Commission Regulation (EU) No 582/2011 of 25 May 2011 implementing and amending Regulation (EC) No 595/2009 of the European Parliament and of the Council with respect to emissions from heavy duty vehicles (Euro VI) and amending Annexes I and III to Directive 2007/46/EC of the European Parliament and of the Council (Text with EEA relevance) (c. 582)

ANNEX V U.K. VERIFYING EMISSIONS OF CRANKCASE GASES

3. SPECIFIC REQUIREMENTS U.K.

[F1 3.1. Point 3.1.1. and 3.1.2. shall apply to compression-ignition engines, dual-fuel engines and to positive-ignition engines fuelled with natural gas/biomethane or LPG. U.K.

3.1.1. Engines equipped with turbochargers, pumps, blowers, or superchargers for air induction may discharge crankcase emissions to the ambient atmosphere if the emissions are added to the exhaust emissions (either physically or mathematically) during all emission testing in accordance with paragraph 6.10 of Annex 4 to UNECE Regulation No 49.] U.K.

3.1.2. Crankcase emissions that are routed into the exhaust upstream of any exhaust after-treatment device during all operation are not considered to be discharged directly into the ambient atmosphere. U.K.

Textual Amendments

F1 Substituted by Commission Regulation (EU) No 133/2014 of 31 January 2014 amending, for the purposes of adapting to technical progress as regards emission limits, Directive 2007/46/EC of the European Parliament and of the Council, Regulation (EC) No 595/2009 of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance).

3.2. Points 3.2.1 and 3.2.2 shall apply to positive-ignition engines fuelled with petrol or E85. U.K.

[F1 3.2.1. The pressure in the crankcase shall be measured over the emission test cycles at an appropriate location. It shall be measured at the dip-stick hole with an inclined-tube manometer.] U.K.

[F2 3.2.1.1. The pressure in the intake manifold shall be measured to within ± 1 kPa. U.K.

Textual Amendments

F2 Inserted by Commission Regulation (EU) No 133/2014 of 31 January 2014 amending, for the purposes of adapting to technical progress as regards emission limits, Directive 2007/46/EC of the European Parliament and of the Council, Regulation (EC) No 595/2009 of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance).

3.2.1.2. The pressure measured in the crankcase shall be measured to within ± 0,01 kPa.] U.K.

3.2.2. Compliance with point 2.1 shall be deemed satisfactory if, in every condition of measurement set out in point 3.2.1, the pressure measured in the crankcase does not exceed the atmospheric pressure prevailing at the time of measurement. U.K.
