Engines and Positive-ignition (P.I.) Engines Fuelled with Natural Gas (NG) or Liquefied Petroleum Gas (LPG) with regard to the Emission of Pollutants The Informal Group on Heavy-Duty Hybrids expects to deliver its final draft amendment to GTR No.4 at the January 2014 session of GRPE. This amendment would extend GTR No. 4 to include test procedures to evaluate hybrid heavy-duty vehicles. WHDC Worldwide Heavy-Duty Vehicle Emissions Certification Procedure GTR No. 4 GTR No. 4, Technical requirements for on-board diagnostic systems (OBD) for road vehicles OBD On-Board Diagnostic Systems GTR No. 5 GTR No. 5, Off-cycle emissions OCE Off-Cycle Emissions GTR No. 10 GTR No. 10, Test procedure for compression-ignition engines to be installed in agricultural and forestry tractors and in non-road mobile machinery with regard to the emissions of pollutants by the engine NRMM Emissions Non-Road Mobile Machinery Emissions GTR No. 11 GTR No. 11, Worldwide Harmonized Light Vehicles Test Procedure

This GTR prescribes a test cycle and test procedures to measure the emissions (including off-cycle) and fuel efficiency of light-duty vehicles. The GTR was adopted at the March 2014 session of the World Forum.

A supplemental "phase 1b" is underway to refine certain elements of the initial regulation. WP.29/AC.3 expects to consider a proposal for Amend. 1 to UN GTR No. 15 in November 2016 as result of Phase 1b activities.

A second phase is expected to address low ambient temperature, high altitude test procedures, and possibly durability and conformity issues.

A third phase would eventually include the addition of reference fuels, correlation across existing regional/national cycles, and introduction of emissions limits.

The latest draft version of the amended GTR is regularly updated by the WLTP informal working group.

The regulation is also supplemented by a gearshift calculation tool.

R83 covers emissions from all light vehicles (M1/N1) regardless of engine type and from heavier vehicles only if equipped with a gasoline engine. Under certain circumstances, R83 or R49 can apply to light vehicle CNG/LPG engines as well as to medium passenger and commercial vehicles (M2/N2) equipped with diesel engines. R83 also contains provisions specific to hybrid variations of the vehicles under its purview.
