WMTC – GTR proposal n TRANS/WP. 29/2003/103 n Proposal to develop a GTR - 1998 agreement n Regarding worldwide harmonised motorcycle emissions test procedure n Informal group WMTC n Technical sponsor: Germany 3

WMTC – Main items n Test cycle n Gearshift procedure n Test protocol (sampling, measurement, analysis – procedures; cooporation with ISO) 4

WMTC – Targets n Improved test cycle Reflects real world onroad motorcycle operation and enables testing of existing and future engine-/ aftertreatment-technologies n Harmonised test procedure Enables worldwide operating manufacturers to delevop motorcycles economically efficient regarding emission requirements 5

WMTC – Regulations/Standards Overview of existing regulations / standards n EU directive 97/24/EC Japanese Reg. TRIAS UN-ECE-R 40 USA – FTP n ISO Standards n n n 6

WMTC – Informal group n Start 1999 (VROM, TNO, IMMA) (since 2000 joined by RWTÜV) n WMTC informal group Members: Goverments EC Germany Japan Netherlands Spain Switzerland UK USA NGO‘s IMMA AECC 7

WMTC – Gearshift procedure 12

WMTC – Validation n Drivebility tests (Modifications of test cycle) n Validation (53 data sheets): n n Comparison WMTC to existing cycles Different laboratories Different motorcycles (e. g. 2/4 -stroke, catalyst) Round robin test n 3 motorcycles – each tested at different laboratories 13

WMTC – Further steps n n n Next informal group meeting 11/03 Results presented to GRPE 1/04: n Final draft Technical report (including round robin test results, final details on weighting and classification) n Amended draft GTR-text without performance requirements Discussion paper to GRPE on options for performance requirements in a WMTC GTR 14

WMTC – Performance requirements n Issues to be discussed concerning performance requirements in a WMTC GTR (1) Limit values (2) Additional requirements (3) Cost/Benefit Analysis (4) Enforcement Process n Type approval n Self certification 15

WMTC – Performance requirements n (1) Limit values (CO, HC, NOx) n option 1: Worldwide most restrictive level (effect: a motorcycle can be accepted all over the world) n option 2: Table with different levels (A, B, C, …) of limit values (effect: contracting party can choose a level) n option 3: ? ? 16

WMTC – Performance requirements n (2) Additional requirements n Evaporative emissions, CO 2 , COP, CO idle test, Durability, Off cycle emissions, … n What should be included in the draft GTR (first step) 17

WMTC – Performance requirements n (3) Cost benefit analysis n Qualitative n Who or quantitative ? can deliver data or information ? 18

WMTC – Performance requirements n (4) Enforcement process Self certification / Type approval n option 1: Issue not included in WMTC GTR n option 2: Annexes in WMTC – GTR -- Annex „x“: Type approval -- Annex „y“: Self certification n option 3: ? ? 19
