WMTC World-wide Motorcycle Emissions Test Cycle

Detailed proposal for the development of a global motorcycle emissions test cycle aimed at harmonizing regulations and standards worldwide. The document covers technical issues, test protocols, targets, regulations/standards overview, informal group details, test cycle data collection, gearshift procedure, validation steps, and performance requirements discussions. It also outlines the next steps for the project, including meetings, reports, and considerations for limit values, additional requirements, cost/benefit analysis, and enforcement processes. The proposal was presented at the UN-ECE-WP.29 in Geneva on November 13, 2003.

  1. WMTCWorld-wide Motorcycle Emissions Test Cycle Proposal to develop a WMTCGTR UN-ECE-WP.29, Geneva, 13. November 2003

  2. WMTCWorld-wide Motorcycle Emissions Test Cycle • TRANS/WP.29/2003/103 • Technical issues of WMTC • Outlook on performance requirements UN-ECE-WP.29, Geneva, 13. November 2003

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

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

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

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

  7. WMTC –Informal group • Start 1999 (VROM, TNO, IMMA)(since 2000 joined by RWTÜV) • WMTC informal group Members:GovermentsNGO‘s EC Germany IMMAJapan Netherlands AECCSpain SwitzerlandUK USA

  12. WMTC –Gearshift procedure

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

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

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

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

  17. WMTC– Performance requirements • (2) Additional requirements • Evaporative emissions, CO2 , COP,CO idle test, Durability, Off cycle emissions, … • What should be included in the draft GTR (first step)

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

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