COMMISSION OF THE EUROPEAN COMMUNITIES ft^ft ft ft ft ft ft ft ft^ft Brussels, 03. 09. 1998 COM(1998) 472 final 98/0247 (COD) Proposal for a EUROPEAN PARLIAMENT AND COUNCIL DIRECTIVE on action to be taken against the emission of gaseous and particulate pollutants by engines intended to power agricultural or forestry tractors and amending Council Directive 74/150/EEC (presented by the Commission) EXPLANATORY MEMORANDUM Road traffic has long been recognized as being a major source of air pollution by substances such as carbon monoxide (CO), unburned hydrocarbons (HC), nitrogen oxides (Nox) and particulates (PT). Recent Commission studies show fairly clearly that emissions from mobile machinery, essentially operating off the road, and agricultural or forestry tractors, are also significant. The first European measures in this area were intended to reduce road-vehicle emissions in successive stages. More recently Parliament and the Council adopted Directive 97/68/EC, which applies to off-road mobile machinery, in order also to reduce the emissions by this in stages. The sixth recital of that Directive states that emissions control legislation on agricultural and forestry tractors with requirements analogous to those laid down for off-road mobile machinery so as to ensure an equivalent level of environmental protection should also be introduced as soon as possible. This proposal covers those requirements. They concern, in particular, the definition of the component type-approval procedures applying to engines intended to be fitted to tractors and thus also the definition of the type-approval procedures for such vehicles in terms of their pollutant emissions. At the request of the Member States and interested circles it was agreed, in order to achieve economic consistency and industrial logic, to adopt for the component type-approval of engines and the type-approval of tractors the same test requirements as have been adopted for off-road mobile machinery, together with the corresponding limit values for the emission levels. In addition, the equivalence between the technical requirements set out in this proposal concerning stage 1 and those of UN/ECE Regulation No 96 is recognized with that same industrial logic in mind in order to make it easier to enter third-country markets. Finally, in order to add flexibility to the engine market it is planned, for the first stage, also to recognize the technical requirements set out in Council Directive 88/77/IWC concerning emissions by diesel engines for use in vehicles. The European type-approval of tractors that has gradually been built up since 1974 is based on framework Directive 74/150/EEC, as last amended by Directive 97/54/EC, and on 22 separate directives. The aim is to create a single approval system that guarantees free movement within the Union. For the moment implementation of the Directives and full-vehicle approval remain optional. Each manufacturer may thus decide freely whether to use them or not. However, Where a choice is made to certify either an engine that is intended to power tractors or else a tractor in accordance with those Directives, the Member States are required to authorize the free movement of these. Those 22 separate Directives include Council Directive 77/537/EEC relating to the measures to be taken against the emission of pollutants from diesel engines for use in tractors, but which only deals with the opacity of the exhaust gases. This proposal supplements that Directive 77/537/EEC by drawing a distinction between the four pollutant chemical components (CO, Nox , HC and PT). It is therefore necessary to amend framework Directive 74/15 0/EEC in order to add a further heading to Annex II which mentions the subject covered by this proposal, together with the code SD (separate Directive. ). Proposal for a EUROPEAN PARLIAMENT AND COUNCIL DIRECTIVE on action to be taken against the emission of gaseous and particulate pollutants by engines intended to power agricultural or forestry tractors and amending Council Directive 74/150/EEC THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof, Having regard to the proposal from the Commission1, Having regard to the opinion of the Economic and Social Committee2, Acting in accordance with the procedure laid down in Article 189b of the Treaty3, 1. 2. to ensure the proper functioning of Whereas, internal market.

Article 2 The procedure for granting component type-approval for an engine type or family in respect of pollutant emissions, the procedure for granting type-approval for tractors in respect of pollutant emissions, and the conditions for the unrestricted placing on the market of such engines and tractors, shall be as laid down in Directive 74/150/EEC. Article 3 1. 2. Any engine type or family shall meet the requirements of Annex I in respect of pollutant emissions. Any tractor type shall meet the requirements of Annex II in respect of pollutant emissions. 1. As from 1 January 2001, Member States may not: Article 4 refuse to grant EC component type-approval or national component type-approval in respect of an engine type or family, or prohibit the sale of such engines, if the pollutants emitted by those engines meet the requirements of this Directive, or refuse to grant EC type-approval or national type-approval of tractors, or prohibit the initial entry into service of tractors, if the pollutants emitted by the engine fitted to those tractors meet the requirements of this Directive. 2. As from 1 October 2001, Member States: may no longer grant EC type-approval for a tractor type, shall refuse to grant national type-approval for a tractor type, where the pollutants emitted by the engine fitted to that tractor type do not meet the requirements of this Directive. 3. As from 1 October 2003, Member States shall prohibit the initial entry into service of tractors where the pollutants emitted by their engines do not meet the requirements of this Directive. Article 5 The authorities of Member States granting EC component type-approval for a type or family of engines or EC type-approval for a type of tractor shall recognize the component type-approvals or type-approvals granted in accordance with the provisions of section 3 of Annex I and section 3 of Annex II and the corresponding component type-approval or type-approval marks. Article 6 On the basis of a proposal which the Commission shall, if need be, put forward by the end of 2004, the European Parliament and the Council shall decide on a further reduction in emission limit values by the end of 2006. In its proposal, drawn up on the basis of research and cost/efficiency assessments of the application of more stringent limit values, the Commission will propose measures that are proportional and reasonable with regard to the targets set, taking account of the overall availability of techniques for controlling air-polluting emissions from engines and the incorporation of new engine systems and accessories into tractors, and of the air-quality situation. Article 7 1. 2. Member States may provide tax incentives for tractors and engines that are intended to power such tractors only where they comply with the anti-pollution measures laid down in this Directive. The incentives referred to in paragraph 1 shall comply with the provisions of the Treaty and fulfil the following conditions: they shall be valid for all new tractors and engines sold on the market of a Member State which meet the requirements of this Directive in advance; they shall end with the mandatory application of the limit values laid down in this Directive; they shall, for each type of tractor and engine, be lower than the extra cost of the technical solutions introduced and of fitting the engine to the tractor in such a way that the values laid down are not exceeded. 3. The Commission shall be informed of any plans to introduce or change any of the tax incentives referred to in the first paragraph sufficiently early for it to comment thereon. Article 8 Any amendments needed in order to adapt the requirements of the Annexes to technical progress shall be adopted in accordance with the procedure laid down in Article 13 of Directive 74/150/EEC.

