OICA proposes the development of a global technical regulation for certification of HEV. The proposal aims to provide a test procedure and harmonized technical requirements for HEV emissions certification. The proposal is focused on emissions certification rather than on fuel consumption or CO2 certification. OICA further proposes that the regulation should be based on the HILS approach, which starts from a vehicle cycle and simulates powertrain and vehicle components to come up with an engine cycle for emissions testing and measurement.

Comments and recommendations concerning the ‘extended HILS’ approach and application of the current worldwide heavy-duty vehicle emissions test cycle to hybrid vehicles.

OICA contributions to the development of the heavy-duty hybrids amendment to GTR No. 4 (Worldwide Heavy-Duty Vehicle Emissions Certification Procedure).

Presentation concerning heavy-duty hybrids.

Discussion of vehicle characteristics to be taken into account (or left out) in order to ensure an optimally harmonized set of heavy-duty vehicle test procedures for worldwide use.

Proposal to align the draft Amendment with the harmonized terminology and definitions developed by the informal group on Vehicle Propulsion System Definitions.
