货车和公共汽车用液压泵耗能量测量的试验方法

[中文适用范围]： 本文件涵盖了用于确定重型卡车和公共汽车上使用的液压泵的功耗特性的评估技术。本 SAE 推荐实践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油消耗的总体计划的一部分而开发的。本文件中概述的技术提供了对要运行的测试的描述，以确定这些发动机驱动部件的功耗，执行这些测试通常所需的设备和设施的类型在 SAE J 745 中讨论。建议具体操作条件建议 [外文原描述]： This document covers evaluation techniques for determining the power consumption characteristics of engine driven hydraulic pumps used on heavy-duty trucks and buses. The testing technique outlined in this SAE Recommended Practice was developed as part of an overall program for testing and evaluating fuel consumption of heavy-duty trucks and buses. The technique outlined in this document provides a description of the test to be run to determine power consumption of these engine driven components, the type of equipment and facilities which are generally required to perform these tests are discussed in SAE J745. 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.Cross Reference: J745_201911
