DIRECTIVE 97/68/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 16 December 1997

on the approximation of the laws of the Member States relating to measures against the emission of gaseous and particulate pollutants from internal combustion engines to be installed in non-road mobile machinery







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 Commission ( 1 ), Having regard to the opinion of the Economic and Social Committee ( 2 ), Acting in accordance with the procedure laid down in Article 189b of the Treaty ( 3 ), in the light of the joint text approved by the Conciliation Committee on 11 November 1997, (1) Whereas the Community programme of policy and action in relation to the environment and sustainable development ( 4 ) recognizes as a fundamental principle that all persons should be effectively protected against recognized health risks from air pollution and that this necessitates in particular the control of emissions of nitrogen dioxide (NO2), particulates (PT) — black smoke, and other pollutants such as carbon monoxide (CO); whereas with regard to the prevention of tropospheric ozone (O3) formation and its associated health and environmental impact, the emissions of the precursors nitrogenoxides (NOx) and hydrocarbons (HC) must be reduced; whereas the environmental damage caused by acidification will also require reductions inter alia on the emission of NOx and HC; (2) Whereas the Community signed the UN/ECE protocol on volatile organic compound (VOC) reduction in April 1992 and adhered to the protocol on NOx reduction in December 1993, both of which are related to the 1979 Convention on Long-range Transboundary Air Pollution which was approved in July 1982; (3) Whereas the objective of reducing the level of pollutant emissions from non-road mobile machinery engines and the establishment and operation of the internal market for engines and machinery cannot be sufficiently achieved by individual Member States, and can therefore be better achieved by the approximation of the laws of the Member States relating to measures against air pollution by engines to be installed in non-road mobile machinery; (4) Whereas recent investigations undertaken by the Commission show that the emissions from non-road mobile machinery engines constitute a significant proportion of the total man-made emissions of certain noxious atmospheric pollutants; whereas the category of compression ignition engines which will be regulated by this Directive is responsible for a considerable share of air pollution by NOx and PT, in particular when it is compared with that coming from the road transport sector; (5) Whereas emissions from non-road mobile machinery operating on the ground equipped with compression ignition engines, and in particular the emissions of NOx and PT, constitute a primary cause of concern in this area; whereas these sources should be regulated in the first instance; whereas, however, it will also be appropriate subsequently to extend the scope of this Directive to include the control of emissions from other non-road mobile machinery engines, including transportable generating sets, based on appropriate test cycles, and in particular from gasoline engines; whereas a considerable reduction of the CO and HC emissions may be achievable with the envisaged enlargement of the scope of this Directive to include gasoline engines; (6) Whereas emissions control legislation on agricultural and forestry tractor engines, ensuring a level of environmental protection equivalent to the level established pursuant to this Directive, with standards and requirements fully consistent with it, should be introduced as soon as possible; (7) Whereas, in respect of certification procedures, that type-approval approach has been taken which, as a European method, has stood the test of time for approvals of road vehicles and their components; whereas, as a new element, the approval of a parent engine on behalf of a group of engines (engine family) built using similar components according to similar construction principles, has been introduced; (8) Whereas the engines produced in compliance with the requirements of this Directive will have to be accordingly marked and notified to the approval authorities; whereas, in order to keep administrative burdens low, no direct control by the authority of the engine production dates relevant for