1.REQUIREMENTS ON FUEL RANGEU.K.
[1.3. Requirements on fuel-specific type-approval U.K.
1.3.1. A fuel specific type-approval may be granted for LNG fuelled engines, including dual-fuel engines, labelled with an approval mark containing the letters ‘LNG 20 ’ in accordance with point 3.1 of this Annex. U.K.
1.3.2. The manufacturer can only apply for a fuel specific type-approval in the case of the engine being calibrated for a specific LNG gas composition resulting in a λ-shift factor not differing by more than 3 per cent from the λ-shift factor of the G 20 fuel specified in Annex IX, and the ethane content of which does not exceed 1.5 per cent. U.K.
1.3.3. In the case of a dual-fuel engine family where the engines are calibrated for a specific LNG gas composition resulting in a λ-shift factor not differing by more than 3 per cent from the λ-shift factor of the G 20 fuel specified in Annex IX, and the ethane content of which does not exceed 1.5 per cent, the parent engine shall only be tested on the G 20 reference gas fuel, as specified in Annex IX.] U.K.
