Experts from the following countries and non-governmental organizations participated in the work: Belgium; Czech Republic; Denmark; France; Germany; Hungary; Italy; Japan; Netherlands; Norway; Poland; Sweden; United Kingdom; United States of America; International Organization of Motor Vehicle Manufacturers (OICA). The report on the proceedings of this informal meeting by the Chairman of the ad hoc group is reflected in paragraphs 710 of this report. 3.bbThe documents without a symbol distributed during the session are listed in annex 1 to this report. REGULATION No. 83 03 series of amendments (Emissions of M1 and N1 categories of vehicles) Documentation: Informal document No. 14 of annex 1 to this report. 4.bbThe Meeting of Experts noted the information by the expert from France that informal document No. 14 had been prepared with a view to aligning Regulation No. 83 with the provisions of EU Directive 94/12/EC (amending Directive 70/220/EEC). To allow for timely processing, and noting its previous adoption of the substantial part of the proposal during the twentyseventh session (TRANS/WP.29/GRPE/27, paras. 5 and 6, document TRANS/SC.1/WP.29/GRPE/R.225), the Meeting of Experts examined and adopted the proposed amendments. The secretariat was requested to prepare an appropriate official document, and transmit it to the Working Party on the Construction of Vehicles for its onehundredandsixth session, to be considered as draft 03 series of amendments to Regulation No. 83. REGULATION No. 49 (Emissions of compressionignition engines) (a)bb02 series of amendments Documentation: TRANS/SC.1/WP.29/GRPE/R.218, informal document No. 7 of annex1 to this report. 5.bbThe expert from Belgium informed the Meeting of Experts that draft corrigenda to the 02 series of amendments to the Regulation contained in informal document No. 7 had been prepared on the basis of document TRANS/SC.1/WP.29/GRPE/R.218, with a view to maintaining alignment with EUDirective 88/77/EEC, as amended by Directive 91/542/EEC. He also indicated that the items concerned were mostly of an editorial nature and agreed with the expert from Poland that some of them had already been resolved when the final text of the Regulation had been issued. 6.bbThe Meeting of Experts considered and adopted informal document No. 7 with a number of amendments. The secretariat was requested to transmit the adopted text (reproduced in annex 2 to this report) as a draft Corrigendum 2 to the 02series of amendments to Regulation No. 49 to the Working Party(|,})}) onthe Construction of Vehicles for consideration at its onehundredandsixth session. (b)7bbDevelopment of the emission testing procedure#b Documentation: Informal documents Nos. 9 and 10 of annex 1 to this report. 7.bbThe Chairman of the ad hoc group on the development of an emission testing procedure for heavy duty engines summarized to the Meeting of Experts the proceedings of the informal meeting held on 16 January 1995 (para.2above). 8.bbHe reported that an initial AVL study (TRANS/WP.29/GRPE/28, paras. 8 and10) had been completed on one engine (V6, turbocharged, intercooled, with electronic fuel injection), performing four steady state cycles and three transient cycles (see TRANS/WP.29/GRPE/28, para. 6, not executing the Japanese steady state test cycle) and the results had been evaluated. Another two engines, 6in-line, turbocharged and intercooled, one with mechanical injection pump, the other with electronic unit injectors, were tested in the United Kingdom. All the engines were meeting stringent emission limits (Euro II = Regulation No. 49, 02series of amendments, approval B, i.e. Directive 91/542/EEC, 1995/96 limits). Presentations of the test results and data reduction analyses were given during the ad hoc group meeting. More test data was felt to be needed to compare the candidate test cycles. Cooperation should continue also with Sweden, as had been formerly agreed. Different levels of joint financing covered the accomplished part of the work. The financing of further tests remained to be arranged. The ad hoc group reiterated that the selected cycle should best represent the real driving conditions in terms of ranking the engine emissions. The expert from the United States of America also expressed the wish to take part in the development test work, and suggested that a degree of harmonization would be desirable of the future test cycle with the Federal Test Procedure for heavy duty engines. 