EPPR-11-07e India proposal on EPPR-10-14e The deletions are struck through like this and additions are in this font No Section Para 1 General Cate gory and refer ence to SR1. Proposed changes Justification India and IMMA had suggested use of the categorization as per SR1. However, EC reservation to refer classification reference numbers laid down in SR1 (3-1, 3-3, etc) owing to incompatibility with regional vehicle classification. Should be re-discussed after revision of SR1 is agreed on. Expressions like Motorcycle, two wheeled motorcycle, three wheeled vehicle, tricycle are generic terms. It is necessary to define them clearly in the regulation. Since finalization of the amendment to SR1 will take time, it is very likely that this draft GTR will get delayed. In order to avoid this delay India suggests the following: 1. Proceed the current GTR work taking into account the current definitions in SR1 which are also referred in other GTR’s. 2. Build in clauses in text of GTR to provide freedom for Contracting Parties to make the applicability to suit the local definition in GTR. These proposals are contained in Sr. No. 2,3,11,12 and Table 3.6-1 item no 1.1. 2 B.1 2. Scope Two- [and three-]wheeled vehicles of [category 3-1, 3-3 and 3-2, 3-4, 3-5] as defined in S.R. 1, concerning the common definitions of vehicle categories, masses and dimensions document TRANS/WP29/1045e, as amended by ECE/TRANS/WP29/1045/Amend.1, equipped with a PI engine in accordance with Based on comments at Sl. No.1 above, all the square brackets may be removed and reference to SR 1 be incorporated table B.1.-1. 1/16 EPPR-11-07e No Section Para Proposed Justification changes 3 B.1 Table Modify the table 1-1 as indicated below. 1. Exemption for gas fuel vehicles with a small petrol tank capacity: India had proposed addition of a sentence to exempt bi-fuel vehicles with a small petrol tank ( < 2 litre/3 litre) in the scope. Later it was agreed that a definition for a mono-fuel gaseous vehicle can be incorporated. However, certain difficulties have cropped up for evolving this definition. It would take some time to evolve this definition India now suggests that requirement of exemption may be built into the table so that this document can be finalized. As and when the definition is finalized, (which can be built into GTR 2 Rev 1), this document can be amended suitably. 2. Hybrid vehicles It was agreed in the 10th EPPR session that the Hybrid vehicles will be considered at a later stage. Hence it is necessary to remove the hybrid vehicles from this table also. Vehicles with CI engines including hybrids MonoFlex-fuel fuel Vehicle with PI engines including hybrids Mono-fuel Petrol Flex-fuel Bi-fuel* LP G NG/ Biomethane Petrol Petrol Petrol Petrol NG/ Biomethane Diesel LPG NG/ Biomethane H2 Ethanol (E85) H2NG Biodiesel H2 Diesel Pure electric vehicle or vehicle propelled with compressed air (CA) Hydrogen Fuel cell vehicle Type III test Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes No No Type IV test Yes No No No Yes (petrol only) * Yes (petrol only) * Yes (petrol only) * Yes (petrol only) * No No No No No * Type IV test is not applicable for motor vehicle that is designed primarily for permanent running on LPG or NG / bio-methane or hydrogen, having a petrol system, with petrol tank capacity not exceeding 2 litres in the case of a 3-1, 3-3 and 3-4 category vehicle and not exceeding 3 litres in the case of a 3-2 and 3-5 category vehicles, intended for emergency purposes or starting only. Table B.1.-1: Scope with regard to the propulsion unit 2/16 EPPR-11-07e No Section Para 4 B.1 3.5. Proposed changes Justification ‘fuel storage system’ means a type of energy storage system that stores [chemical] energy carriers and which is refillable the liquid fuel; This GTR is for evaporative emissions and is relevant only to liquid fuels. While a more generic definition may be needed in other GTR (e.g. GTR 2 Revision 1), it is suggested that reference to liquid fuel is good enough to complete this definitions in this document. 5 B.1 3.7, 3.8, 3.10 and 3.11 These definitions may be deleted These terms relate to hybrid vehicles. Now that the hybrid vehicles are out of scope of this GTR, these can be deleted. These definitions can be added in GTR 2 Rev.1 appropriately 6 B.1 3.16 This definition may be deleted The definition as it is worded currently does not serve the intended purpose, since the limitation of the petrol tank capacity is not included. Alternate method of taking care of this is suggested by amending the table 1-1 as suggested at sl. No. 3. ‘Mono-fuel gaseous vehicle’ means a vehicle that is designed primarily for permanent running on LPG or NG / bio methane or hydrogen, but may also have a petrol system for emergency purposes or starting only, 7 B.1 3.