strengthened requirements has been foreseen; whereas this freedom for the manufacturers requires them to facilitate the preparation of spot checks by the authority and to make available relevant production planning information at regular intervals; whereas absolute compliance with notification made in accordance with this procedure is not obligatory but a high degree of compliance would facilitate the approval authorities' planning of assessments and contribute to a relationship of increased trust between manufacturers and type-approval authorities; (9) Whereas approvals granted in accordance with Directive 88/77/EEC ( 5 ) and with UN/ECE Regulation 49 Series 02, as listed in Annex IV, Appendix II to Directive 92/53/EEC ( 6 ) are recognized as equivalent to those required by this Directive in its first stage; (10) Whereas engines which are in compliance with the requirements of this Directive and covered by its scope must be permitted to be placed on the market in the Member States; whereas these engines must not be subject to any other national emission requirement; whereas the Member State granting approvals will take the necessary control measures; (11) Whereas, in laying down the new test procedures and limit values, it is necessary to take into account the specific usage patterns of these types of engines; (12) Whereas it is appropriate to introduce these new standards according to the proven principle of a two-stage approach; (13) Whereas, for engines with higher power output, the achievement of substantial emission reduction seems to be easier, as existing technology that has been developed for engines of road vehicles can be used; whereas, taking this into account a staggered implementation of the requirements has been foreseen, beginning with the highest of three powerbands for stage I; whereas this principle has been retained for stage II with the exception of a new fourth powerband not covered by stage I; (14) Whereas for this sector of non-road mobile machinery applications, which is now regulated and is the most important one besides agricultural tractors if compared with emissions coming from road transport, a considerable reduction of emissions can be expected by the implementation of this Directive; whereas due to, in general, very good performance of diesel engines with respect to CO and HC emissions, the margin for improvement in respect of the total amount emitted is very small; (15) Whereas, in order to make provision for the case of exceptional technical or economic circumstances, procedures have been integrated which could exempt manufacturers from the obligations arising from this Directive; (16) Whereas, in order to ensure ‘conformity of production’ (COP) once an approval is granted for an engine, manufacturers will be required to provide corresponding arrangements; whereas provisions have been made for the case of discovered non-conformity which lay down information procedures, corrective actions and a cooperation procedure which will allow the settling of possible differences of opinion between Member States in respect of conformity of certified engines; (17) Whereas the entitlement of Member States to lay down requirements ensuring that workers are protected when using non-road mobile machinery shall not be affected by this Directive; (18) Whereas the technical provisions in certain Annexes to this Directive should be supplemented and, as necessary, adapted to technical progress according to a committee procedure; (19) Whereas provisions should be laid down to ensure testing of the engines in compliance with the rules of good laboratory practice; (20) Whereas there is a need to promote global trade in this sector by harmonizing, as far as possible, emission standards in the Community with those applied or planned in third countries; (21) Whereas it is therefore necessary to envisage the possibility of reconsidering the situation on the basis of the availability and the economic feasibility of new technologies and taking account of progress achieved in the implementation of the second stage; (22) Whereas an agreement on a modus vivendi between the European Parliament, the Council and the Commission concerning the implementing measures for acts adopted in accordance with the procedure laid down in Article 189b of the Treaty was reached on 20 December 1994 ( 7 ), HAVE ADOPTED THIS DIRECTIVE:

