ENGINE FAMILY 8.1. Parameters defining the engine family The engine family may be defined by basic design parameters which must be common to all engines within the family. 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. 8.1.1. Combustion cycle: 2 stroke/4 stroke(1) 8.1.2. Cooling medium: air/water/oil(2) 8.1.3. Individual cylinder displacement - engines to be within a total spread of 15 % - number of cylinders for engines with after-treatment device 8.1.4. Method of air aspiration: naturally aspirated/pressure charged(3) 8.1.5. Combustion chamber type/design - pre-chamber - swirl chamber - open chamber 8.1.6. Valve and porting - configuration, size and number - cylinder head - cylinder wall - crankcase 8.1.7. Fuel system - pump-line-injector - in-line pump - distributor pump - single element - unit injector 8.1.8. Exhaust gas recirculation 8.1.9. Water injection/emulsion(4) 8.1.10. Air injection 8.1.11. Charge cooling system 8.1.12. Oxidation catalyst 8.1.13. Reduction catalyst 8.1.14. Thermal reactor 8.1.15. Particulates trap 8.2. Choice of parent engine 8.2.1. 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 characterised by testing a second engine. Thus, the approval authority may select an additional engine for tests based on features which indicate that it may have the highest emission levels of the engines within that family. 8.2.2. 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.

STATEMENT OF THE COUNCIL'S REASONS I. INTRODUCTION 1. On 7 September 1998, the Commission submitted a proposal, based on Article 95 (formerly Article 100a) of the EC Treaty, amending Directive 74/150/EEC on the approximation of the laws of the Member States relating to measures to be taken against the emission of gaseous and particulate pollutants by engines intended to power agricultural or forestry tractors. 2. The European Parliament delivered its opinion on 5 May 1999 and proposed four amendments to the Commission proposal. In the light of that opinion the Commission submitted an amended proposal on 18 August 1999, incorporating two of the European Parliament's amendments. 3. The Economic and Social Committee delivered its opinion on 29 January 1999. 4. On 22 November 1999, the Council adopted a common position on the Commission proposal in accordance with Article 251 of the Treaty. II. OBJECTIVE 5. The objective of the Commission's proposal is to introduce emissions-control legislation on agricultural and forestry tractors analogous to that laid down for off-road mobile machinery in Directive 97/68/EC so as to ensure an equivalent level of environmental protection. The proposal covers those requirements which, in particular, concern the component type-approval procedures applying to engines intended to be fitted to tractors and thus also to the definition of the type-approval procedures for such vehicles in terms of their pollutant emissions. Furthermore, the Directive applies the same test requirements as the ones that have been adopted for off-road mobile machinery and the emission limit values are also the same. III. ANALYSIS OF THE COMMON POSITION 6. Preliminary comment In establishing a common position, the Council has slightly modified the original Commission proposal seeking to make it clearer and changing certain deadlines, in particular as far as application dates are concerned (Article 4). 7. Enacting terms (a) Recitals Recital 5 of the original Commission proposal has been deleted as a result of the deletion of Article 7 on tax incentives. (b) Article 4 Article 4 has been completely redrafted as the Council considered that the original proposal on the timetable was not clear enough. Thus, precise dates for all categories of engines have been introduced in order to render the Directive more readable and to allow for more flexibility for manufacturers. (c) Previous Article 7 The Council has decided to delete the original Article 7 on tax incentives as it seems unjustified to legislate on this in the field of agricultural tractors. Furthermore, the Council has found it best to follow Directive 97/68/EC which does not contain any provision on tax incentives. (d) Articles 3, 5 and 6 The drafting of Articles 3, 5 and 6 differs slightly from the original Commission proposal as the Council found that the previous text lacked clarity. (e) Annex III In order to group the equivalencies with other EC regulations referred to in the Commission proposal, the Council has found it useful to add new Annex III on the recognition of alternative type-approvals.
