本SAE推荐实施规程中概述的测试技术是作为测试和评估重型卡车和公共汽车燃料消耗总体计划的一部分而开发的。本文件中概述的技术提供了确定这些发动机驱动部件功耗所需的设备和设施类型的一般说明。建议在特定车辆操作的实际数据基础上仔细审查整个测试中建议的特定操作条件。如果特定车辆应用尚不清楚，请参见SAE J1343。

The testing techniques outlined in this SAE Recommended Practice were developed as part of an overall program tor testing and evaluating fuel consumption of heavy duty trucks and buses. The technique outlined in this document provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components.It is recommended that the specific operating conditions suggested throughout the test be carefully reviewed on the basis of actual data obtained on the specific vehicle operation.If specific vehicle application is not known, see SAE J1343.
