GTR 2: Amendment 4 as approved by GRPE
Document GRPE/79/Add.1
15 July 2019

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

  1. reference fuels
  2. temperature conversion
  3. forced induction systems (turbo/super-chargers)
  4. treatment of open/closed systems
  5. test room humidity
  6. CO2 tolerance, and
  7. reference mass of the vehicle.
