# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 2.3.2.1

Extent: E+W+S+N.I.

The manufacturers may test the engine on a third fuel instead of G23 (fuel 3) if the λ-shift factor (Sλ) lies between 0,89 (that is the lower range of GR) and 1,19 (that is the upper range of G25), for example when fuel 3 is a market fuel. The results of this test may be used as a basis for the evaluation of the conformity of the production.