Article 5

Amendments to approvals

1. The Member State which has granted type-approval must take the necessary measures to ensure that it is informed of any change in the particulars appearing in the information package.

2. The application for the amendment or extension of a type-approval shall be submitted exclusively to the approval authority of the Member State which granted the original type-approval.

3. If particulars appearing in the information package have changed, the approval authority of the Member State in question shall:

— issue revised page(s) of the information package as necessary, marking each revised page to show clearly the nature of the change and the date of re-issue. Wherever revised pages are issued the index to the information package (which is attached to the type-approval certificate) shall also be amended to show the latest dates of revised pages, and

— issue a revised type-approval certificate (denoted by an extension number) if any information on it (excluding its attachments) has changed or if the standards of this Directive have changed since the date currently on the approval. The revised certificate shall show clearly the reason for revision and the date of re-issue.

If the approval authority of the Member State in question finds that an amendment to an information package warrants fresh tests or checks, it shall inform the manufacturer thereof and issue the documents mentioned above only after the conduct of successful fresh tests or checks.

Article 6

Conformity

1. The manufacturer shall affix to each unit manufactured in conformity with the approved type the markings as defined in section 3 of Annex I, including the type-approval number.

►M2 4.1.1. ◄ General

The components liable to affect the emission of gaseous and particulate pollutants shall be so designed, constructed and assembled as to enable the engine, in normal use, despite the vibrations to which it may be subjected, to comply with the provisions of this Directive.

The technical measures taken by the manufacturer must be such as to ensure that the mentioned emissions are effectively limited, pursuant to this Directive, throughout the normal life of the engine and under normal conditions of use. These provisions are deemed to be met if the provisions of sections ►M2 4.1.2.1 ◄ , ►M2 4.1.2.3 ◄ and 5.3.2.1 are respectively complied with.

If a catalytic converter and/or a particulates trap is used the manufacturer must prove by durability tests, which he himself may carry out in accordance with good engineering practice, and by corresponding records, that these after-treatment devices can be expected to function properly for the lifetime of the engine. The records must be produced in compliance with the requirements of section 5.2 and in particular with section 5.2.3. A corresponding warranty must be guaranteed to the customer. Systematic replacement of the device, after a certain running time of the engine, is permissible. Any adjustment, repair, disassembly, cleaning, or replacement of engine components or systems which is performed on a periodic basis to prevent malfunction of the engine in context with the after-treatment device, shall only be done to the extent that is technologically necessary toassure proper functioning of the emission control system. Accordingly scheduled maintenance requirements must be included in the customer's manual, and be covered by the warranty provisions mentioned above, and be approved before an approval is granted. The corresponding extract from the manual with respect to maintenance/replacements of the treatment device(s), and to the warranty conditions, must be included in the information document as set out in Annex II to this Directive.

▼M3

All engines that expel exhaust gases mixed with water shall be equipped with a connection in the engine exhaust system that is located downstream of the engine and before any point at which the exhaust contacts water (or any other cooling/scrubbing medium) for the temporary attachment of gaseous or particulate emissions sampling equipment. It is important that the location of this connection allows a well mixed representative sample of the exhaust. This connection shall be internally threaded with standard pipe threads of a size not larger than one-half inch, and shall be closed by a plug when not in use (equivalent connections are allowed).

6. PARAMETERS DEFINING THE ENGINE FAMILY

The engine family may be defined by basic design parameters which must be common to engines within the family. In some cases there may be interaction of parameters. These effects must also be taken into consideration to ensure that only engines with similar exhaust emission characteristics are included within an engine family.

In order that engines may be considered to belong to the same engine family, the following list of basic parameters must be common:

6.1. Combustion cycle: — 2 cycle — 4 cycle

6.2. Cooling medium: — air — water — oil

▼M2

6.3. Individual cylinder displacement, within 85 % and 100 % of the largest displacement within the engine family

6.4. Method of air aspiration

6.5. Fuel type — Diesel — Petrol.

6.6. Combustion chamber type/design

6.7. Valve and porting — configurations, size and number

6.8. Fuel system For diesel: — pump-line injector — in-line pump — distributor pump — single element — unit injector. For petrol: — carburettor — port fuel injection — direct injection.

6.9. Miscellaneous features — Exhaust gas recirculation — Water injection/emulsion — Air injection — Charge cooling system — Ignition type (compression, spark).

6.10. Exhaust after-treatment — Oxidation catalyst — Reduction catalyst — Three way catalyst — Thermal reactor — Particulate trap.

▼B

7. CHOICE OF THE PARENT ENGINE

7.1. The parent engine of the family shall be selected using the primary criteria of the highest fuel delivery per stroke at the declared maximum torque speed. In the event that two or more engines share this primary criteria, the parent engine shall be selected using the secondary criteria 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 test based upon features which indicate that it may have the highest emission levels of the engines within that family.

7.2. 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.

