A new type of oxygenated fuel blend was designed, it was diesel-fuel mixed with 15%、25% n-butoxyether(NBE) in volume. The experiments were conducted on a TY1100 single cylinder DI diesel engine. When the diesel engine rotational speed was 1400r/min and 2000r/min，the effects of the oxygenated fuel blends on engine Combustion and emission characteristics were studied. Results of experiment show that NBE has good solubility in diesel. When the diesel engine without any modification fueled with 15% ~ 25% NBE-diesel blended fuel，in comparison to original diesel engine, the diesel engine dynamic changes little, auto-ignition period is delay, and the premix combustion period increases, while the diffusive combustion period and combustion duration decreases. At high load, the peak values of cylinder pressure, pressure increase rate decrease strongly, but at low load, the peak values decrease slightly. In the same operating condition, the diesel engine fueled with 15% ~ 25% NBE-diesel blended fuel, its smoke, CO, HC and NOx emission decreases with the increasing content of NBE, can significantly reduce the smoke emission and reduce CO、HC and NOx emissions in some extent. For the largest decline amplitude, smoke emission decreases to 75%, CO emission decreases to 56%, HC emission decreases to 76.9%, and NOx emission decreases slightly, it decreases 13.1%.
