Effects of Ethanol-n butanol-diesel Oxygenated Fuel on Performance of Diesel Engine

Abstract:

The experiments of the economy performance and emissions of diesel engine fueled with ethanol-n butanol-diesel were performed on a dual-cylinder direct injection diesel engine. The results show that without modification on the engine, while the mixed proportion of ethanol getting larger, the equivalent brake specific fuel consumption decreases and effective thermal efficiency increases when the diesel engine work on medium and high loads condition, NO_X emissions and smoke decreased obviously. But the smoke increased when the proportion of ethanol is 20%. And the results also indicate that it is beneficial for decreasing the smoke and NO_X emissions to reduce suitably fuel supply advance angle when the diesel engine fueled with blend fuel mixed high proportion of ethanol.