9.bbIn view of the discussion during the ad hoc group meeting, an exchange of views was held by the Meeting of Experts on the data available, its analysis, and specific properties of steady state and transient cycles with respect to engine design and operation. The comparability of data from different laboratories was also a subject of discussion. The expert from Japan presented informal documents Nos. 9 and10, comparing analytically the candidate test cycles, and giving information on the test cycle applied in his country (steady state), after the procedure had been revised in March 1991. He drew the attention of the Meeting of Experts to the experience showing that the steady state mode can reflect most transient conditions and provide a better accuracy and reproducibility, whilst testing equipment was less sophisticated and cheaper than for transient testing. The expert from the Czech Republic also voiced his opinion, that costeffective would be a well defined steady state cycle, which could represent the variable driving conditions whilst being effective to control emissions influenced by engine design (combustion process), with an added dynamic part, which should be selected to sample the engine management in transition operations. '|,})})Ԍ10.bbConcluding the deliberations, the Meeting of Experts restated its mandate to the ad hoc group and its Chairman and agreed that a further meeting would be held in London on 8 February 1995 to prepare a coordinated work plan, which would allow to select the most suitable future test cycle from the range considered, whilst utilizing all available resources and facilities. It was made clear that the time available was limited, and to assess the emission limits for the year2000 the data for selection of the test cycle should be evaluated for resumed consideration at the next session of the Meeting of Experts. (c)bbInclusion of gasfuelled vehicles Documentation: TRANS/WP.29/GRPE/R.242, informal documents Nos. 1 and 3 of annex 1 to this report. 11.bbThe expert from Italy informed the Meeting of Experts that document TRANS/WP.29/GRPE/R.242 was prepared following the consideration of the proposal for a new draft Regulation during the twentyeighth session (TRANS/WP.29/GRPE/28, paras. 1216) and followed the advice for incorporating the provisions for natural gas (NG) fuelled engines in Regulation No. 49, not modifying the emission limits applied in the 02 series of amendments. He indicated that to facilitate the consideration of the matter, the proposal had been distributed to the experts by mail, prior to the current session (see also annex 1 to this report). 12.bbThe expert from ISO indicated that ISO/TC193 had under consideration a study of energy content in natural gas from different sources and would, after its completion, be in the position to contribute to the specification(s) of the reference fuel. 13.bbAcknowledging the work done by the expert from Italy, the Meeting of Experts considered and adopted document TRANS/WP.29/GRPE/R.242. It was agreed that while compressed natural gas fuelled engines with closeloop catalytic converters were capable of complying with reduced emission limits, it was more important to establish the possibility of type approval of such engines, and the reduction of limits should be reserved for a later development, after an initial experience was gained. The Meeting of Experts also agreed that the adopted document should be transmitted to the Working Party on the Construction of Vehicles for consideration at its onehundredandsixth session. The expert from Italy agreed to examine his proposal once again and to communicate to the secretariat any corrigenda or additional amendments needed. He also informed the Meeting of Experts that, if adopted by the Working Party, the representative of his country in the session might consider to propose to his Government transmission of the document to the SecretaryGeneral of the United Nations. 14.bbInformal document No. 1 was introduced by the expert from the Netherlands, who explained that its aim was to introduce into Regulation No.49 provisions for liquefied petroleum gas (LPG) fuelled engines, applying the same principles as the proposal by Italy (see paras. 11 and 13 above). Though it was recognized that the combining of both proposals would be most advantageous, the Meeting of Experts agreed that more time would be needed for(|,})}) such work. The secretariat was requested to distribute informal document No.1 with an official symbol for resumed consideration at the next session. 