摘　　要：碳酸二甲酯(DMC)具有含氧量高、沸点低、与柴油互溶性好等特点,适合作为柴油机的燃料添加剂。在轻型直喷式柴油机上对柴油机燃用柴油和碳酸二甲脂混合燃料后,柴油机的燃烧特性、传热特性、排放特性进行了研究。结果表明:燃用柴油和碳酸二甲酯混合燃料后,柴油机的碳烟排放大幅度下降,缸内辐射传热量减少,热效率提高。Dimethyl carbonate（DMC） is one of the best fuel additives for diesel engines due to its features such as higher oxygen content＇lower boiling point and better intersolubility with diesel oil. An experimental investigation on combustion, heat transfer and emissions characteristics was performed on a light duty DI diesel engine fueled with diesel oil-DMC blend. The results show that when the diesel engine is fueled with diesel oil-DMC blend, smoke emissions greatly reduce, thermal radiant flux in the cylinder decreases and thermal efficiency increases.
