摘要
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NOx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 NOx emission of compression‐ignition engine ,and the effects of retarding fuel delivery timing on NOx emission and performance of engine fueled with biodiesel are investigated through experiments .The experimental results show that , retarding fuel delivery timing can reduce NOx 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 .
