标准范围

本文件规定了汽化器/压力调节器的一般要求,汽化器/压力调节器是液化石油气燃料的一个组成部分,用于ISO?3833中定义的机动车类型。它还提供了一般设计原则,并规定了说明和标记的要求。本文件适用于根据ISO?9162使用气体燃料的车辆(单燃料、双燃料或双燃料应用)。它不适用于以下情况:a) 燃料容器;b) 固定式燃气发动机;c) 集装箱安装硬件;d) 电子燃料管理;e) 加油容器。我们认识到,本文中未具体说明的其他部件可以检查是否符合ISO?20766系列任何适用部分的标准,包括进行适当的功能测试。除非另有规定,否则本文件中提及的所有压力均视为表压。本文件适用于工作压力在110千帕(20摄氏度富含丁烷)和840千帕(20摄氏度丙烷)范围内的装置,以下简称本文件。通过适当的系数(比率)调整压力,可以调节其他工作压力。

This document specifies general requirements for the vaporizer/pressure regulator, a component of liquefied petroleum gas fuel, intended for use on the types of motor vehicles as defined in ISO 3833. It also provides general design principles and specifies requirements for instructions and marking.This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using gaseous fuels in accordance with ISO 9162. It is not applicable to the following:a) fuel containers;b) stationary gas engines;c) container mounting hardware;d) electronic fuel management;e) refuelling receptacles.It is recognized that miscellaneous components not specifically addressed herein can be examined for compliance with the criteria of any applicable part of the ISO 20766 series, including testing to the appropriate functional tests.All references to pressure in this document are considered gauge pressures unless otherwise specified.This document applies to devices which have a service pressure in the range of 110 kPa (butane rich at 20 °C) and 840 kPa (propane at 20 °C), hereinafter referred to in this document. Other service pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio).
