The three way catalytic converter cannot control which one of the following?
Option (A)
HC emission
Option (B)
CO emission
NOx emission
PM emission
Correct Option:
Question Solution:
Catalytic converter contain two separate elements one for the treatment of NOx and other for HC/CO emission. The exhaust gas first come in contact with reduction bed because to convert NOx to N2 and O2 it requires bed and oxygen for reduction comes from the reduction bed.
So the catalytic converter does not control PM emission.
