of Lambda when certain components of the exhaust are measured.
B.1 OXYGEN BALANCE FORMULA
For Lambda calculation, based upon measurements of CO, CO2, HC and O2, the following formula is stan-
dardized: Displayed on the analyzer as LAMBDA (O)
l
= CO2 + (CO/2) + O2 + [HCV/4 × {3.5 / (3.5 + CO/CO2)} – OCV/2] × (CO2 + CO)
(1 + HCV/4 - OCV/2) × {(CO2 + CO) + (K1 × HC)}
Where:
CO =
Carbon monoxide % volume measured.
CO
2
=
Carbon dioxide % volume measured.
HC =
Hydrocarbon ppm volume measured.
O
2
=
Oxygen % volume measured.
K
1
=
Conversion factor for HC is expressed in ppm vol n-hexane (C6H14) equivalent. Its
value in this formula is 6.10-4
H
CV
=
Atomic ratio hydrogen to carbon in the fuel. Nominal value is 1.7261
O
CV
=
Atomic ratio oxygen to carbon in the fuel. Nominal value is 0.0176
