Translation of "Moteur à compression variable " (French → English) :

Variable-speed engines of category IWP used for constant-speed operation shall additionally comply with Article 24(7) or Article 24(8), as applicable.

For variable speed CI engines test cycle E1 or E5 shall be applied or alternatively, above 130 kW, test cycle E3 may be applied .

(20a) For engines adapted for marine use, where the source engine is already type-approved in accordance with Directive 97/68/EC of the European Parliament and of the Council of 16 December 1997 on the approximation of the laws of the Member States relating to measures against the emission of gaseous and particulate pollutants from internal combustion engines to be installed in non-road mobile machinery or Directive 2005/55/EC of the European Parliament and of the Council of 28 September 2005 on the approximation of the laws of the Me ...[+++]mber States relating to the measures to be taken against the emission of gaseous and particulate pollutants from compression-ignition engines for use in vehicles, and the emission of gaseous pollutants from positive-ignition engines fuelled with natural gas or liquefied petroleum gas for use in vehicles, manufacturers should be able to rely on the proof of conformity issued by the original engine manufacturer where those adaptations have not altered exhaust emission characteristics.

(2) Originally, Directive 94/25/EC covered only recreational craft of a minimum hull length of 2,5 m and a maximum length of 24 m. Directive 2003/44/EC of the Council and the European Parliament of 16 June 2003 amending Directive 94/25/EC extended the scope of Directive 94/25/EC to include personal watercraft, and integrated environmental protection requirements into the amended Directive by adopting exhaust emission limits (CO, HC, NOx and particulates) and noise limits levels for propulsion engines, for both compression-ignition engines and spark-ignition engines.

(1) Directive 97/68/EC implements two stages of emission limit values for compression ignition engines and calls on the Commission to propose a further reduction in emission limits, taking into account the global availability of techniques for controlling air polluting emissions from compression ignition engines and the air quality situation.

'propulsion engine": any spark or compression ignition, internal combustion engine used for propulsion purposes, including 2-stroke and 4-stroke inboard, stern-drive with or without integral exhaust and outboard engines;
