标准摘要
[中文适用范围]： 本文件规定了测量车辆废气排放、电能和燃油消耗的底盘测功机测试程序。 本文件适用于具有以下特征的车辆： ——根据相关地区适用的驾驶考试（ADT）标准中的定义，分类为乘用车或轻型卡车的车辆； ——可充电储能系统（RESS）的标称能量至少占 ADT 总能耗的 2%； ——仅使用液体燃料（例如汽油和柴油）的内燃机（ICE）。 注：对于使用其他燃料[例如压缩天然气（CNG）、液化石油气（LPG）、氢气]的内燃机车辆，本文件可适用，但消耗燃料的测量除外；否则可采用相应燃料的测量方法。 本文件提出了修正混合动力电动汽车 (HEV) 测量的排放和燃料消耗的程序，以便在 RESS 的充电状态 ISOC) 在试验开始和结束之间不保持相同的情况下获得值。 ADT。 当车辆未外部充电且仅在充电维持 (CS) 状态下运行时，它还可应用于可外部充电 HEV 的废气排放和燃料消耗的测量程序，如 ISO 23274-2 中所述。 [外文原描述]： This document specifies a chassis dynamometer test procedure to measure the exhaust emissions and the electric energy and fuel consumption for the vehicles. This document applies to vehicles with the following characteristics: — vehicles classified as passenger cars or light duty trucks, as defined in the relevant regional applicable driving test (ADT) standard; — the nominal energy of the rechargeable energy storage system (RESS) is at least 2 % of the total energy consumption over an ADT; — internal combustion engine (ICE) only using liquid fuels (for example, gasoline and diesel fuel). NOTE In the case of the vehicles with ICE using other fuel [for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), hydrogen], this document can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply. This document proposes procedures for correcting the measured emissions and fuel consumption of hybrid-electric vehicles (HEVs), in order to obtain the values when the state of charge (SOC) of the RESS does not remain the same between the beginning and the end of an ADT. It can also be applied to measurement procedures for exhaust emissions and fuel consumption of externally chargeable HEVs when a vehicle is not externally charged and operated only in the charge sustaining (CS) state, as described in ISO 23274‑2.
