COMMISSION 
Proposal for a Council Directive on the approximation of the laws of the Member States 
relating to the measures to be taken against the emission of gaseous pollutants from diesel 
engines for use in vehicles 
COM(86) 273 final 
(Submitted by the Commission to the Council on 23 June 1986) 
(86/C 193/03) 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European 
Economic Community, and in particular Article 100 
thereof, 
Having regard to the proposal from the Commission, 
Having regard to the opinion of the European 
Parliament, 
Having regard to the opinion of the Economic and 
Social Committee, 
Whereas the technical requirements which motor vehicles 
must satisfy pursuant to national laws relate, inter alia, to 
the emission of gaseous pollutants from diesel engines 
for use in vehicles; 
Whereas those requirements differ from one Member 
State to another; whereas these differences could restrict 
the free movement of the products in question; whereas 
it is therefore necessary that all the Member States adopt 
the same requirements either in addition to or in place of 
their existing rules, in order, in particular, to allow the 
implementation of the EEC type-approval procedure 
which was the subject of 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 (*), as last amended by 
Directive 80/1267/EEC (2); 
(») OJ No L 42, 23. 2. 1970, p. 1. 
O OJ No L 375, 31. 12. 1980, p. 34. Whereas it is desirable to follow the technical 
requirements adopted by the United Nations Economic 
Commission for Europe (ECE) in its Regulation No 49 
(Uniform provisions concerning the approval of diesel 
engines with regard to the emission of gaseous 
pollutants), which is annexed to the Agreement of 20 
March 1958 concerning the adoption of uniform 
conditions of approval and reciprocal recognition of 
approval for motor vehicle equipment and parts (3), 
HAS ADOPTED THIS DIRECTIVE: 
Article 1 
For the purposes of this Directive, Vehicle' means any 
vehicle propelled by a diesel engine, intended for use on 
the road, with or without bodywork, having at least four 
wheels and a maximum design speed exceeding 25 km/h, 
with the exception of vehicles of category Mj as defined 
in point 0.4 of Annex I to Directive 70/156/EEC, having 
a total mass not exceeding 3,5 tonnes, and vehicles 
which run on rails, agricultural tractors and machines 
and public works vehicles. 
Article 2 
No Member State may refuse to grant EEC type-
approval or national type-approval of: 
— a vehicle type in respect of its diesel engine, or 
— a type of diesel engine,

on grounds relating to the gaseous pollutants emitted by 
such an engine if: 
— the vehicle type is propelled by a diesel engine for 
which type-approval of a separate technical unit 
within the meaning of Article 9a of Directive 
70/156/EEC has been granted in accordance with 
the requirements as laid down in the Annexes to this 
Directive, 
— such a diesel engine regarded as a separate technical 
unit within the meaning of Article 9a of Directive 
70/156/EEC satisfies the relevant requirements as 
laid down in the Annexes to this Directive.

Member State shall decide whether fresh tests should be 
carried out on the modified engine and a fresh report 
drawn up. Where the tests reveal failure to comply with 
this Directive, the modification shall not be approved. 
2. The Member State which has granted type-
approval of a vehicle type in respect of its diesel engine 
shall take the necessary measures to ensure that it is 
informed of any modification of such vehicle type as 
regards the engine installed. The competent authorities 
of that Member State shall decide whether after a 
modification measures in application of Directive 
70/156/EEC, especially of Article 4 or of Article 6 
thereof, must be taken. 
Article 4 
The amendments necessary for adapting the Annexes so 
as to take account of technical progress shall be adopted 
in accordance with the procedure laid down in Article 5. Article 5 
Where the procedure laid down in this Article is 
followed, the Commission shall decide after consulting 
the Committee set up by Directive 70/156/EEC, herein­
after referred to as 'the Committee'. The Committee 
shall deliberate on requests for its opinion formulated by 
the Commission. The Commission, in seeking the 
opinion of the Committee, may fix a time limit within 
which that opinion must be given. The deliberations of 
the Committee shall not be followed by a vote. 
However, each member of the Committee may require 
that his opinion be entered in the minutes.

