Proposals to inhibit tampering with emissions systems and to facilitate detection of such tampering.

OICA request for clarification on the interpretation of Supplement 6 to the 07 series of amendments to UN R83 which enables the use of compliance assessments of vehicles with a reference mass less than 2,610 kg for the purposes of extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg.

Proposal to clarify “permanent default” and “limp-home mode” in UN R83.

Proposal to amend current definitions to allow fault code erasing in cold regions (< -7°C) and high altitude (> 2440m), harmonizing the definitions with those used in China and the United States.

Proposal to allow for the use of use special denominator conditions for certain components or systems. The current definitions of the specific denominators are based on engine/aftertreatment system combinations designed as one TWC for gasoline vehicles and DOC, DPF and SCR respectively NSC for diesel engines. Upcoming emission requirements will bring up additional aftertreatment components like Gasoline Particulate Filters (GPF) or new designs with more than one SCR catalyst. Such new systems or catalyst combinations might require specific conditions to enable the monitoring, especially when their purpose is designed for such conditions.
