摘　　要：研究了碳酸二甲酯(DMC)添加比例对柴油机性能的影响。结果表明,随着燃料中DMC掺混比例的增加,有效热效率增加,功率降低。在同一工况下,发动机排气烟度随DMC的加入而降低,NOx无明显上升,CO排放也随着DMC的增加而降低。Experimental study on a direct injection diesel engine was carried out to investigate the effects of dimethyl carbonate （DMC）as oxygenate additive to diesel fuel on the performance of diesel engine. The results show that the power is decreased and the thermal efficiency will increase with the increase of dimethyl carbonate（DMC）fraction in the blends, for the same brake mean effective pressure, the exhaust smoke and CO decrease with the increase of DMC fraction in the blends while NOx shows little variation with the addition of DMC in diesel fuel.
