Appendix 1

Provisions on CO₂ emissions and fuel consumption for extension of an EC type-approval for a vehicle type approved under Regulation (EC) No 595/2009 and this Regulation with a reference mass exceeding 2 380 kg but not exceeding 2 610 kg U.K.

1. INTRODUCTION U.K.

1.1. This Appendix sets out the provisions and test procedures for reporting CO₂ emissions and fuel consumption for extension of an EC type-approval for a vehicle type approved under Regulation (EC) No 595/2009 and this Regulation to a vehicle with a reference mass exceeding 2 380 kg but not exceeding 2 610 kg. U.K.

2. GENERAL REQUIREMENTS U.K.

2.1. In order to receive an extension of an EC type-approval for a vehicle in respect of its engine type approved under this Regulation to a vehicle with a reference mass exceeding 2 380 kg but not exceeding 2 610 kg the manufacturer shall meet the requirements of Annex XII to Commission Regulation (EC) No 692/2008(1) with the exceptions specified below. U.K.

2.1.1. Section 2.2.1 of Annex XII to Regulation (EC) No 692/2008 shall be understood as referring to the reference fuels described in Annex IX. U.K.

2.1.2. Section 5.2.4 of UN/ECE Regulation 101 referred to in point 2.3 of Annex XII to Regulation (EC) No 692/2008 shall be understood as follows: U.K.

(1)

density: measured on the test fuel according to ISO 3675 or an equivalent method. For petrol, diesel, ethanol (E85) and ethanol for dedicated C.I. engines (ED95) the density measured at 288 K (15 °C) shall be used; for LPG and natural gas/biomethane a reference density will be used, as follows:

• 0,538 kg/litre for LPG.

• 0,654 kg/m³ for NG.

(2)

hydrogen-carbon-oxygen ratio: fixed values shall be used which are:

• C₁H_1,93O_0,032 for petrol (E10),

• C₁H_1,86O_0,006 for diesel (B7),

• C₁H_2,525 for LPG (liquefied petroleum gas),

• CH₄ for NG (natural gas) and biomethane,

• C₁H_2,74O_0,385 for ethanol (E85),

• C₁H_2,92O_0,46 for ethanol for dedicated C.I. engines (ED95).

2.1.3. Point 1.4.3 of Annex 6 to UN/ECE Regulation 101 referred to in Section 3.3 of Annex XII to Regulation (EC) No 692/2008 shall be understood as: U.K.

‘1.4.3.

The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG, ethanol (E85 and ED95) and diesel) or in m³ per 100 km (in the case of NG/biomethane) is calculated by means of the following formulae:

(a)

for vehicles with a positive-ignition engine fuelled with petrol (E10):

FC = (0,120/D) · [(0,831 · HC) + (0,429 · CO) + (0,273 · CO₂)]

(b)

for vehicles with a positive-ignition engine fuelled with LPG:

FC_norm = (0,1212/0,538) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO₂)]

If the composition of the fuel used for the test differs from the composition that is assumed for the calculation of the normalised consumption, on the manufacturer’s request a correction factor cf may be applied, as follows:

FC_norm = (0,1212/0,538) · (cf) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO₂)]

The correction factor cf, which may be applied, is determined as follows:

cf = 0,825 + 0,0693 n_actual

where:

n_actual is the actual H/C ratio of the fuel used.

(c)

for vehicles with a positive-ignition engine fuelled with NG/biomethane:

FC_norm = (0,1336/0,654) · [(0,749 · HC) + (0,429 · CO) + (0,273 · CO₂)]

(d)

for vehicles with a positive-ignition engine fuelled with ethanol (E85):

FC = (0,1742/D) · [(0,574 · HC) + (0,429 · CO) + (0,273 · CO₂)]

(e)

for vehicles with a compression-ignition engine fuelled with diesel (B7):

FC = (0,1165/D) · [(0,859 · HC) + (0,429 · CO) + (0,273 · CO₂)]

(f)

for vehicles with a dedicated compression-ignition engine fuelled with ethanol (ED95):

FC = (0,186/D) · [(0,538 · HC) + (0,429 · CO) + (0,273 · CO₂)]

In these formulae:

FC

is the fuel consumption in litre per 100 km (in the case of petrol, ethanol, LPG, diesel or biodiesel) or in m³ per 100 km (in the case of natural gas)

HC

is the measured emission of hydrocarbons in g/km

CO

is the measured emission of carbon monoxide in g/km

CO₂

is the measured emission of carbon dioxide in g/km

D

is the density of the test fuel.

In the case of gaseous fuels this is the density at 288K (15 °C)’.

2.1.4. The reporting requirements in Section 3.4 of Annex XII to Regulation (EC) No 692/2008 shall be understood as referring to Appendix 4 to Annex I to this Regulation. U.K.
