Research on Performance and Emissions of Diesel Engine Fueled with Diesohol

The experiments of the performance and emissions of diesel engine fueled with diesohol were performed on ZS1100 diesel engine. Two blend fuels consisted of 15% ethanol, 835% diesel and 15% solublizer (by volume) were evaluated :one without cetane number improver and one with a cetane number improver. The engine performance parameters and emissions including fuel consumption, exhaust temperature, Bosch smoke number, CO, NOx, and THC were measured, and compared to the baseline diesel fuel. The results show that the brake specific fuel consumption increased at overall engine operating conditions, but it is worth noting that the brake thermal efficiency (BTE) increased by up to 1%～2% with two blends when compared to diesel fuel. The engine fueled with ethanoldiesel blend fuels has higher emissions of THC, lower emissions of CO, NOx, and smoke. And the results also indicate that the cetane number improver has positive effect on CO and NOx emissions, but negative effect on THC emission. 
