Consider the following statements Exhaust emissions of carbon monoxide from spark ignition engine are.
1. mainly fuel-air mixture strength dependent
2. in the range of zero to 10%
3. measured with the help of an instrument working on the principle of non-dispersive infra-red analysis
4. controlled by the use of a two way catalytic convertor
Which of the statements given above are correct?
Option (A)
1 and 4
Option (B)
2 and 3
1 and 3
1, 2, 3 and 4
Correct Option:
Question Solution:
NDIR accurately measure CO, CO2 and UBHC, CO in oxidized in 2-way catalytic convertor at platinum palladium metal matrix honey comb.
Formation of CO is strength dependent (F/A ratio)
