PROPOSAL FOR SUPPLEMENT 8 TO THE 06 SERIES OF
AMENDMENTS TO
REGULATION NO. 83
(EMISSIONS OF M 1 AND N 1 VEHICLES))
ADOPTED AT THE 170 SESSION – NOVEMBER 2016
PROVISIONAL DATE OF ENTRY INTO FORCE: JUNE 22, 2017

Annex 11,
Paragraph 3.3.3.1., amend to read:
"3.3.3.1. The reduction in the efficiency of the catalytic converter with respect to emissions of
NMHC and NO . Manufacturers may monitor the front catalyst alone or in combination with
the next catalyst(s) downstream. Each monitored catalyst or catalyst combination shall be
considered malfunctioning when the emissions exceed the NMHC or NO threshold limits
provided for by Paragraph 3.3.2. of this Annex. By way of derogation the requirement of
monitoring the reduction in the efficiency of the catalytic converter with respect to NO
emissions shall only apply as from the dates set out in Paragraph 12.1.4."
Paragraph 3.3.3.4., amend to read:
"3.3.3.4. If active on the selected fuel, other emission control system components or systems, or
emission related power train components or systems which are connected to a computer,
the failure of which may result in tailpipe emissions exceeding the OBD threshold limits
given in Paragraph 3.3.2. of this Annex."
Paragraph 3.3.4.4., amend to read:
"3.3.4.4. Other emission control system components or systems, or emission-related power-train
components or systems, which are connected to a computer, the failure of which may
result in exhaust emissions exceeding the OBD threshold limits given in Paragraph 3.3.2.
of this Annex. Examples of such systems or components are those for monitoring and
control of air mass-flow, air volumetric flow (and temperature), boost pressure and inlet
manifold pressure (and relevant sensors to enable these functions to be carried out)."
Paragraph 3.3.5., amend to read:
"3.3.5. Manufacturers may demonstrate to the Type Approval Authority that certain components
or systems need not be monitored if, in the event of their total failure or removal,
emissions do not exceed the OBD threshold limits given in Paragraph 3.3.2. of this
Annex."
