摘要
为保证车辆等速路试燃料消耗量检测和评价的统一性,应将车辆路试负荷和发动机负荷都校正在标准环境状态下进行燃料消耗量检测和评价。鉴于此,介绍了四种校正方法,并推导四种校正方法的公式。建议不同标准统一采用第四种校正方法,因为该方法不仅会对路试负荷进行校正,也会对发动机克服路试负荷和附件负荷的功率进行校正,同时还分析了前三种方法相对第四种方法的误差。
In order to ensure the uniformity of the measurement and evaluation of fuel consumption of vehi-cle constant-speed road test, the road test load and engine load of vehicle should be corrected to reference state. Given this, this paper introduces four correction methods, gets four formulas, and the fourth correction method is recommended. Because this method can correct not only the road-test load but also the capacity of engine load and accessories load. At the same time, it analyzes the deviation between the first three correction methods and the fourth one.
