Abstract

A method includes i) identifying a period of operation corresponding to a fuel supply requirement; ii) determining at least one ambient air condition in which the machine will operate during the period; iii) determining a duration of time in which, whilst in the ambient air condition, it is required to achieve a predetermined vapour trail characteristic; iv) determining a resultant fuel composition for use by the machine in the ambient air condition to achieve the characteristic, where the resultant fuel composition includes at least one of the first and second fuel compositions; v) determining the ratio of at least the first and second fuel compositions required for sufficient resultant fuel composition for the duration of time determined in step iii); and vi) producing a first signal indicative of the ratio of at least the first and second fuel compositions required for the duration of time determined in step iii).

A method of supplying at least one of a first fuel composition and second fuel composition for use in a machine to achieve a fuel supply requirement, where the first fuel composition is different to the second fuel composition, the method comprising the steps of:

i) identifying a period of operation corresponding to the fuel supply requirement;
ii) determining at least one ambient air condition in which the machine will operate during the period of operation;
iii) determining a duration of time in which, whilst in the ambient air condition, it is required to achieve a predetermined vapour trail characteristic, where the said duration may be equal to or less than the period of operation;
iv) determining a resultant fuel composition for use by the machine in the ambient air condition to achieve the predetermined vapour trail characteristic, where the resultant fuel composition comprises at least one of the first fuel composition and the second fuel composition;
v) determining the ratio of at least the first fuel composition and second fuel composition required for sufficient resultant fuel composition for the duration of time determined in step iii);
and
vi) producing a first signal indicative of the ratio of at least the first and second fuel compositions required for the duration of time determined in step iii).
