ANNEX IIU.K.

ANNEX VIMeasurement of smoke opacity

1.INTRODUCTIONU.K.

1.1.This Annex describes the requirements for measuring the opacity of exhaust emissions from compression ignition engines.U.K.

2.SYMBOL OF THE CORRECTED ABSORPTION COEFFICIENTU.K.

2.1.A symbol of the corrected absorption coefficient shall be affixed to every vehicle conforming to a vehicle type to which this test applies. The symbol shall be a rectangle surrounding a figure expressing in m–1 the corrected absorption coefficient obtained, at the time of approval, from the test under free acceleration. The test method is described in section 4.U.K.
2.2.The symbol shall be clearly legible and indelible. It shall be fixed in a conspicuous and readily accessible place, the location of which shall be specified in the Addendum to the type-approval certificate shown in Annex VI to Directive 2005/55/EC of the European Parliament and the Council(1).U.K.
2.3.Figure 1 gives an example of the symbol.U.K.

1.1.This appendix describes the procedure for the test, measuring carbon monoxide emissions at idling speeds (normal and high).U.K.
1.2.At normal engine idling speed, the maximum permissible carbon monoxide content in the exhaust gases is that stated by the vehicle manufacturer. However, the maximum CO content shall not exceed 0,3 % volume. At high idle speed, the carbon monoxide content by volume of the exhaust gases shall not exceed 0,2 %, with the engine speed being at least 2 000 min–1 and Lambda being 1 ± 0,03 in accordance with the manufacturer's specifications.U.K.

2.2.The manufacturer shall complete the table set out in Annex VI to Directive 2005/55/EC based on the requirements set out in point 2.1.U.K.
2.3.The manufacturer shall confirm the accuracy of the Lambda value recorded at the time of type-approval in section 2.1 as being representative of typical production vehicles within 24 months of the date of the granting of type-approval by the technical service. An assessment shall be made on the basis of surveys and studies of production vehicles.U.K.

3.TECHNICAL REQUIREMENTSU.K.
