Article 2 Application for certification of CO2 savings
United Kingdom
A manufacturer may apply for certification of the CO2 savings from one or several 12 Volt (V) efficient alternators intended for use in N1 vehicles, provided that each alternator is a component used solely to charge the vehicle battery and to power the electrical system of the vehicle when its combustion engine is running and complies with either of the following conditions:
where the mass of the 12 V efficient alternator does not exceed the mass of the baseline alternator of 7 kg, the efficiency of the alternator, determined in accordance with the Annex, shall be at least:
- (i)
73,8 % for petrol-fuelled vehicles;
- (ii)
73,4 % for petrol turbo-fuelled vehicles;
- (iii)
74,2 % for diesel-fuelled vehicles;
where the mass of the 12 V efficient alternator exceeds the mass of the baseline alternator of 7 kg, the vehicle fitted with this alternator shall meet the minimum reduction threshold of 1 g CO2/km specified in Article 9(1)(a) of Implementing Regulation (EU) No 427/2014; that reduction shall be determined taking into account the extra mass according to Formula 10 set out in the Annex to this Decision; the extra mass shall be verified and confirmed in the verification report to be submitted to the type approval authority together with the application for certifications.
An application for the certification of the savings from one or several efficient alternators shall be accompanied by an independent verification report certifying that the alternator or alternators comply with the conditions set out in paragraph 1, and verifying and confirming the mass of the alternator.
The type approval authority shall reject the application for certification if it finds that the alternator or alternators do not comply with the conditions set out in paragraph 1.