TEST PROCEDURE FOR C.I. ENGINES

▼B

1. INTRODUCTION

1.1. This Annex describes the method of determining emissions of gaseous and particulate pollutants from the engines to be tested. ▼M3 Two test cycles are described that shall be applied according to the provisions of Annex I, Section 1: — the NRSC (non-road steady cycle) which shall be used for stages I, II and IIIA and for constant speed engines as well as for stages IIIB and IV in the case of gaseous pollutants, — the NRTC (non-road transient cycle) which shall be used for the measurement of particulate emissions for stages IIIB and IV and for all engines but constant speed engines. By the choice of the manufacturer this test can be used also for stage IIIA and for the gaseous pollutants in stages IIIB and IV, — for engines intended to be used in inland waterway vessels the ISO test procedure as specified by ISO 8178-4:2002 [E] and IMO MARPOL 73/78, Annex VI (NOx Code) shall be used, — for engines intended for propulsion of railcars an NRSC shall be used for the measurement of gaseous and particulate pollutants for stage III A and for stage III B, — for engines intended for propulsion of locomotives an NRSC shall be used for the measurement of gaseous and particulate pollutants for stage III A and for stage III B. ▼B

1.2. The test shall be carried out with the engine mounted on a test bench and connected to a dynamometer.

▼M3

1.3. Measurement principle: The engine exhaust emissions to be measured include the gaseous components (carbon monoxide, total hydrocarbons and oxides of nitrogen), and the particulates. Additionally, carbon dioxide is often used as a tracer gas for determining the dilution ratio of partial and full flow dilution systems. Good engineering practice recommends the general measurement of carbon dioxide as an excellent tool for the detection of measurement problems during the test run. 1.3.1. NRSC test: During a prescribed sequence of operating conditions, with the engines warmed up, the amounts of the above exhaust emissions shall be examined continuously by taking a sample from the raw exhaust gas. The test cycle consists of a number of speed and torque (load) modes, which cover the typical operating range of diesel engines. During each mode, the concentration of each gaseous pollutant, exhaust flow and power output shall be determined, and the measured values weighted. The particulate sample shall be diluted with conditioned ambient air. One sample over the complete test procedure shall be taken and collected on suitable filters. Alternatively, a sample shall be taken on separate filters, one for each mode, and cycle-weighted results computed. The grams of each pollutant emitted per kilowatt-hour shall be calculated as described in Appendix 3 to this Annex. 1.3.2. NRTC test: The prescribed transient test cycle, based closely on the operating conditions of diesel engines installed in non-road machinery, is run twice: — The first time (cold start) after the engine has soaked to room temperature and the engine coolant and oil temperatures, after treatment systems and all auxiliary engine control devices are stabilised between 20 and 30 °C. — The second time (hot start) after a twenty-minute hot soak that commences immediately after the completion of the cold start cycle. During this test sequence the above pollutants shall be examined. Using the engine torque and speed feedback signals of the engine dynamometer, the power shall be integrated with respect to the time of the cycle, resulting in the work produced by the engine over the cycle. The concentrations of the gaseous components shall be determined over the cycle, either in the raw exhaust gas by integration of the analyser signal in accordance with Appendix 3 to this Annex, or in the diluted exhaust gas of a CVS full-flow dilution system by integration or by bag sampling in accordance with Appendix 3 to this Annex. For particulates, a proportional sample shall be collected from the diluted exhaust gas on a specified filter by either partial flow dilution or full-flow dilution. Depending on the method used, the diluted or undiluted exhaust gas flow rate shall be determined over the cycle to calculate the mass emission values of the pollutants. The mass emission values shall be related to the engine work to give the grams of each pollutant emitted per kilowatt-hour. Emissions (g/kWh) shall be measured during both the cold and hot start cycles. Composite weighted emissions shall be computed by weighting the cold start results 10 % and the hot start results 90 %. Weighted composite results shall meet the standards. ▼M5 Prior to the introduction of the cold/hot composite test sequence, the Commission shall modify the symbols (Annex I, section 2.18), the test sequence (Annex III) and the calculation equations (Annex III, Appendix 3). Those measures, designed to amend non-essential elements of this Directive, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 15(2).
