摘　　要：高效发动机在节省燃油和使用成本的同时通常伴随生产成本提高。本文针对PHEV发动机热效率对使用成本影响问题,分别在法规标准工况以及综合考虑实际单日出行里程、环境温度和实际行驶因素的用户实际使用工况下,进行使用成本进行分析。结果表明,对于业内两种不同典型热效率水平的发动机,在法规标准工况下每10万km使用成本差异为120-315元,在实际用户工况下每10万km使用成本差异为145-359元。主机厂在发展高效发动机时,可参考本文使用成本变化合理控制生产成本增量。Effi cient engines usually increase production costs while saving fuel and use costs.Aiming at the impact of PHEV engine thermal effi ciency,the use cost under the regulatory standard working conditions and the actual user operating conditions considering the actual daily travel mileage,ambient temperature and actual driving conditions is analyzed in this paper.The results show that for the two engines with diff erent typical thermal effi ciency levels in the industry,the diff erence in use cost per 100,000 km is 120-315 yuan under standard operating conditions,and the diff erence in use cost per 100,000 km under actual user working conditions is 145-359 yuan.Automobile manufacturers should reasonably control production cost increment with reference to changes in operating costs while developing high effi ciency engines.
