15
if CO+CO2 is lower than 15, otherwise CO corr = CO
K) Compare following data with the corresponding ones declared by the car
manufacturer, or with expected values:
- CO
- CO2
- HC
- O2
- Lambda
Lambda is a parameter computed as follows:
Lambda = Num / Den
where:
Num:
21 x [ [CO2] + ([CO]/2) + [O2] + ((HCV/4) x 3,5 / (3,5 + [CO] / [CO2]) - 0.00877) x ([CO2] + [CO]) ]
Den:
[21+0.5628 x (([CO]/[CO2]) / (3,5+([CO] / [CO2]))]x[ 1+HCV/4 - 0,01754/2] x [CO2]+[CO]+[HC] x6 x10
-4
]
where HCV = 1.85 for engine supplied with Gasoline
= 2.57 for engine supplied with GPL
= 4 for engine supplied with Methane
With [CO], [CO2] e [O2] = % in vol. and HC = ppm in vol.
If out of range data are measured, proceed with proper repairs and adjustments on
the motorcar.
L) After this work, print a report (*) of repairs and adjustments done.
