摘　　要：从柴油机缸内传热着手,对柴油机燃用柴油和DMC(碳酸二甲酯)混合燃料后,柴油机缸内传热规律及热效率进行了研究。研究结果表明:燃用柴油和DMC混合燃料后,柴油机缸内燃烧改善和炭烟生成量的减少,导致缸内辐射传热量及传热损失减少,柴油机热效率提高。Based on the in-cylinder heat transfer of a diesel engine,a study on the heat transfer in cylinder,thermal efficiency of a diesel engine operating on DMC-diesel blended fuel were carried out. The results showed that combustion and smoke emission were improved; the thermal radiation and heat transfer loss were reduced; and thermal efficiency was improved.
