Having regard to Council Directive 70/220/EEC of 20 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 (3), as last amended by Directive 88/436/EEC (4), and in particular Article 5 thereof,

Having regard to Council Directive 72/245/EEC of 20 June 1972 on the approximation of the laws of the Member States relating to the suppression of radio interference produced by spark-ignition engines fitted to motor vehicles (5), and in particular Article 4 thereof,

Having regard to Council Directive 72/306/EEC of 2 August 1972 on the approximation of the laws of the Member States relating to the measures to be taken against the emission of pollutants from diesel engines for use in vehicles (6), and in particular Article 4 thereof,

Having regard to Council Directive 80/1268/EEC of 16 December 1980 on the approximation of the laws of the Member States relating to the fuel consumption of motor vehicles (7), and in particular Article 3 thereof,

Whereas Council Directive 88/76/EEC (10) amending Directive 70/220/EEC introduces requirements relating to the use of unleaded petrol; whereas the adaptation of existing engines to this petrol necessitates in many cases technical modifications which are relevant to the compliance with the abovementioned Directives; whereas it appears appropriate to facilitate the administrative handling of the resulting amendments of the type-approval of the vehicles concerned in the interests of rapidly increasing use of unleaded petrol; whereas it appears also necessary to render more precise the specifications of Directive 88/76/EEC preventing vehicles equipped with emission control devices which would be adversely affected by leaded petrol, to be refuelled with such petrol; whereas it appears equally appropriate to introduce the new reference fuel for diesel engines specified in this Directive into Directive 72/306/EEC relating to the smoke emissions of such engines; whereas it appears advisable to align on this occasion the technical

provisions of Directive 80/1269/EEC relating to engine power to those of the corresponding Regulation of the Economic Commission for Europe;

Whereas it is desirable to introduce the amendments contained in the present Directive as soon as possible into the national laws concerned as they are particularly needed during the transitional period where vehicles conceived for the use of leaded petrol and vehicles requiring unleaded petrol will co-exist;

Whereas the provisions of this Directive are in accordance with the opinion of the Committee for the Adaptation to Technical Progress of the Directives on Motor Vehicles,

HAS ADOPTED THIS DIRECTIVE:

1. 8 is replaced by:

1.2 // '8. // EXTENSION OF EEC TYPE APPROVAL // 8.1. // Vehicle types modified to run on unleaded petrol // 8.1.1. // Subject to the approval of the authority granting type approval, approval of a vehicle type modified and/or adjusted solely for the purpose of making it capable of running on unleaded petrol, as specified in Directive 85/210/EEC, shall be extended under the following alternative conditions: // 8.1.1.1. // The manufacturer shall certify that the engine power of the modified vehicle shall remain within the limits for conformity of production, as specified in 9.2 as obtained with the original, unmodified, type approved vehicle. In this case the extension shall confirm the power of the original type approval, or // 8.1.1.2. // The manufacturer shall declare a revised engine power figure which is less than that obtained with the original, unmodified type approved vehicle. In this case the extension shall specify the newly declared figures as applicable to the modified vehicle type. // 8.2. // Vehicle types modified for any other purpose // // Any other modification of the engine with regard to the characteristics listed in Appendix 1 or Apendix 2 to this Annex shall be reported to the competent authority. That authority may then either: // 8.2.1. // consider that the modifications made are not likely to have any substantial effect on the power of the engine, or // 8.2.2. // request a further determination of engine power through the carrying-out of such tests as are deemed necessary.'

2. 9 is replaced by:

1.2 // '9. // TOLERANCES FOR MEASURING THE NET POWER // 9.1. // The net power indicated by the manufacturer for the type of engine shall be accepted if it does not differ by more than ± 2 % for maximum power and more than ± 4 % at, the other measurement points on the curve with a tolerance of ± 1,5 % for engine speed, from the values measured by the technical service on the engine submitted for testing. // 9.2 // During the tests to verify conformity of production the power shall be measured at two engine speeds S1 and S2 corresponding respectively to the measurement points of maximum power and maximum torque accepted for type approval. At these two engine speeds, which are subject to a tolerance of + 5 %, the net power measured at at least one point within the ranges S1 ± 5 % and S2 ± 5 % shall not differ by more than ± 5 % from the approval figure'.
