摘　　要：随着轻型商用车第四阶段燃料消耗量(简称油耗)限值标准的实施,以及新能源车型逐步进入市场,传统发动机厂商迎来巨大挑战。通过一维整车性能仿真,以目前市场在售轻型商用车及主流水平的发动机为研究对象,预测针对不同整车参数和发动机性能参数的全球统一轻型车辆测试循环(WLTC)油耗,结果表明现有发动机性能可以满足部分车型第四阶段油耗标准。The four-stage fuel consumption limit of light commercial vehicles is about to be implemented,and new energy vehicles be⁃ing gradually entering the market,the traditional internal combustion engine is facing great challenges.It predicts the WLTC cycle fuel consumption under different vehicle parameters and engine performance parameters through one-dimensional vehicle performance simulation,taken the light commercial vehicles and mainstream level internal combustion engines which sold in current market as the research object,the results show that the on sale engine performance can meet the four-stage fuel consumption of some models.
