11、274-1:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject f

12、or which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on

13、 all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are

14、 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held res

16、ised.ISO 23274 consists of the following parts, under the general title Hybrid-electric road vehicles Exhaust emissions and fuel consumption measurements: Part 1: Non-externally chargeable vehicles Part 2: Externally chargeable vehiclesiv ISO 2013 All rights reservedBS ISO 23274-1:2013INTERNATIONAL

17、STANDARD ISO 23274-1:2013(E)Hybrid-electric road vehicles Exhaust emissions and fuel consumption measurements Part 1: Non-externally chargeable vehicles1 ScopeThis part of ISO 23274 specifies a chassis dynamometer test procedure to measure the exhaust emissions and the electric energy and fuel consu

18、mption for the vehicles.This part of ISO 23274 applies to vehicles with the following characteristics: the vehicle is classified as passenger cars or light duty trucks, as defined in each regional annex; the nominal energy of the rechargeable energy storage system (RESS) is at least 2 % of the total

19、 energy consumption over an applicable driving test (ADT); internal combustion engine (ICE) only using liquid fuels (for example, gasoline and diesel fuel).NOTE 1 In the case of the vehicles with ICE using other fuel for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), hydrogen,

20、 this part of ISO 23274 can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.This part of ISO 23274 proposes procedures for correcting the measured emissions and fuel consumption of hybrid electric vehicles (HEVs), in or

21、der to obtain the values when the battery 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

22、charged and operated only in the charge sustaining (CS) state, as described in ISO 23274-2.NOTE 2 For CS state, see ISO 23274-2.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
