Particle Measurement Programme | Session 28 | 21 Nov 2013
Brussels
Agenda Item 5.
Particle emissions from NRMM

20. EU Com (Mr Troppman ) gave a brief overview of the regulatory activities on NRMM PN. New NRMM impact assessment being completed – extension of scope of NRMM to additional power categories, inclusion of large LNG engines, adaptation of limit values particle number – similar to EU 6 heavy duty. EU Com needs a limit value for impact assessment – have looked at data for HD, non-road etc and determined a value of 1E+12 #/kWh for the impact assessment and most likely this will be carried into the draft proposal. This has raised some concern with EU Com internally. There is still a need for an experimental program, not only for this rule making but for the next revision clause.

21. EUROMOT (Paul Williams) presented some principles for NRMM PMP program. He briefly introduced EUROMOT as a new stakeholder to PMP. Essentially there are 40 member companies; in simple terms this covers a vast array of engines including everything which moves without a licence plate and everything which generates heat and power.

22. EUROMOT expressed willingness to participate and identified the need for EU Com /JRC to take care of proper systems and testing – as this measurement is rather new. EUROMOT also requested EU Com to allow manufacturers in house data to be incorporated. Need to identify subject engines and test cycles.

  • Specific attention must be paid to passive regeneration during test.
  • Need to check both discrete and RMC (ramped modal cycle). On RMC need to take as much as possible from PN ECE-49-06.

23. EU Com mentioned that Co-Decision will start once the new Commission is in place during 2014 and therefore the data from the NRMM PN test program should be available to support this timing.

  • Paul Williams (EUROMOT) reminded that rolling out Euro 4 during 2014 and their facilities are very busy.
  • JRC (GM) mentioned they have some possibilities for testing but already they are also busy and won’t be able to install many engines.
  • AECC noted also made some testing back in 2010 and would like to contribute. Paul Williams noted that the AECC testing was one engine / one size.
  • Ricardo reminded of the need to use partial flow systems and that there is a good correlation between full and partial flow.
  • Euro 3 engines with DPF tested but not the real Euro 4 engines – where there is a different proportion of manufacturers using passive regeneration.
  • Clear R49.06 should be the basis but the next aspect is test cycles – transient vs. steady, engine power and technologies etc.

24. EU Com / JRC Giorgio will prepare a draft outline of the test program and then share with the group during the next PMP Jan GRPE.
