Eclipse FWD L4-1997cc 2.0L DOHC MFI (1997)
Catalytic Converter: Description and Operation
DESCRIPTION
The three-way catalytic converter, together with the closed loop air-fuel ratio control (based on the oxygen sensor signal) oxidizes carbon
monoxides (CO) and hydrocarbons (HO), and reduces nitrogen oxides (NOx).
When the mixture is controlled at stoichiometric air-fuel ratio, the three-way catalytic converter provides the highest purification against CO, HO,
and NOx.
