Question

technician a says that catalytic converters are a post - combustion control device that perform a final cleanup of tailpipe emissions. technician b says that catalytic converters create heat as they burn off harmful gasses before leaving the exhaust system. who is correct?

a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

Explanation:

Catalytic converters are indeed post - combustion control devices that clean up tailpipe emissions. The chemical reactions in catalytic converters (such as the oxidation of carbon monoxide and unburned hydrocarbons) release heat as they convert harmful gases into less harmful substances before the exhaust leaves the system. So both Technician A and Technician B are correct.

Answer:

c. Both Technician A and Technician B