ANNEX III 
TEST PROCEDURE 
INTRODUCTION 
This Annex describes the method of determining emissions of gaseous pollutants from the 
engines to be tested. 
The test shall be carried out with the engine mounted on a test bench and connected to a 
dynamometer. 
MEASUREMENT PRINCIPLE 
The gaseous emissions from the exhaust of the engine include hydrocarbons, carbon 
monoxide and oxides of nitrogen. During a prescribed sequence of warmed-up-engine 
operating conditions the amounts of the above gases in the exhaust shall be examined 
continuously. The prescribed sequence of operations consist of a number of speed and power 
modes which span the typical operating range of diesel engines. During each mode the 
concentration of each pollutant, exhaust flow and power output shall be determined and the 
measured values weighted and used to calculate the grams of each pollutant emitted per 
kilowatt hour, as described in this Annex. 
EQUIPMENT 
Dynamometer and engine equipment 
The following equipment shall be used for emission tests of engines on engine dynamo­
meters : 
an engine dynamometer with adequate characteristics to perform the test cycle described in 
paragraph 4.1 of this Annex; 1.

3.1.2. measuring instruments for speed, torque, fuel consumption, air consumption, temperature of 
coolant and lubricant, exhaust gas pressure and section flow resistance, exhaust gas 
temperature, air inlet temperature, atmospheric pressure, fuel temperature and humidity. The 
accuracy of these instruments shall satisfy the EEC method of measuring the power of the 
internal combustion engines of road vehicles; 
3.1.3. an engine cooling system with sufficient capacity to maintain the engine at normal operating 
temperatures for the duration of the prescribed engine tests; 
3.1.4. a non-insulated and uncooled exhaust system extending at least 0,5 m past the point where 
the exhaust probe is located, and presenting an exhaust backpressure within ± 650 Pa 
(±5 mm Hg) of the upper limit at the maximum rated power, as established by the engine 
manufacturer's sale and service literature for vehicle application; 
3.1.5. an engine air inlet system presenting an air inlet restriction within ± 300 Pa (225 mm H2O) 
of the upper limit for the engine operating condition which results in maximum air flow, as 
established by the engine manufacturer for an air cleaner, for the engine being tested. When 
an engine is tested for exhaust emissions, the complete engine shall be tested with all 
standard accessories which might reasonably be expected to influence emissions to the 
atmosphere installed and functioning. 
3.2. Analytical and sampling equipment 
The system shall comprise one FID analyzer for the measurement of the unburned hydro­
carbons (HC), and NDIR analyzer for measurement of carbon monoxide (CO) and a CLA 
or NDUVR analyzer for measurement of oxides of nitrogen (NOx). Due to the heavy 
hydrocarbons present in the diesel exhaust, the FID system shall be heated and maintained at 
a temperature between 423 and 473 K (150 and 200 °C). 
The accuracy of the analyzers shall be ± 2,5 % of full-scale deflection or better. The scale 
of measurement of the analyzers shall be selected appropriately in relation to the values 
measured. 
The following span and zero gases may be used:

4.2. Measurement of exhaust gas flow 
For calculation of the emission it is necessary to know the exhaust gas flow (see paragraph 
4.8.1.1 below). For determination of exhaust flow either of the following methods may be

imately 50 % and 90 % of each range used. The concentration of the standards shall be 
obtained to within ± 2,5 % accuracy. 
4.3.1.7. The calibration results shall be compared with previous data. Any significant change may 
reflect a system fault which shall be located, corrected and recalibrated. The best fitting 
calibration curve shall be selected, taking into account the accuracy of the calibration of 
standard gases. 
4.3.2. Pre-test checks 
A minimum of two hours shall be allowed for warming up the infrared NDIR analyzers, but

The figures quoted show the total evaporated quantities (% recovered 4- % loss). 
This fuel may be based on straight run and cracked distillates; desulphurization is 
allowed. It must not contain any metallic additives. 
The values quoted in the specification are 'true values'. In establishment of their limit 
values the terms of ASTM D 3244 Defining a Basis for Petroleum Product Quality 
Disputes have been applied and in fixing a maximum value, a minimum difference of 
2 R above zero has been taken into account; in fixing a maximum and minimum 
value, the minimum difference is 4 R (R = reproducibility). 
Notwithstanding this measure, which is necessary for statistical reasons, the manu­
facturer of a fuel should nevertheless aim at a zero value where the stipulated 
maximum value is 2 R and at the mean value in the case of quotations of maximum 
and minimum limits. 
Should it be necessary to clarify the question as to whether a fuel meets the 
requirements of the specification, the terms of ASTM D 3244 should be applied. 
If it is required to calculate the thermal efficiency of an engine or vehicle, the 
calorific value of the fuel can be calculated from: 
Specific energy (calorific value) (net) MJ/kg 
(46,423-8,792d2 + 3,170d) I 1 — (x + y + s) I + 9,420s — 2,449x where: 
d is the density at 15 ° C, 
x is the proportion by mass of water (°/o divided by 100), 
y is the proportion by mass of ash (°/o divided by 100), 
s is the proportion by mass of sulphur (°/o divided by 100).
