COMMISSION DIRECTIVE 1999/100/EC

of 15 December 1999

adapting to technical progress Council Directive 80/1268/EEC relating to the carbon dioxide
emissions and the fuel consumption of motor vehicles

(Text with EEA relevance)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

(4)

The measures provided for in this Directive are in
the Committee for
accordance with the opinion of
Adaptation to Technical
by
established
Directive 70/156/EEC,

Progress

Having regard to the Treaty establishing the European
Community,

Having regard to Council Directive 70/156/EEC of 6 February
1970 on the approximation of the laws of the Member States
relating to the type-approval of motor vehicles and their
trailers (1), as last amended by Directive 98/91/EC of the Euro-
pean Parliament and of the Council (2), and in particular Article
13(2) thereof,

Having regard to Council Directive 80/1268/EEC of 16
December 1980 relating to the carbon dioxide emissions and
the fuel consumption of motor vehicles (3), as last amended by
Commission Directive 93/116/EC (4), and in particular Article 3
thereof,

Whereas:

(1)

(2)

Directive 80/1268/EEC is one of the separate Directives
of the EC type-approval procedure which was estab-
lished by Directive 70/156/EEC. Consequently,
the
provisions laid down in Directive 70/156/EEC relating to
vehicle systems, components and separate technical
units apply to this Directive.

In Directive 98/69/EC of the European Parliament and
Council of 13 October 1998 relating to measures to be
taken against air pollution from motor vehicles and
amending Council Directive 70/220/EEC (5), the type I
test cycle for emission measurement was amended by
abolishing the initial 40 seconds of engine idle time. It is
necessary to align the test cycle for the measurement of
CO2 emissions and fuel consumption in Directive 80/
1268/EEC accordingly.

(3) With a view to the monitoring of CO2 emissions in the
framework of the Community strategy to reduce CO2
emissions of passenger cars, it is appropriate to intro-
duce into Directive 80/1268/EEC new technical require-
ments regarding the measurement of CO
emissions and
fuel consumption for the EC type-approval of gas-fuelled
vehicles (LPG and NG). In this respect, it is appropriate
to follow the technical requirements adopted by the
United Nations Economic Commission for Europe in its
Regulation No 101 (6).

4.4.2.

LPG and NG-fuelled vehicles

For LPG and NG, that fuel must be used which is chosen by the manufacturer for the measurement of the net
power in accordance with Annex I to Directive 80/1269/EEC. The chosen fuel shall be specified in the
communication document as defined in Annex II.

4.4.3.

For the purpose of calculation mentioned in 4.3, the following fuel characteristics will be used:

(a) density: measured on the test fuel according to ISO 3675 or an equivalent method; for petrol and diesel

8. Item 7.2 is replaced by the following:

‘7.2.

The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG or diesel) or in m3 per
100 km (in the case of NG),

is calculated by means of the following formulae: (**)

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

)]
FC = (0,1154/D) × [(0,866 × THC) × (0,429 × CO) × (0,273 × (CO2

(b) for vehicles with a positive ignition engine fuelled with LPG:

FCnorm

= (0,1212/0,538) × [(0,825 × THC)+(0,429 × CO)+(0,273 × CO

)]
2

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:

FCnorm

= (0,1212/0,538) × cf × [(0,825 × THC)+(0,429 × CO)+(0,273 × C0

)]
2

The correction factor cf, which may be applied,

is determined as follows:

cf = 0,825+0,0693 × nactual

where:

nactual

=the actual H/C ratio of the fuel used

(c) for vehicles with a positive ignition engine fuelled with NG:

FCnorm

= (0,1336/0,654) × [(0,749 × THC)+(0,429 × CO)+(0,273 × CO

)]
2

(d) for vehicles with a compression ignition engine:

FC = (0,1155/D) × [(0,866 × THC)+(0,429 × CO)+(0,273 × C02)]

In these formulae:

FC

= the fuel consumption in litre per 100 km (in the case of petrol, LPG or diesel) or in m3 per

100 km (in the case of NG)

THC

= the measured emission of total hydrocarbons in g/km

CO

CO
2

D

= the measured emission of carbon monoxide in g/km

= the measured emission of carbon dioxide in g/km

= the density of the test fuel at 15 °C.

(**) Repeat for petrol and gaseous fuel in the case of a vehicle that can run either on petrol or on a

gaseous fuel. Vehicles that can be fuelled with both petrol and a gaseous fuel, but where the petrol
system is fitted for emergency purposes or starting only and of which the petrol tank cannot contain
more than 15 litres of petrol will be regarded for the test as vehicles which can only run a gaseous
fuel.’
