3 MAW CO 2 based method The conformity factors (CF) are calculated for each individual window and each individual pollutant in the following way: CFI CF CF C CF I CF C m m CO CO 2, m m L 2, ref ref (in-service ratio) (certification ratio) m is the mass emission of the component, g/window m CO, ref 2 is the engine CO 2 mass measured on the NRTC m L is the mass emission of the component corresponding to the applicable limit on the WHTC, expressed in grams.

4 How is the applicable limit on the NRTC, expressed in grams/kwh relates to? m L In Stage IV the NOx limit is 0.4 g/kwh, then W ref is the engine work for the NRTC, kwh Other conditions: m 0. 4 L W ref The valid windows are the windows whose duration does not exceed the threshold duration calculated from: Where: D max Wref P max D max P max is the maximum allowed window duration, s is the maximum engine power, kw

11 Introduction and Background EURO V standards for HD engines requires to verify the conformity with the applicable emissions certification standards ISC The above route was followed for non-road engines as well: preliminary research activities studied and confirmed the possibility to apply the methods developed for heavy-duty engines with minor modifications.

12 The basis for the introduction of ISC (ISM) provisions based on the PEMS approach into the European NRMM type-approval legislation has been established in several texts. Amongst these texts, the Directive 2004/26/EC NRMM PEMS Pilot Program ( ) 1.studied the introduction into the European NRMM emissions legislation of the use of PEMS as a tool for ISC 2.focused on the use of PEMS for Stage IIIB variable speed compression-ignition engines in the power range kW, installed in land-based NRMM or agricultural and forestry tractors. (Stage IIIA or stage IV engines were also included) Directive 2004/26/EC of the European Parliament and of the Council of 21 April 2004 amending Directive 97/68/EC 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

13 Objectives and Scope 1. It shall help to implement the provisions contained in the new legislative NRMM proposal with respect to the monitoring of emissions of in-service engines. 2. It shall propose appropriate technical procedures for the relevant measurement methods and increase the awareness of the different stakeholders for this new regulatory tool 3. This pilot program applies to in-service engines installed in land-based NRMM in the power ranges <56kW and >560kW, as well as to those installed in inland waterway vessels and rail vehicles.

14 Project organisation European Commission: DG GROW acting in co-operation with the JRC sets up the "Pilot Programme for testing in-service engines in NRMM" and will ensure its general co-ordination. o DG GROW will primarily steer the programme, co-ordinate related activities and organise meetings and technical seminars. o JRC will provide the technical support Member State authorities will support technical services in the execution of in-field tests and will provide expertise based on their type-approval experience.

15 Project organisation (cont.) Technical services will conclude appropriate tests in co-operation with machine and engine manufacturers. Engine manufacturers locate and provide the test machines and, to the maximum extent possible, the necessary equipment for the testing activities. NRMM manufacturers are strongly encouraged to join the programme. In most cases they are likely to do so indirectly by working with an engine manufacturer. PEMS equipment manufacturers will be involved in the programme so as to receive feedback to help improve PEMS equipment before the launch of any official testing requirements.

16 Project organisation (cont.) Dissemination of information: The GEME CIRCABC website set up by DG ENTR will provide access to the documents related to the "Pilot Programme for testing in-service engines in NRMM". COM will organise meetings on a regular basis during the "Pilot Programme to encourage the exchange of information and effective co-operation of the participants Financing: The "Pilot Programme for testing in-service engines in NRMM" shall be primarily financed by the participants. COM contributes directly through the technical support of the JRC. Timing: it will start early 2016 and last until December It includes: a preparatory campaign (>560 kw) consisting of experimental and/or data-collection activities.

17 Project deliverables Consolidated test protocols for the measurement of gaseous emissions of in-service engines, both for in-field tests and in-service tests of extracted engines Test data reports following the completion of in-field tests and for inservice tests of extracted engines (technical services, manufacturers), upon agreement of the contracting parties. A final technical report, compiling the various studies that may be conducted on the following topics: (Updated) installation recommendations of PEMS equipment on various types of machines; Guidance and recommendations for measurement procedures of extracted engines; The data evaluation method and its settings. (E.g. calculation parameters, valid and invalid test data, or averaging windows).
