They shall be tuned properly and set to the manufacturer’s specification prior to emission testing. For the purposes of points b and c of paragraph 3. For the purposes of point c of paragraph 3.

In order to receive a type approval of an engine system or engine family as a separate technical unit, type approval of a vehicle with an approved engine system with regard to emissions, or a type approval of a vehicle with regard to emissions, the manufacturer shall, in accordance with the provisions of ecw Regulation demonstrate that the vehicles or engine systems are subject to the tests and comply with the requirements set out in paragraph 5.

The manufacturer shall also ensure exe with the specifications of reference fuels set out in Annex 5. In order to receive type approval of a vehicle with an approved engine system with regard to emissions or a type approval of a vehicle with regard to emissions the manufacturer shall ensure compliance with the installation requirements set out in paragraph 6.

In order to receive a type approval of a dual-fuel engine or engine family as a separate technical unit, type approval of a dual-fuel vehicle with an approved dual-fuel engine with regard to emissions, or a type approval of a dual-fuel vehicle with regard to emissions, the manufacturer shall, in addition to the requirements of paragraph 4.

In order to receive a type approval of an engine system or engine family as a separate technical unit or a type approval of a vehicle with regard to emissions, the manufacturer shall ensure compliance with the requirements on fuel range for a universal fuel approval or in case of a positive ignition engine fuelled with natural gas and LPG a restricted fuel range approval as specified in paragraph 4.

A universal fuel range approval shall be granted subject to the requirements specified in paragraphs 4.
