1. ADDITIONAL REQUIREMENTS FOR GRANTING OF EC TYPE-APPROVAL U.K.

[F1 1.1. Additional requirements for mono fuel gas vehicles, bi-fuel gas vehicles and flex fuel H2NG vehicles.] U.K.

1.1.1.

For the purposes of section 1.1 the following definitions shall apply: U.K.

[F1 1.1.1.1. A family means a group of vehicle types fuelled by LPG, NG/biomethane, H2NG, identified by a parent vehicle.] U.K.

1.1.1.2. A parent vehicle means a vehicle that is selected to act as the vehicle on which the self adaptability of a fuelling system is going to be demonstrated, and to which the members of a family refer. It is possible to have more than one parent vehicle in a family. U.K.

1.1.1.3. A member of the family means a vehicle that shares the following essential characteristics with its parent: U.K.

(a)

It is produced by the same vehicle manufacturer;

(b)

It is subject to the same emission limits;

(c)

If the gas fuelling system has a central metering for the whole engine, it has a certified power output between 0,7 and 1,15 times that of the engine of the parent vehicle;

(d)

If the gas fuelling system has an individual metering per cylinder, it has a certified power output per cylinder between 0,7 and 1,15 times that of the engine of the parent vehicle;

(e)

If fitted with a catalyst system, it has the same type of catalyst i.e. three-way, oxidation, de NO_x;

(f)

It has a gas fuelling system (including the pressure regulator) from the same system manufacturer and of the same type: induction, vapour injection (single point, multipoint), liquid injection (single point, multipoint);

(g)

This gas fuelling system is controlled by an ECU of the same type and technical specification, containing the same software principles and control strategy. The vehicle may have a second ECU compared to the parent vehicle, provided that the ECU is only used to control the injectors, additional shut-off valves and the data acquisition from additional sensors.

With regard to the requirements referred to in point (c) and (d), in the case where a demonstration shows two gas fuelled vehicles could be members of the same family with the exception of their certified power output, respectively P₁ and P₂ (P₁ < P₂), and both are tested as if they were parent vehicles, the family relation will be considered valid for any vehicle with a certified power output between 0,7 × P₁ and 1,15 × P₂.

[F1 1.1.2.

In case of vehicles fuelled by LPG, NG/biomethane, H2NG, EC type-approval is granted subject to the following requirements:] U.K.

1.1.2.1. For the type-approval of a parent vehicle, the parent vehicle shall demonstrate its capability to adapt to any fuel composition that may occur across the market. In the case of LPG there are variations in C3/C4 composition. In the case of natural gas there are generally two types of fuel, high calorific fuel (H-gas) and low calorific fuel (L-gas), but with a significant spread within both ranges; they differ significantly in Wobbe index. These variations are reflected in the reference fuels. U.K.

[F2 In the case of a flex fuel H2NG vehicle, the composition range may vary from 0 % hydrogen to a maximum percentage of hydrogen within the mixture, which shall be specified by the manufacturer. The parent vehicle shall demonstrate its capability to adapt to any percentage, within the range specified by the manufacturer. It shall also demonstrate its capability to adapt to any NG/biomethane composition that may occur across the market, regardless of the percentage of hydrogen in the mixture.]

F2 Inserted by Commission Regulation (EU) No 630/2012 of 12 July 2012 amending Regulation (EC) No 692/2008, as regards type-approval requirements for motor vehicles fuelled by hydrogen and mixtures of hydrogen and natural gas with respect to emissions, and the inclusion of specific information regarding vehicles fitted with an electric power train in the information document for the purpose of EC type-approval (Text with EEA relevance).

[F1 1.1.2.2. In the case of vehicles fuelled by LPG, NG/biomethane, the parent vehicle shall be tested in the type 1 test on the two extreme gas reference fuels set out in Annex IX. In the case of NG/biomethane, if the transition from one gas fuel to the other gas fuel is, in practice, aided through the use of a switch, this switch shall not be used during type-approval. U.K.

In the case of flex fuel H2NG vehicles, the parent vehicle shall be tested in the type 1 test with the following fuel compositions:

• 100 % H-gas.

• 100 % L-gas.

• The mixture of H-gas and the maximum percentage of hydrogen specified by the manufacturer.

