombustion chamber directly through a single hole nozzle. The experimental results show that ethanol- diesel fuel dual injection method has the same performance and emission characteristics as the pure diesel operation. However, the smoke level at high load is considerably lower than that of conventional diesel engines. A conventional diesel engine can be easily converted to an alcohol- diesel engine and restored to the original. Alcohol is not suitable for diesel engines because of its poor self- ignition characteristics, however, applying the fuel supply techniques for instance dual injection method, it could be the future fuel of diesel engines (a).Read More
