|
Reference Number: WP.29/2019/121
|
|
Proposal to further harmonize test procedures for two-wheeled vehicles equipped with conventional combustion engine technology, including restructuring to dedicate separate sections to test types I (tailpipe emission after cold start), II (idle / free acceleration emissions) and VII (energy efficiency). The amendment aligns the GTR with technological progress, including changes related to - reference fuels
- temperature conversion
- forced induction systems (turbo/super-chargers)
- treatment of open/closed systems
- test room humidity
- CO2 tolerance, and
- reference mass of the vehicle.
