推迟供油是一种有效降低柴油机NOx 排放的方法，研究推迟供油对生物柴油发动机性能和NOx 排放的影响。实验结果表明：推迟供油可明显降低生物柴油发动机NO x 排放，而动力性和经济性略有降低；对于实验发动机，推迟2°CA供油提前角，可在降低NOx 排放的同时降低碳烟排放。

Retarding fuel delivery timing is an effective method to reduce NO x emission of compression‐ignition engine ,and the effects of retarding fuel delivery timing on NO x emission and performance of engine fueled with biodiesel are investigated through experiments .The experimental results show that , retarding fuel delivery timing can reduce NO x emission significantly and worsen the power and fuel economy slightly ,meanwhile when the fuel delivery advance angle is retarded for 2°CA ,the soot emission reduced .
