Division 7.2.3.5 Non-compliance of gas and dual-fuel enginesF1

In the case of a dispute caused by the non-compliance of gas fuelled engines, including dual-fuel engines, when using a market fuel, the tests shall be performed with each reference fuel on which the parent engine has been tested, and with the possible additional third fuel as referred to in points 1.1.4.1 and 1.2.1.1 on which the parent engine may have been tested. Where applicable, the result shall be converted by a calculation applying the relevant factors ‘r’, ‘r _a ’ or ‘r _b ’ as described in points 1.1.5, 1.1.6.1 and 1.2.1.2. If r, ra or rb are less than 1, no correction shall take place. The measured results and, where applicable, the calculated results shall demonstrate that the engine meets the limit values with all relevant fuels (for example, fuels 1, 2 and fuel 3 in the case of natural gas engines and fuels A and B in the case of LPG engines).