15.bbWhile not directly related to the agenda item, informal document No. 3 was also considered by the Meeting of Experts, noting that its proposals apply to Regulations Nos. 83, 84 and 85, incorporating provisions for LPGfuelled engines. In view of this, the Meeting of Experts agreed to list the LPG-fuelled vehicles as a separate agenda item for its thirtieth session, and requested the secretariat to distribute for consideration at that session informal document No. 3 with an official symbol. REGULATION No. 67 (Equipment for liquefied petroleum gas) Documentation: TRANS/WP.29/GRPE/R.238, informal documents Nos. 2 and 8 of annex 1 to this report. 16.bbThe proposal by Poland to control the pressure gradient in the testing of LPG containers (TRANS/WP.29/GRPE/R.238) was supported by the experts from the Netherlands (informal document No. 8) and from the Czech Republic. The expert from the Netherlands agreed to incorporate a relevant provision into the proposal for amendments to the Regulation (see para. 17 below). 17.bbAn initial exchange of views was held by the Meeting of Experts on the proposal by the Netherlands to incorporate into Regulation No. 67 provisions for installation of an LPG system in vehicles (informal document No.2). The philosophy of the proposal was in general supported. The expert from Italy indicated that some additional considerations might be desirable, particularly in view of LPG equipment installations in buses. The expert from the Netherlands indicated that provisions contained in informal document No. 2 would be developed further, including also the amendment to the container test procedure (para. 16 above), and agreed to undertake the work for consideration at the next session. COLD START TESTING PROCEDURE Documentation: TRANS/WP.29/GRPE/R.237, informal document No. 5 of annex 1 to this report. 18.bbThe expert from the European Commission informed the Meeting of Experts that cold start testing was also considered in the Motor Vehicle Emission Group (MVEG) and it was agreed that the test should be composed of four elementary urban cycles at 7$C. Though no limits had been agreed, both CO and HC emissions had been discussed, based on available study results by Sweden and Finland (TRANS/WP.29/GRPE/R.237). Also the conformity of production (COP) procedure remained to be agreed, recognizing the need for a practicable method. The expert from OICA proposed that a realistic and viable COP method should be based on extrapolation of lowtemperature emission values to 20$C (informal document No. 5). 19.bbThe Meeting of Experts agreed to resume the consideration of the cold start testing procedure at the next session and a belief was expressed that at(|,})}) that time information would be complete and sufficient to make the decision by the Meeting of Experts possible. DRAFT REGULATION ON REPLACEMENT CATALYTIC CONVERTERS Documentation: Informal document No. 6 of annex 1 to this report. 20.bbThe expert from CLEPA introduced the document, noting that it combined the proposals by OICA and CLEPA and should provide a base for the future draft Regulation. The expert from OICA agreed that on the basis of this proposal the durability requirements on replacement catalytic converters could be discussed between the two organizations. 21.bbThe expert from Germany reported that, following the invitation by the Meeting of Experts during the twentyeighth session, a joint proposal by France and Germany had been prepared, but not distributed in order not to compete with the abovementioned proposal by CLEPA, intended as a base for work. He indicated the preparedness for cooperation. Referring to the experience which had been gained in his country, cooperation was also offered by the expert from the Russian Federation. 22.bbThe expert from the United Kingdom drew the attention of the Meeting of Experts to problems which might arise from different catalytic converter properties for e.g. onboard diagnostic systems set for the original converter characteristics. 23.bbThe expert from CLEPA acknowledged the above contributions and agreed to organize an informal meeting in Paris to elaborate a proposal for consideration by the Meeting of Experts at its next session. (Note by the secretariat: This meeting was later confirmed for 11 April 1995, to be held at OICA premises.) The invitation was extended to all parties concerned to contribute to this development work. APPLICATION OF ECE REGULATIONS TO ELECTRIC VEHICLES (a)bbRegulation No. 68 (Measurement of the maximum speed) Documentation: TRANS/WP.29/GRPE/R.240. 24.bbThe document was considered and adopted by the Meeting of Experts with the amendments noted below. (Note: Also included is an additional amendment communicated to the secretariat after the session by the expert from France.) Insert a new paragraph 5.2.1., to read: "5.2.1.n Thermal engine driven vehicles:" #  (|,})})ԌParagraph 5.2.2.

