Council Directive of 20 March 1970 on the approximation of the laws of the Member States on measures to be taken against air pollution by emissions from motor vehicles (70/220/EEC) (repealed) (c. 220)

[F1 ANNEX XII U.K. EC TYPE-APPROVAL FOR A VEHICLE FUELLED BY LPG OR NATURAL GAS WITH REGARD TO ITS EMISSIONS

Textual Amendments

F1 Inserted by Commission Directive 98/77/EC of 2 October 1998 adapting to technical progress Council Directive 70/220/EEC on the approximation of the laws of the Member States relating to measures to be taken against air pollution by emissions from motor vehicles (Text with EEA relevance).

2. DEFINITIONS U.K.

For the purpose of this Annex:

2.1. 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.

2.2. A member of the family is a vehicle that shares the following essential characteristics with its parent(s): U.K.

2.2.1.

(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.

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.

(d)

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

(e)

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).

(f)

This gas fuelling system is controlled by an ECU of the same type and technical specification, containing the same software principles and control strategy.

2.2.2. With regard to requirement (c): 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.] U.K.
