Co-Decision part of the legislation to be finalised by end April 2014 with delegated Act to be adopted in 18-24 months on the test methods and other practical aspects.
Co-Decision part will contain the essential elements – i.e scope and limit values
PN limit values will be established for: - 56 – 560 kW : land based engines
- >300 kW : inland waterway transport
- All rail cars (note locomotives out of scope)
Mr Troppmann (DG-ENTR) confirmed that EU Com very keen on PMP activities. Have contracted JRC to study but 1-2 engines required, timing preparation until end 2014, testing during 1st half 2015.
Proposal as per Swiss ordinance : 1E+12 #/kWh – in line with PM limits as tried to correlate stringency of PM and PN limits.
J Andersson (Ricardo AEA) presented overview of NRMM situation and open questions – - eg Slide 11 – considering partial flow measurement instead of CVS
- Open crankcase ventilation issues (slide 12) with oil mist via mini CVS to prevent damage to measurement side by analyser contamination. Noted blow-by gas measurement already required.
- Areas for further study identified on slide 17.
Discussion of HD Euro 6 idea to move to raw PN measurement with extra fixed dilution stage prior to PND1. Not confirmed if this proposal is being taken forward.- <56kW : PN will apply for CI engines only
- >56kW : PN will apply to both CI and SI engines
- Questions remain on CNG SI and CNG CI dual fuel engines
- Fuel = 10 ppm S