## New definition to be added: "useful life" means the relevant period of distance and/or time over which the vehicle comply with the detailed technical requirements specified in this GTR when the vehicle is used normally and maintained according to the prescriptions of the manufacturer. Since the expression useful life is used in the document, India feels that it is better to define the terms. The phraseology is selected from the details given in document EPPR 10-15e. It will be necessary to use the same term while preparing the GTR for the Type V test also. 3/16 EPPR-11-07e No Section Para Proposed changes Justification 8 B.2 Foot note 1 The Type III test procedure to be conducted in accordance with the requirements to be agreed upon by the UN EPPR informal working group and to be supplemented in subsequent amendment No 1 to this GTR. 1. India agrees with the proposal to delete para 2.1.2 and prescribe its contents in the foot note. 2. An editorial correction is suggested in foot note. Necessity may come to issue amendments prior to finalization of the crank case emission test procedure. Hence using the expression “amendment No.1” could lead to operational difficulties. 9 B.2 2.2. The manufacturer shall provide [the approval authority of the Contracting party or its designated agency] with technical details and drawings to prove that the engine or engines are so constructed as to prevent vapour of any fuel, lubrication oil or crankcase gases from escaping to the atmosphere from the crankcase gas ventilation system. Expressions “approval authority”, “technical services”, certification etc. are used differently at different places generally with the same intention. Some terms (e.g. Techinical Service”) are not used in India. India suggests to use the expression “approval authority of the Contracting Party or its designated agencies” at all places to avoid difficulties later. A Physical verification may be conducted that the crankcase breather is not let out into atmosphere. 10 B.3. 2.1. The vehicle manufacturer shall prove [to the approval authority of the Contracting party or its designated agency technical service and to the satisfaction of the approval authority] that the fuel storage and supply system are leaktight in accordance with point 2.2. 11 B.3 2.4.2 A two-wheeled motorcycle, [a motorcycle with sidecar and a tricycle] of Category 3-3, 3-4 and three wheeled vehicle of category 3-5 1. See serial No. 9 2. The current wording also leads to wrong understanding that the demonstration has to be done twice, once to technical services and again to the certifying agency.

The need to give freedom for CPs to make use of their national/regional classification has been built in. India believes that this could address the concerns of EC. This can be reviewed and corrected later, once the changes in SR 1 are finalized by WP29/AC3. 13 B.3 2.5 14 B.3 2.5.1 The appropriate test fuel, as defined in Annex 2 of GTR No 2 (for E0) and Annex XX (for E5 and E 10) to this GTR, shall be used, as decided by the Since three type of fuels are involved, it is necessary to provide the option for CPs to choose the one applicable to their region/ Contracting Party nation. It has been established by documents submitted by EC (EPPR-10-19) that all the Add the following new clause: three classes of evaporative emission (A, B The Contracting Parties shall accept test reports for and C) are adversely affected by volume of the approval of a vehicle according to the test fuel Ethanol added to the blend. used given in Table – B.3.# Test fuel mandated by the Contracting Party Compliance to type IV test using E10 E10 E5 E5/E10 E0 E10/E5/E0 Hence, it necessary to prescribe the hierarchy of the different blends.

The proposed limits are acceptable to India. So far there have not been any comments on these limit values. Table B.3.-2 para 5.1 Permeability test (mg/m2/24h) to be corrected to Permeability test (mg/m2/24h) Unit correction appropriately. India feels that UN 1 should be specified to start with. And when the GTR is stabilized, the UN 2 can be added later. 17 B.3 Table B.3.-3 This table may be shifted to Section A with addition of permeability limits as a future plan for CPs to adopt after this GTR has been adopted. 18 B.3 6.