The expert from France informed the Meeting of Experts that, if adopted by the Working Party, the representative of her country in the session might consider to propose to his Government transmission of the document to the SecretaryGeneral of the United Nations. (b)bbRegulation No. 84 (Measurement of fuel consumption) Documentation: Informal document No. 13 of annex 1 to this report. 26.bbThe expert from France stated that the informal document had been prepared to replace the former official document (TRANS/WP.29/GRPE/R.231) and was directed to amend the draft Regulation on CO2 emissions and fuel consumption of passenger cars (TRANS/WP.29/427) instead of Regulation No. 84. This philosophy was accepted by the Meeting of Experts, and in view of providing more time to study the proposal, it was agreed to defer its detailed consideration to the next session, for which the secretariat was requested to distribute the document with an official symbol. (Note: This will include amendments communicated to the secretariat after the session by the expert from France.) 27.bbThe expert from the United States of America reported that a number of programmes were under way by the Environmental Protection Agency in his country with respect to electric vehicle rules, and that also ISO and SAE (Society of Automotive Engineers) were active in the field. He requested that compatibility should be considered for the requirements applied to electric vehicles and that cooperation was desirable. The expert from Japan confirmed that also in his country the electric vehicle association had studied the introduction of an applicable legislation. The prospects for cooperation were positively evaluated by the Meeting of Experts, considering that legislation had not yet been established in any of the regions concerned. 0(|,})})I !0Ԍ(c)bbRegulation No. 85 (Measurement of the net power) Documentation: TRANS/WP.29/GRPE/R.241. 28.bbThe document was considered and adopted by the Meeting of Experts without amendments. (However, a minor amendment was communicated to the secretariat after the session by the expert from France and is noted below:) Annex 2, item 6, amend to read: 7bb"6. International protection (IP) code: #bp"#Y" 29.bbThe Meeting of Experts agreed to transmit the adopted document to the Working Party on the Construction of Vehicles for consideration at its onehundredandsixth session. The expert from France indicated that, if adopted by the Working Party, the representative of her country in the session might consider to propose to his Government transmission of the document to the SecretaryGeneral of the United Nations. (d)bbSpecific requirements for electric vehicles Documentation: TRANS/WP.29/GRPE/R.233. 30.bbThe expert from France reported that development work on this proposal was still under way with ISO and CEN cooperating (TRANS/WP.29/GRPE/28, para.40). Some views were exchanged by the Meeting of Experts on the provisions of the proposal, including principles of protection against electric shock. It was agreed to resume the consideration of this agenda item at the next session, expecting that progress might be made by that time. 31.bbConcluding the discussion, the Meeting of Experts commended the work by the expert from France and her small informal group, not only on the proposal for safety of electric vehicles, but also on other proposals for incorporating the electric vehicle provisions into various ECE Regulations. 32.bbBased on the request by Italy, the Meeting of Experts agreed in principle that all amendments to ECE Regulations regarding electric vehicles might in the future be extended to hybrid vehicles, if such technology appeared to be commercially available and suitable proposals were prepared for consideration.

Environmental class I vehicle tax incentive will be equalled to that of class II, but such vehicles will be exempted for 6 months from the road tax. Electric vehicles also exempted from the road tax. United Kingdom: EU followed; motorcycle silencers requested to be properly marked (mainly noise concerns); in the control of vehicles in service problems experienced with accuracy of  measurement. United States of America:;;1 Revised lightduty vehicles duty cycle changes anticipated in mid 1995 (influence of the use of airconditioners, heavy accelerations and extended soak periods followed by engine restart); For phase II rule development for nonroad engines over 37 kW three vehicles were instrumented (tractor, backhoe, bulldozer) speed, torque and time being analyzed in order to develop a duty cycle; Recreational marine engines final rule expected later this year. Locomotives first rule expected in 1995; Motorcycles the rules should be revisited