2 WLTP-DTP Subgroup Additional Pollutants September 2011 NO 2 VALIDATION PHASE 2 SHOULD INCLUDE NO 2 MEASUREMENTS NH 3 Row measurements difficult to implement right now N 2 O Sampling devices not yet available/mature Ethanol (EtOH) and Aldehydes: Formaldehyde, Acetaldehyde (RCHO, R = H or Me) Only relevant for Flex fuel vehicles (not part of validation 2) Pollutants to be addressed during phase 2?

3 WLTP-DTP Subgroup Additional Pollutants September 2011 1.NO 2 Performance criteria and list of parameters will be provide by coordinator 2.NO 2 criteria should be based on NOx (e.g. variability max twice the variability of Nox; Criteria must also depend on absolute value) 3.Ref document WLTP-DTP-02-06e.doc (available on CIRCA).

4 WLTP-DTP Subgroup Additional Pollutants September 2011 Parameter setting lists overview of the test procedure: will be based on gtr doc Gathering the required information with respect to performance criteria has been tasked within group. Delivery of Data format for exchange for NO2

5 WLTP-DTP Subgroup Additional Pollutants September 2011 Drafting of GTR for reference methods [*] NO 2 and NH 3 based on OICA proposals N 2 O, Ethanol and Aldehydes based on existing legislation Gathering of performance data for candidate methods Tasks have been assigned within group and will be performed until next meeting. Work on going [*] Draft GTR proposal: WLTP-DTP-LabProcICE-061
