Commission Directive 2010/26/EUShow full title

ANNEX I U.K.

The following section 8 is added to Annex I to Directive 97/68/EC:

‘8. TYPE APPROVAL REQUIREMENTS FOR STAGES IIIB AND IV

8.1. This section shall apply to the type-approval of electronically controlled engines, which uses electronic control to determine both the quantity and timing of injecting fuel (hereafter “engine”). This section shall apply irrespective of the technology applied to such engines to comply with the emission limit values set out in sections 4.1.2.5 and 4.1.2.6 of this Annex.

8.2. Definitions

For the purpose of this section, the following definitions shall apply:

8.2.1. “emission control strategy” means a combination of an emission control system with one base emission control strategy and with one set of auxiliary emission control strategies, incorporated into the overall design of an engine or non-road mobile machinery into which the engine is installed.

8.2.2. “reagent” means any consumable or non-recoverable medium required and used for the effective operation of the exhaust after-treatment system.

8.3. General requirements

8.3.1. Requirements for base emission control strategy

8.3.1.1. The base emission control strategy, activated throughout the speed and torque operating range of the engine, shall be designed as to enable the engine to comply with the provisions of this Directive

8.3.1.2. Any base emission control strategy that can distinguish engine operation between a standardised type approval test and other operating conditions and subsequently reduce the level of emission control when not operating under conditions substantially included in the type approval procedure is prohibited.

8.3.2. Requirements for auxiliary emission control strategy

8.3.2.1. An auxiliary emission control strategy may be used by an engine or a non-road mobile machine, provided that the auxiliary emission control strategy, when activated, modifies the base emission control strategy in response to a specific set of ambient and/or operating conditions but does not permanently reduce the effectiveness of the emission control system:

(a)

where the auxiliary emission control strategy is activated during the type approval test, sections 8.3.2.2 and 8.3.2.3 shall not apply;

(b)

where the auxiliary emission control strategy is not activated during the type approval test, it must be demonstrated that the auxiliary emission control strategy is active only for as long as required for the purposes identified in section 8.3.2.3.

8.3.2.2. The control conditions applicable to this section are all of the following:

(a)

an altitude not exceeding 1 000 metres (or equivalent atmospheric pressure of 90 kPa);

(b)

an ambient temperature within the range 275 K to 303 K (2 °C to 30 °C);

(c)

the engine coolant temperature above 343 K (70 °C).

Where the auxiliary emission control strategy is activated when the engine is operating within the control conditions set out in points (a), (b) and (c), the strategy shall only be activated exceptionally.

8.3.2.3. An auxiliary emission control strategy may be activated in particular for the following purposes:

(a)

by onboard signals, for protecting the engine (including air-handling device protection) and/or non-road mobile machine into which the engine is installed from damage;

(b)

for operational safety and strategies;

(c)

for prevention of excessive emissions, during cold start or warming-up, during shut-down;

(d)

if used to trade-off the control of one regulated pollutant under specific ambient or operating conditions, for maintaining control of all other regulated pollutants, within the emission limit values that are appropriate for the engine concerned. The purpose is to compensate for naturally occurring phenomena in a manner that provides acceptable control of all emission constituents.

8.3.2.4. The manufacturer shall demonstrate to the technical service at the time of the type-approval test that the operation of any auxiliary emission strategy complies with the provisions of section 8.3.2. The demonstration shall consist of an evaluation of the documentation referred to in section 8.3.3.

8.3.2.5. Any operation of an auxiliary emission control strategy not compliant with section 8.3.2 is prohibited.

8.3.3. Documentation requirements

8.3.3.1. The manufacturer shall provide an information folder accompanying the application for type-approval at the time of submission to the technical service, which ensures access to any element of design and emission control strategy and the means by which the auxiliary strategy directly or indirectly controls the output variables. The information folder shall be made available in two parts:

(a)

the documentation package, annexed to the application for type-approval, shall include a full overview of the emission control strategy. Evidence shall be provided that all outputs permitted by a matrix, obtained from the range of control of the individual unit inputs, have been identified. This evidence shall be attached to the information folder as referred to in Annex II;

