Use the LPG Composition drop-down menu to specify the appropriate
ratio of Butane (C
4
H
10
) to Propane (C
3
H
8
) in the LPG fuel used by the
test vehicle.
The available range is from 100% Butane to 100% Propane in 10%
increments. This information is required for the determination of the
ratio of Hydrogen to Carbon present in the fuel, which information is,
in turn, used for the accurate determination of Lambda.
Note:
The composition of LPG fuel may vary from country to country. If the
composition of the LPG fuel is not known, set the Butane/Propane ratio
to 50%/50%. If the composition is known (e.g. LPG used in the United
Kingdom has a composition of 0% Butane/100% Propane), this ratio
should be selected.
Note:
The section marked with the RED outline is not accessible by an end
