油电混合车,包含插电式油电混合动力车辆的废气排放和节油效率的测定用推荐实施规程

[中文适用范围]： 汽车工程师协会 (SAE) 推荐做法为设计用于公共道路上行驶的混合动力电动汽车 (HEV) 制定了统一的底盘测功机测试程序。该程序提供了测量和计算按照城市测功机驾驶计划 (UDDS) 和高速公路燃油经济性驾驶计划 (HFEDS) 驾驶的混合动力汽车的废气排放和燃油经济性以及按照 US06 驾驶计划驾驶的混合动力汽车的废气排放的说明。时间表 (US06) 和 SC03 驾驶时间表 (SC03)。然而，如果相应的准备程序、测试时长和权重因子进行相应修改，则程序的结构使得其他驾驶时间表可以被替代。此外，该文件没有具体说明要测量哪些排放成分（例如HC、CO、Ndx、CO2）；相反，该决定将取决于测试人员的目标。插电式混合动力汽车 (PHEV) 运行的排放计算作为清单结果提供，其加权方式与燃料和电能消耗相同。在确定认证方法之前，必须首先做出车内排放与车外排放、零排放驾驶的相对优势以及如何最好地权衡电荷消耗 (CD) 模式下的“冷启动”周期的决定。因此，旨在证明 PHEV 符合排放标准的计算或测试方法超出了本文件的范围。出于本测试程序的目的，HEV 被定义为可以从以下两种存储能源中获取推进能量的道路车辆：(1) 消耗性燃料和 (2) 可充电储能系统 (RESS)由车载混合动力推进系统、外部电源或两者充电。本文件涵盖的消耗性燃料仅限于石油基液体燃料（例如汽油和柴油）、醇基液体燃料（例如甲醇和乙醇）和碳氢化合物基气体燃料（例如压缩天然气） ）。本文档涵盖的 RESS 包括电池、电容器和机电飞轮。其中包括用于测试设计为常规非车载充电的混合动力汽车的 CD 操作模式的程序，并提供根据使用中的驾驶统计数据结合 CD 和充电 (CS) 行为的计算。 HEV 的 RESS 标称能量应大于特定测试循环燃料消耗能量的 2%，才有资格按照本文件中包含的程序进行测试。单辊电动测功机测试程序的规定是为了最大限度地减少轨道测试中固有的测试差异，并符合废气排放和燃油经济性测量的标准行业惯例。本文件不包括依赖充电（RD）操作模式或车辆的测试程序（定义见 3.1.2）。本文件不涉及计算调整后的美国环境保护署 (EPA) 标签每加仑英里数 (MPG) 所需的方法或方程（有时称为“EPA 5 循环”计算）。 [外文原描述]： This SAE Recommended Practice establishes uniform chassis dynamometer test procedures for hybrid-electric vehicles (HEVs) and plug-in hybrid-electric vehicles (PHEVs) designed for public roads. This recommended practice provides instructions for measuring and calculating the exhaust emissions and fuel economy of such vehicles over the following standard test cycles: the Urban Dynamometer Driving Schedule (UDDS), the Highway Fuel Economy Driving Schedule (HFEDS), the US06 Driving Schedule (US06), the SC03 Driving Schedule (SC03), and the cold-start Federal Test Procedure (cold FTP), which is based on the UDDS. However, the procedures are structured so that other driving schedules may be substituted, provided that the corresponding preparatory procedures, test lengths, and weighting factors are modified accordingly.This document does not specify which emissions constituents to measure (e.g., HC, CO, NO x , CO 2 ); instead, that decision will depend on the objectives of the tester. The emissions calculations for PHEV operation are provided as inventory results, weighted in the same manner as fuel and electrical energy consumption. Decisions for on-board versus off-board emissions, relative benefits of emissions-free driving, and how best to weight a cold-start cycle in charge-depleting (CD) mode must first be made before a certification methodology can be determined. Thus, calculations or test methodology intended to certify a PHEV for compliance of emissions StandardDetails is beyond the scope of this document.For purposes of this test procedure, an HEV is defined as a road vehicle that can draw propulsion energy from both of the following sources of stored energy: (1) a consumable fuel, and (2) a rechargeable energy storage system (RESS) that is recharged by the on-board hybrid propulsion system, an external electric energy source, or both. Consumable fuels covered by this document are limited to petroleum-based liquid fuels (e.g., gasoline and diesel fuel), alcohol-based liquid fuels (e.g., methanol and ethanol), and hydrocarbon-based gaseous fuels (e.g., compressed natural gas). The RESS is assumed to be an electrochemical battery pack because testing HEVs with capacitors or electromechanical flywheels requires a different approach to tracking energy in and out of the energy storage system. Procedures are included to test CD operating modes of PHEVs, which are designed to be routinely charged off-board, and calculations are provided that combine the CD and CS behavior according to in-use driving statistics.This document does not include test procedures for recharge-dependent (RD) operating modes or vehicles. See Section 3 for the definition of recharge-dependent.This document does not address the methods or equations necessary for calculating the adjusted U.S. Environmental Protection Agency (EPA) miles per gallon (mpg) labels (sometimes referred to as “EPA Five-Cycle” calculations).Cross Reference: 10CFRPart474,2005-01-0685,40CFRPart600,40CFRPart86,J1634_201707,J1715_201410,J2263_202005,J2264_201401,J2841
