Overview of current US Environmental Protection Agency heavy-duty hybrid powerpack testing activites.

Draft new Regulation on uniform provisions concerning the approval of specific LPG (liquefied petroleum gases) or NG (compressed natural gas/bio-methane/liquefied natural gas) dual fuel retrofit systems to be installed in heavy duty vehicles, agricultural and forestry tractors and non road mobile machinery equipped with Compression Ignition engines

GRPE-approved text to align the requirements of UN R101 with those of EU Regulation (EC) Nos. 459/2012 and 630/2012.

GRPE-approved proposal to align the requirements of UN R103 with those of EU Regulation (EC) Nos. 459/2012 and 630/2012.

GRPE-approved text, based on a proposal prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.

Proposal for a new Regulation on uniform provisions concerning the approval of Retrofit Emission Control Devices (REC) for heavy duty vehicles, agricultural and forestry tractors and non-road mobile machinery equipped with compression-ignition engines

Discussion items for the 16th REC session concerning stringency requirements and safeguards against reversing particulate filters.

Planned schedule for reaching approval of the new UN Regulation on retrofit emissions control devices and its second phase amendment.

Agenda for the special GRPE session intended to finalize the draft GTR Worldwide Light vehicle Test Procedure (WLTP) to establish uniform light vehicle emissions and fuel efficiency test procedures.

The main objective of this proposal is to establish an amendment to global technical regulation No. 2 on the Worldwide harmonized Motorcycle emissions Certification-test procedure (WMTC) to insert Environmental and Propulsion Performance Requirements (EPPR), currently only applicable for two-wheeled motorcycles. Should an amendment to GTR No. 2 be deemed inappropriate, alternatives including development of a new GTR will be considered.

The objectives also include development of requirements and/or test procedures to create synergies and uniform provisions with related 1958 Agreement UN Regulations, exchange information on current and future regulatory EPPR, e.g. for
“category 3 vehicles” or “L-category vehicles”, minimize differences between these regulatory EPPR, with the view to facilitate the development of light vehicles complying with such internationally harmonized requirements, and to assess coherence with other regulatory requirements and groups activities, such as those on Worldwide harmonized Light vehicles Test Procedures (WLTP) and on Electric Vehicles and the Environment (EVE).

Proposal to correct provisions concerning permissions to disable OBD system monitors during testing under certain altitude and temperature conditions contained in the proposal to revise the 06 series of amendments to UN R49.

Proposal was prepared by the secretariat to correct a typographical error in the unit of the diameter of particulates in the 06 series of amendments:

Page 7, paragraph 2.5.1., for “23 mm” read “23 nm”.

Overview and update on the proposed new regulation on retrofit dual-fuel systems for heavy-duty vehicles.

Initial draft version of the new Regulation on “uniform provisions concerning the approval of specific LPG (liquefied petroleum gases) or NG (compressed natural gas/bio-methane/liquefied natural gas) dual fuel retrofit systems and dual fuel retrofitted engines to be installed in heavy duty applications”.

Position paper calling attention to transport-related particulate matter, including exhaust and non-exhaust particulates, and considering the negative impact on air quality inside motor vehicles due to shortcomings in ventilation and filtration systems.
