汽油燃料注入系统用电动燃料泵的确认试验

[中文适用范围]： 本SAE推荐规程定义了泵特性的三个基本类别的测试。这些是基本功能性能测试、泵限制测试和泵完整性测试。基本功能测试包括三个单独测试，第一个是泵速、电流消耗和电阻。其他两个单独测试是在额定输送压力和电压下的死头压力和输送燃料流量。泵限制的测试包括热燃料处理、冷磁击倒、负载转储瞬态、电气干扰和反向流动泄漏的单独测试。泵完整性的测试包括振动、温度循环、内部流体兼容性和操作耐久性的单独测试。这12个单独测试提供了特定泵的特性描述。本文件仅涉及油箱安装的电动机驱动的低压燃料泵本身，不涉及油箱泵模块，因为这些模块可能包括其他设备。要测试的泵适用于燃料喷射、火花点火发动机的液体燃料泵送。 [外文原描述]： This SAE Recommended Practice defines the tests for three basic categories of pump characteristics. These are the basic functional performance tests, the pump limitation tests and the pump integrity tests. The basic functional tests included are three individual tests, with the first being for pump speed, current draw, and electrical resistance. The other two individual tests are for the deadhead pressure and the delivered fuel flow rate at the rated delivery pressure and voltage. The included tests for pump limitations are individual tests for hot fuel handling, cold magnet knockdown, load dump transient, electrical interference, and reverse flow leak. The testing for pump integrity includes individual tests for vibration, temperature cycling, internal fluid compatibility, and operational durability. These 12 individual tests provide a characterization of the particular pump. This document only addresses the in-tank-mounted, electric-motor-driven, low-pressure fuel pump itself, and does not address in-tank pump modules, as these modules may include other devices. The pumps that are to be tested are intended for the pumping of liquid fuels that are applicable to fuel-injected, spark-ignition engines.Cross Reference: J1113
