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. Motor Vehicle Emissions Motor Vehicle Emissions UN Regulation No. 83 UN R83, and Uniform Provisions Concerning the Approval of Compression-Ignition (C.I.)
