Division 6.6.1

If the composition of the fuel used for the test differs from the composition that is assumed for the calculation of the normalised consumption, on the manufacturer's request a correction factor cf may be applied, using the following equation:

{FC}_{norm} = (\frac{0,1212}{0,538}) \times cf \times [(0,825 \times HC) + (0,429 \times CO) + (0,273 \times {CO}_{2})]

The correction factor, cf, which may be applied, is determined using the following equation:

cf = 0,825 + 0,0693 \times n_{actual}

where:

n_actual is the actual H/C ratio of the fuel used.