later this year; Offroad recreational vehicles, regulatory rule considered. OTHER BUSINESS (a)Alternative fuels for internal combustion engines 34.Taking into account that natural gas and liquefied petroleum gas fuelled vehicles were being already addressed, the Meeting of Experts decided to withdraw this item from the agenda until further proposals would be received. (b)Inspection of vehicles in use 35.Information was noted, as given by the experts in the exchange of news on national and international requirements on emissions (see para. 42 above). The Meeting of Experts agreed to resume consideration of this matter after suitable working proposal(s) would be available. (c)Draft Regulation on the emissions of agricultural and forestry tractors Documentation: TRANS/WP.29/395, TRANS/WP.29/GRPE/R.235, informal document No. 4 of annex 1 to this report. 36.The publication of the final text of the draft Regulation was noted (TRANS/WP.29/395), as well as its transmission by the secretariat on( |,})}) 10January 1995 to the countries who agreed to consider communication of the text to the SecretaryGeneral of the United Nations (United Kingdom, Italy). 37.Document TRANS/WP.29/GRPE/R.235 was considered but, however, only the amendment to paragraph 1 of the draft Regulation was adopted by the Meeting of Experts. It was agreed to consider the adopted text as a draft Corrigendum 1 to the Draft Regulation, and the secretariat was requested to prepare arelevant document for consideration by the Working Party at its onehundredandsixth session. 38.Informal document No. 4 advising the Meeting of Experts of differences between the draft Regulation and the proposal for EU Directive on nonroad mobile machinery was briefly examined, and the Meeting of Experts agreed to evaluate it in detail at its next session, for which the secretariat was requested to distribute the text with an official symbol. The expert from the European Commission indicated that results of a background study had become available, and showed that not negligible emissions were produced by nonroad machinery compared to road vehicles (40 per cent of NOx compared to that produced on road and 30 per cent of particulates produced compared to road). 39.The expert from the United States of America supported the intentions to consider further harmonization of the draft Regulation and the proposed EU Directive. He indicated that also in his country the rule for nonroad machinery might be updated in order to achieve a higher degree of harmonization. He also said that reference fuel specifications should not be excluded from the consideration in order to allow common fuel to be used. He agreed to prepare for the next session an information document on tractor fuels used in his country, in order to facilitate such discussions. He also suggested to consider further the possibilities of extension of the draft Regulation to nonroad machinery in order to curb emissions produced by such equipment. (d)XInformation on the work of the Executive Body for theConventiononLongRange Transboundary Air Pollution# Documentation: EB.AIR/WG.6/R.16/Rev.1. 40.A document containing a summary of options for further reduction of nitrogen oxide emissions from onroad heavyduty vehicles, and prepared by governmentally designated experts was distributed for information. It was noted that it had been compiled to provide a base for draft amendments to partII of the technical annex to the Protocol concerning the Control of Emissions of Nitrogen Oxides. (e)Environmental standards for vehicles in international traffic Documentation: TRANS/R.396. 41.The Meeting of Experts noted the consideration of the ECMT proposal for establishing environmental standards for vehicles in international traffic in e.g. the Vienna Convention during the onehundredandfourth session by the( |,})}) Working Party (TRANS/WP.29/427, paras. 86 and 87), as well as the mandate given for consideration of this matter by the Inland Transport Committee at its fiftyseventh session (ECE/TRANS/111, paras.58 and 59). It was also noted that the proposal had become closely related to the 1996 Regional Conference on Transport and the Environment, and was under consideration for its final outcome. Giving a complementary information, the expert from the European Commission stated that in the Environmental Council a Resolution on Transport and the Environment had been prepared and, as a formal document of the EU Council of Ministers, should be transmitted to the Preparatory Committee of the 1996 Regional Conference. 