摘要
从热平衡分析着手，对柴油机燃用柴油和碳酸二甲脂（DMC）混合燃料后缸内传热规律及热效率和动力性进行了研究。研究结果表明：燃用柴油与DMC混合燃料的热平衡与燃用纯柴油相比有所不同，随着DMC在柴油中添加比例的增加，转化为有效功的比例也逐渐增加，当DMC添加比例为15％～20％时，有效功的比例增加3％左右，而冷却水、排气、机油带走热量的比例均有所下降。
Based on the analysis of thermal balance, heat transfer in cylinder, thermal efficiency and power performance of a diesel engine fuelled with DMC-diesel blend fuel were investigated. The results show that the thermal balance of engine fuelled with DMC-diesel blend fuel is different from that fuelled with pure diesel fuel. When DMC proportion increases in blend fuel, the effective power output increases, and when DMC proportion is 15 % to 20 %, the effective power increases by 3 %, while the heat loss in coolant exhaust and lubricating oil decrease to some extent.
