March 1970 on the approximation of the laws of the
Member States relating to measures to be taken against air
pollution by emissions from motor vehicles (1), as last
amended by Directive 96/69/EC of the European Parlia-
ment and of the Council (2),

Whereas Article 13(2) of Directive 70/156/EEC lays down
that the procedure of Article 13 shall also apply to the
introduction of provisions on the type-approval of sep-
arate technical units into the separate directives;

Whereas to provide a harmonised basis to guarantee that
replacement catalytic converters, intended to be fitted on
vehicles of category M1 and N1 not equipped with on-
board diagnostic systems, are of sufficient quality, it is
appropriate to introduce into Directive 70/220/EEC new
technical

replacement catalytic converters as a separate technical
unit; whereas these technical requirements are in accord-
ance with the technical requirements adopted by the
United Nations Economic Commission for Europe in its
Regulation No 103 relating to the approval of replace-
ment catalytic converters for power-driven vehicles (5);

INTRODUCTION

This Annex describes the special requirements that apply in the case of an approval of a vehicle

In the case of LPG and natural gas there is on the market a large variation in fuel composition,
requiring the fuelling system to adapt its fuelling rates to these compositions. To demonstrate this
capability, the vehicle has to be tested in the test type I on two extreme reference fuels and
demonstrate the self-adaptability of the fuelling system. Whenever the self adaptability of a
fuelling system has been demonstrated on a vehicle, such a vehicle may be considered as a parent
of a family. Vehicles that comply with the requirements of members of that family, if fitted with
the same fuelling system, need to be tested on only one fuel.

2.

DEFINITIONS

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.

2.2.

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

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 manufac-
turer 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.

3.

GRANTING OF AN EC TYPE-APPROVAL

EC type-approval is granted subject to the following requirements:

3.1.

Exhaust emissions approval of a parent vehicle:

The parent vehicle should 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.

3.1.1. The parent vehicle(s) shall be tested in the test type I on the two extreme reference fuels of Annex

IXa.

L 286/44

EN

Official Journal of the European Communities

23. 10. 98

3.1.1.1. If the transition from one fuel to another is in practice aided through the use of a switch, this
switch shall not be used during type approval. In such a case on the manufacturer’s request and
with the agreement of the technical service the pre-conditioning cycle referred to in point 5.3.1 of
Annex III may be extended.

3.1.2. The vehicle(s) is (are) considered to conform if, with both reference fuels, the vehicle complies

with the emission limits.

3.1.3. The ratio of emission results “r” should be determined for each pollutant as follows:

r =

{emission result on one reference fuelﬁ
{emission result on the other reference fuelﬁ

3.2.

Exhaust emissions approval of a member of the family:

For a member of the family a test of type I shall be performed with one reference fuel. This
reference fuel may be either reference fuel. The vehicle is considered to comply if the following
requirements are met:

3.2.1. The vehicle complies with the definition of a family member as defined under point 2.2.

3.2.2. The test results for each pollutant will be multiplied with its factor “r” (see point 3.1.3), if r is
greater than 1,0. If r is smaller than 1,0, its value will be taken as 1. The results of these
multiplications shall be taken as the final emission result. On the manufacturer’s request the test
type I may be performed on reference fuel 2 or on both reference fuels, so that no correction is
needed.

3.2.3. The vehicle shall comply with the emission limits valid for the relevant category for both

measured and calculated emissions.

4.

GENERAL CONDITIONS

4.1.

Tests for conformity of production may be performed with a commercial fuel of which the C3/C4
ratio lies between those of the reference fuels in the case of LPG, or of which the Wobbe index
lies between those of the extreme reference fuels in the case of NG. In that case a fuel analysis
needs to be present.'