42.During the consideration of the proposal, a question was raised by the expert from the Czech Republic, regarding the provisions necessary for checking that vehicles approved to Regulation No.49 retained their environmental performance in service. Proposals were made to certify such compliance by inspection and maintenance certificates, or to allow the checks of visible pollutants according to Regulation No. 24. The Meeting of Experts agreed in principle that with respect to the high utilization rate of vehicles in long distance international transport, relevant provisions needed to be proposed to complete the ECMT proposal. Opinions were also voiced that the introduction of environmental standards should be justified before any decision was made, and impacts of such a measure assessed both on the environment and on the international transport and related economy. The expert from Poland indicated that in this respect the entry into force of such environmental standards was also of importance and indicated his intention to prepare for the next session a working paper with the analysis of technical and economical impacts. 43.Noting the urgency of the matter, and in the absence of immediate answers by the parties which had been involved in the preparation of the proposal, the Chairman invited the experts to consider the preparing of proposals for resolving the abovementioned questions and to contribute to the consideration of the matter also by data needed to evaluate its possible impacts. Tofacilitate a fruitful discussion, a deadline for such contributions was set for 31 March 1995, and the secretariat was requested to compile an official working document for consideration at the thirtieth session of the Meeting of Experts, and/or arrange otherwise for the receiving of the individual contributions prior to the session by the participants. It was stressed that the contribution of the Meeting of Experts should focus on preparing technically and juridically correct provisions, thus making the proposal viable. (f)Regulation No. 40 (Emissions of motorcycles) 44.The information by the secretariat was noted, that its attention had been drawn by an external user to inconsistency in the provisions of the Regulation, i.e. to mentioning of "unburnt hydrocarbons" in TypeII test procedure (Annex 5, paragraph 2.2. of the Regulation), whilst only CO content was limited (TypeII test, paragraph 5.2.1.2.1.). It was also suggested that the text of the Regulation should be considered significant and the reference to unburnt hydrocarbons deleted. The expert from IMMA agreed to examine the matter and provide information for resolving it at the next session.( |,})})Ԍ(g)XInternational legal instruments on the protection of the environment inthe field of transport# Documentation: ECE/RCTE/PC/9/Add.1. 45.The secretariat introduced the document, explaining that it had been compiled for the third session (1213 January 1995) of the Preparatory Committee of the 1996 Regional Conference on transport and the environment, and requested the Meeting of Experts to examine it with respect to pollutant emission and energy consumption data, and transmit to the secretariat any comments or corrigenda, if necessary. It was also indicated that a similar procedure would later be taken for examination of the section referring to ECEnoise Regulations. (h)Exhaust emission standards for small RIC engines of less than 37 kW Documentation: Informal document No. 15 of annex 1 to this report. 46.The publication by Euromot was distributed for information. AGENDA FOR THE NEXT SESSION 47.To facilitate the presentation of the results of the work of the ad hoc group to the Meeting of Experts (see para. 10 above), it was conceded that the ad hoc group on the development of an emission testing procedure for heavy duty engines should meet prior to the thirtieth session; the following timetable and agenda were agreed: Monday, 10 July 1995, 9.30 h 12.30 h: Meeting of the ad hoc group (informal meeting without simultaneous interpretation); Monday, 10 July, 14.30 h Thursday 13 July 1995, 17.30 h: Thirtieth session proper, with the following provisional agenda: 1.1/ Regulation No. 49 (Emissions of compressionignition engines)#  Development of the emission testing procedure 2.2/ Environmental standards for vehicles in international traffic 3.3/ Application of ECE Regulations to electric vehicles  3.1.4_ _ "Draft Regulation on CO2 emissions and fuel consumption of passenger cars#_  3.2.4_ _ "Specific requirements for electric vehicles#_ __________  1/This item will be considered on Monday, 10 July 1995, afternoon. 2/This item will be considered on Tuesday, 11 July 1995, morning. 3/XThis item will be considered on Tuesday, 11 July 1995, afternoon.#( |,})})Ԍ4.
