[中文适用范围]： 该 SAE 推荐做法促进了对汽油发动机应用中使用的燃油压力调节器和压力阻尼器进行的评估和鉴定测试的一致性。其范围仅限于供油压力低于 1000 kPa 的汽车端口和节气门体燃油喷射系统中使用的燃油压力调节器和阻尼器。它进一步限于台架类型测试。更具体地说，本文档旨在用作以下内容的指南：识别并定义用于测量燃油压力调节器和压力阻尼器性能特性的参数。本文档中包含的参数有： 1. 斜率 2. 工作流量范围 3. 重复性 4. 迟滞 5. 动态响应建立测试程序并推荐测试设备和方法来测量和量化这些参数。 C。建立测试程序和推荐的测试设备和方法，以量化组件整个生命周期内的模拟现场可靠性。 d.标准化与燃油喷射系统的燃油压力调节和压力阻尼相关的术语。 e.除非另有说明，否则记录单个零件的测试结果。在报告群体特征时，必须明确说明@样本大小@选择方法@和分析技术。 [外文原描述]： This SAE Recommended Practice promotes uniformity in the evaluation and qualification tests conducted on fuel pressure regulators and pressure dampers used in gasoline engine applications. Its scope is limited to fuel pressure regulators and dampers used in automotive port and throttle body fuel injection systems where fuel supply pressure is below 1000 kPa. It is further restricted to bench type tests. More specifically, this document is intended for use as a guide to the following:aIdentify and define those parameters that are used to measure fuel pressure regulator and pressure damper characteristics of performance. The parameters included in this document are:1Slope2Operating Flow Range3Repeatability4Hysteresis5Dynamic ResponsebEstablish test procedures and recommend test equipment and methods to measure and quantify these parameters.cEstablish test procedures and recommend test equipment and methods to quantify simulated field reliability over the life of the component.dStandardize the nomenclature as related to fuel pressure regulation and pressure damping for fuel injection systems.eExcept where stated, test results are recorded for individual parts. Where population characteristics are reported, the sample size, selection method, and analysis technique must be explicitly stated.Cross Reference: ASTMB117,ASTMD1266,ASTMD128,ASTMD1298,ASTMD1319,ASTMD1744,ASTMD2699,ASTMD323,ASTMD3231,ASTMD3237,ASTMD445,ASTMD471,ASTMD56,ASTMD86,ASTMD893,J1541,J306_201708,J308_202205,J310_202005,J313_201706,J814_201307