In some cases there may be interaction of parameters. These effects must also be taken into consideration in order to ensure that only engines with similar exhaust emission characteristics are included within an engine family. For engines to be considered to belong to the same engine family, the following list of basic parameters must be common: Combustion cycle: 2 stroke/4 stroke1 Cooling medium: air/water/oil1 Swept volume: - swept volumes to be within a total spread of 15% - the number of cylinders for engines with after-treatment device must be identical Method of air aspiration: naturally aspirated/pressure charged1 Combustion chamber type/design - pre-chamber - swirl chamber - open chamber Valve and porting - configuration, size and number - cylinder head - cylinder wall -crankcase Fuel system - pump-linc-injector - in-line pump - distributor pump - single element - unit injector 14 3. 1. 8 3. 1. 9 3. 1. 10 3. 1. 11 3. 1. 12 3. 1. 13 3. 1. 14 3. 1. 15 3. 2. 3. 2. 1 3. 2. 2 3. 3 3. 3. 1 3. 3. 2 Exhaust gas recirculation Water injection/emulsion1 Air injection Charge cooling system Oxidation catalyst Reduction catalyst Thermal reactor Particulates trap Choice of the parent engine The parent engine of the family shall be selected using the primary criterion of the highest fuel delivery per stroke at the declared maximum torque speed. If two or more engines share this primary criterion, the parent engine shall be selected using the secondary criterion of highest fuel delivery per stroke at rated speed. Under certain circumstances, the approval authority may conclude that the worst-case emission rate of the family can best be characterized by testing a second engine. Thus, the approval authority may select an additional engine for tests based upon features which indicate that it may have the highest emission levels of the engines within that family. If engines within the family incorporate other variable features which could be considered to affect exhaust emissions, these features must also be identified and taken into account in the selection of the parent engine.

Any engine approved as a separate technical unit must bear: 1. 1 the trademark or trade name of the engine's manufacturer; 1. 2 the engine type, and if applicable engine family, and a unique engine identification number; 1. 3 the EC component type-approval number in accordance with Annex II. 2. 3. These marks must last throughout the useful life of the engine and remain clearly legible and indelible. If labels or plates are used, they must be affixed in such a way that they too last throughout the useful life of the engine, and the labels/plates cannot be removed without destroying or defacing them. These marks must be secured to an engine part that is necessary for normal engine operation and not normally requiring replacement during engine life. These marks must be located so as to be readily visible to the average person once the engine has been fitted to the tractor, together with all the accessories needed for engine operation. If a bonnet is to be removed in order to make the mark visible, this requirement shall be considered to have been met if removal of that bonnet is simple and does not require the use of a tool. In case of doubt concerning the meeting of this requirement, it shall be considered to have been met if an additional mark containing at least the engine identification number and the name, trade name or logo of the manufacturer has been added. That additional mark shall be affixed to, or next to, a major component that would not normally have to be replaced during the service life of the engine, and be easily accessible, without the assistance of tools, during routine maintenance operations; otherwise, it must be located at a distance from the original mark on the engine crankcase. The original mark and, where appropriate, the additional mark shall both be clearly visible once all of the accessories needed for the operation of the engine have been fitted. A bonnet meeting the requirements set out in the above paragraph shall be authorized. The additional mark shall be affixed in a durable manner directly to the topside of the engine, for example by means of an engraving, or a sticker or plate that meets the requirements of item 2. 4. The engines must be classified by means of their identification numbers in such a way that the production sequence can be determined unambiguously. 21 5. 6. Before leaving the production line, the engines must bear all of the required marks. The exact location of the engine marks shall be declared in the information document, in accordance with Annexes I and II. 22 ANNEX I APPENDIX 4 NUMBERING The identification of the EC component type-approval shall consist of: a rectangle containing: a lower-case letter "e" followed by the distinguishing number or Ietter(s) of the Member State which has granted the component type- approval: "1" for Germany "2" for France "3" for Italy "4" for the Netherlands "5" for Sweden "6" for Belgium "9" for Spain "11" for the United Kingdom "12" for Austria "13" for Luxembourg "17" for Finland "18" for Denmark "21" for Portugal "23" for Greece "IRL" for Ireland below this, an EC component type-approval number located close to the right-hand corner and corresponding to the number of the EC component type-approval certificate for the engine type or family in question. 23 Example of an EC component type-approval mark a > 30 mm 66 - 2405 Legend: The engine bearing the above component type-approval mark was component type approved in Germany (el) under number 66-2405. 24 ANNEX II REQUIREMENTS FOR THE EC TYPE-APPROVAL OF A TRACTOR EQUIPPED WITH A COMPRESSION IGNITION ENGINE IN RESPECT OF THE POLLUTANTS EMITTED 1. 1. 1 1. 2 2. 2. 1 2. 2 DEFINITIONS Type of tractor in terms of the pollutants emitted.