(b)

the additional material, presented to the technical service but not annexed to the application for type-approval, shall include all the modified parameters by any auxiliary emission control strategy and the boundary conditions under which this strategy operates and in particular:

(i)

a description of the control logic and of timing strategies and switch points, during all modes of operation for the fuel and other essential systems, resulting in effective emissions control (such as exhaust gas recirculation system (EGR) or reagent dosing);

(ii)

a justification for the use of any auxiliary emission control strategy applied to the engine, accompanied by material and test data, demonstrating the effect on exhaust emissions. This justification may be based on test data, sound engineering analysis, or a combination of both;

(iii)

a detailed description of algorithms or sensors (where applicable) used for identifying, analysing, or diagnosing incorrect operation of the NO_x control system;

(iv)

the tolerance used to satisfy the requirements in section 8.4.7.2, regardless of the used means.

8.3.3.2. The additional material referred to in point (b) of section 8.3.3.1 shall be treated as strictly confidential. It shall be made available to the type-approval authority on request. The type-approval authority shall treat this material as confidential.

8.4. Requirements to ensure correct operation of NO_x control measures

8.4.1. The manufacturer shall provide information that fully describes the functional operational characteristics of the NO_x control measures using the documents set out in section 2 of Appendix 1 to Annex II and in section 2 of Appendix 3 to Annex II.

8.4.2. If the emission control system requires a reagent, the characteristics of that reagent, including the type of reagent, information on concentration when the reagent is in solution, operational temperature conditions and reference to international standards for composition and quality must be specified by the manufacturer, in section 2.2.1.13 of Appendix 1 and in section 2.2.1.13 of Appendix 3 to Annex II.

8.4.3. The engine emission control strategy shall be operational under all environmental conditions regularly pertaining in the territory of the Community, especially at low ambient temperatures.

8.4.4. The manufacturer shall demonstrate that the emission of ammonia during the applicable emission test cycle of the type approval procedure, when a reagent is used, does not exceed a mean value of 25 ppm.

8.4.5. If separate reagent containers are installed on or connected to a non-road mobile machine, means for taking a sample of the reagent inside the containers must be included. The sampling point must be easily accessible without requiring the use of any specialised tool or device.

8.4.6. Use and maintenance requirements

8.4.6.1. The type approval shall be made conditional, in accordance with Article 4(3), upon providing to each operator of non-road mobile machinery written instructions comprising the following:

(a)

detailed warnings, explaining possible malfunctions generated by incorrect operation, use or maintenance of the installed engine, accompanied by respective rectification measures;

(b)

detailed warnings on the incorrect use of the machine resulting in possible malfunctions of the engine, accompanied by respective rectification measures;

(c)

information on the correct use of the reagent, accompanied by an instruction on refilling the reagent between normal maintenance intervals;

The instructions shall be written in a clear and non-technical manner using the same language as is used in the operator’s manual on non-road mobile machinery or engine.

8.4.7. Reagent control (where applicable)

8.4.7.1. The type approval shall be made conditional, in accordance with the provisions of section 3 of Article 4, upon providing indicators or other appropriate means, according to the configuration of the non-road mobile machinery, informing the operator on:

(a)

the amount of reagent remaining in the reagent storage container and by an additional specific signal, when the remaining reagent is less than 10 % of the full container’s capacity;

(b)

when the reagent container becomes empty, or almost empty;

(c)

when the reagent in the storage tank does not comply with the characteristics declared and recorded in section 2.2.1.13 of Appendix 1 and section 2.2.1.13 of Appendix 3 to Annex II, according to the installed means of assessment.

(d)

when the dosing activity of the reagent is interrupted, in cases other than those executed by the engine ECU or the dosing controller, reacting to engine operating conditions where the dosing is not required, provided that these operating conditions are made available to the type approval authority.

8.4.7.2. By the choice of the manufacturer the requirements of reagent compliance with the declared characteristics and the associated NO_x emission tolerance shall be satisfied by one of the following means:
