1 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues WLTP-DTP-AP Status Report and Open issues

2 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Status Evaluation of VP2 results is mostly done NO2: Measurement method for NO2 could be confirmed Open issues regarding NO2 could be answered N2O: Not sufficient data for evaluation No open issues NH3: Not sufficient data for evaluation Remaining open issues ETOH and Aldehydes Not part of VP2 Separate validation required

3 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Open issues: NH3-Measurement Issue: – Measurement from raw exhaust influences subsequent CVS measurements – Not sufficient results from VP2 Available Proposals: 1.Limit sample flow and return bypass (  influence on small displacements may still be too high) 2.Additional test for NH3 (  workload) 3.Measurement from diluted exhaust (  so far no experience, difficulties expected)

4 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Necessary for decision: – Postpone finalization of GTR for NH3 measurement till end of 2013 Way out: – Evaluation of diluted measurement – Include in AP validation Sept 2013 Open issues: NH3-Measurement

5 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Open issues: N2O-Measurement Issue: – No technical issues foreseen – But not sufficient results from VP2 – In industry evaluation has been performed Way out: – Use data from industry programs to validate draft GTR

6 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Open issues: Measurement of EtOH and Aldehydes Issue: – No data from VP2 – New measurement methods not yet available Necessary for decision: – Postpone finalization of GTR for EtOH and Aldehydes measurement till end of 2013 Way out: – Validation will be performed separately in Sept. 2013

7 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues Next Steps 1 Telephone Conference: NH3-Measurement Date: 5 th of February Topic: Next steps to resolve open issue: Measurement from raw exhaust influences subsequent CVS measurements 2. Face to Face meeting: Preparation of Validation Exercise Date: 7th to 8th of March Goal: Definition of measurement program, participating instruments, vehicles, test procedure 3. AP-Validation exercise Date: Sept Ispra Duration 3 weeks Goal: Validation of EtOH and Aldehydes measurement, possibly NH3 to be included

8 WLTP-DTP-AP, Mörsch/Astorga WLTP-DTP Subgroup Additional Pollutants DTP12 - Status Report and Open Issues No data from VP2 Additional measurement campaign necessary At least two weeks, ca. sept (depending on availability of instruments) JRC will host Instrument manufacturers methods: – AVL – Horiba – Innova (to be verified) – MAHA – Sensors GC-Method FTIR Call for instruments (on CIRCA) Vehicles: 2 different FFV, 2 Gasoline Validation of measurement of EtOH and Aldehydes
