摘　　要：从柴油机缸内传热着手，对柴油机燃用柴油和DMC（碳酸二甲脂）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碳烟生成量减少．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 cylinder heat transfer of a diesel engine, this paper conducts a study on the heat transfer in cylinder, thermal efficiency of a diesel engine operating on DMC-diesel blend fuel was carried out results showed that combustion and smoke emission were improved, the thermal radiation and heat transfer The loss were reduced and thermal efficiency was improved.
