【摘要】 本文针对当前燃油消耗量测试方法结果单一且可分析性差的问题,根据电喷发动机的工作原理,建立汽车油耗测试系统。系统采用LabVIEW软件设计的人性化界面,具有重用性强、开放性和可扩充性好、开发周期短的特点,可实现对汽车经济性的评价,包括百公里油耗的显示,并与汽车的实时车速联系起来绘制不同工况下的等速百公里油耗曲线,进而分析汽车的燃油经济特性。更多还原

【Abstract】 According to the theory of EFI, we set up a fuel consumption testing system to improvethe current testing methods. The system is based on LabVIEW, has the features of flexibility, openness and short development cycle, can valuate the automobile fuel economy including the display of fuel consumption per 100km curve of equal velocity.更多还原
