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.

Proposal for Regulation for retrofit after-treatment systems for engines used in non-road mobile machinery and agricultural tractors with respect to the emissions of pollutants

The Netherlands proposes to initiate a working group with the aim to develop harmonized quality criteria and a type approval scheme, which would be acceptable as an alternative for existing retrofit schemes, and which could be used by countries all over the world considering to introduce retrofitting of existing diesel engines with particulate traps.