• The mixture of L-gas and the maximum percentage of hydrogen specified by the manufacturer.

1.1.2.3. The vehicle is considered to conform if, under the tests and reference fuels mentioned in point 1.1.2.2, the vehicle complies with the emission limits. U.K.

1.1.2.4. In the case of vehicles fuelled by LPG or NG/biomethane, the ratio of emission results ‘ r ’ shall be determined for each pollutant as follows: U.K.

Type of fuel	Reference fuels	Calculation of ‘r’
LPG	fuel A
	fuel B
NG/Biomethane	fuel G20
	fuel G25]

[F2 1.1.2.5. In the case of flex fuel H2NG vehicles, two ratios of emission results ‘r ₁ ’ and ‘r ₂ ’, shall be determined for each pollutant as follows: U.K.

Type of fuel	Reference fuels	Calculation of ‘r’
NG/biomethane	fuel G20
	fuel G25
H2NG	Mixture of hydrogen and G20 with the maximum percentage of hydrogen specified by the manufacturer
	Mixture of hydrogen and G25 with the maximum percentage of hydrogen specified by the manufacturer]

1.1.3. [F1 For the type-approval of a mono- fuel gas vehicle and bi-fuel gas vehicles operating in gas mode, fuelled by LPG or NG/biomethane, as a member of the family, a type 1 test shall be performed with one gas reference fuel. This reference fuel may be either of the gas reference fuels. The vehicle is considered to comply if the following requirements are met:] U.K.

(a)

the vehicle complies with the definition of a family member as defined in section 1.1.1.3;

(b)

if the test fuel is the reference fuel A for LPG or G20 for NG/Biomethane, the emission result for each pollutant shall be multiplied by the relevant factor ‘r’ calculated in section 1.1.2.4 if r > 1; if r < 1, no correction is needed;

(c)

if the test fuel is the reference fuel B for LPG or G25 for NG/Biomethane, the emission result for each pollutant shall be divided by the relevant factor ‘r’ calculated in section 1.1.2.4 if r < 1; if r > 1, no correction is needed;

(d)

on the manufacturer’s request the type 1 test may be performed on both reference fuels, so that no correction is needed;

(e)

the vehicle shall comply with the emission limits valid for the relevant category for both measured and calculated emissions;

(f)

if repeated tests are made on the same engine the results on reference fuel G20, or A, and those on reference fuel G25, or B, shall first be averaged; the ‘r’ factor shall then be calculated from these averaged results;

(g)

during the type 1 test the vehicle shall only use petrol for a maximum of 60 seconds when operating in gas mode.

[F2 1.1.4. For the type-approval of a flex fuel H2NG vehicle as a member of a family, two type 1 tests shall be performed, the first test with 100 % of either G20 or G25, and the second test with the mixture of hydrogen and the same NG/biomethane fuel used during the first test, with the maximum hydrogen percentage specified by the manufacturer. U.K.

The vehicle tested in accordance with the first paragraph shall be considered as complying if, in addition to requirements set out in points (a), (e) and (g) of point 1.1.3., the following requirements are met:

(a)

if the NG/biomethane fuel is the reference fuel G20, the emission result for each pollutant shall be multiplied by the relevant factors (r ₁ for the first test and r ₂ for the second test), calculated in section 1.1.2.5, if the relevant factor > 1; if the correspondent relevant factor < 1, no correction is needed;

(b)

if the NG/biomethane fuel is the reference fuel G25, the emission result for each pollutant shall be divided by the correspondent relevant factor (r ₁ for the first test and r ₂ for the second test) calculated in accordance with point 1.1.2.5, if the correspondent relevant factor < 1; if the correspondent relevant factor > 1, no correction is needed;

(c)

on the manufacturer's request the type 1 test must be performed with the four possible combinations of reference fuels, according to section 1.1.2.5, so that no correction is needed;

(d)

if repeated tests are made on the same engine the results on reference fuel G20, or H2G20, and those on reference fuel G25, or H2G25 with the maximum hydrogen percentage specified by the manufacturer, shall first be averaged; the ‘r ₁ ’ and ‘r ₂ ’ factors shall then be calculated from these averaged results.]
