油耗测试程序（工程方法）

[中文适用范围]： 本文件描述了一种燃油消耗测试程序，该程序利用行业认可的数据收集和统计分析方法来确定车辆总重超过 10000 磅的车辆之间的燃油消耗差异。该测试程序可用于评估两个或多个不同的车辆，但不能用于评估组件更改。尽管允许进行道路测试，但轨道测试是首选方法，因为它最有可能最大限度地减少天气和交通对结果变化的影响。所有测试均应根据本程序中描述的天气限制进行，并应得到收集的数据和分析的支持。本文件提供的信息可与 SAE 建议实践 SAE J1264、SAE J1252、SAE J1321 和 SAE J2966 以及其他当前和未来的空气动力学和车辆性能 SAE 标准一起使用。 [外文原描述]： This document describes a fuel-consumption test procedure that utilizes industry accepted data collection and statistical analysis methods to determine the difference in fuel consumption between vehicles with a gross vehicle weight of more than 10000 pounds. This test procedure can be used for an evaluation of two or more different vehicles but is not to be used to evaluate a component change. Although on-road testing is allowed, track testing is the preferred method because it has the greatest opportunity to minimize weather and traffic influences on the variability of the results. All tests shall be conducted in accordance with the weather constraints described within this procedure and shall be supported by collected data and analysis. This document provides information that may be used in concert with SAE Recommended Practices SAE J1264, SAE J1252, SAE J1321, and SAE J2966, as well as additional current and future aerodynamic and vehicle performance SAE StandardDetails.Cross Reference: 2009-01-1605,810025,J1252,J1263,J1264,J1321_202010,J1594,J2084_201604,J2263_202005,J2711_201807,J2881_201910,J2966_201704
