The MFI fuel injection system uses signals from the heated oxygen sensor to correct the fuel injector control modes installed in the intake manifold for each cylinder, and provides fine adjustment of the air-fuel ratio to reduce exhaust emissions.
This ensures the exit of exhaust gases of a certain composition, which can be further cleaned in a three-way catalytic converter.
Three Way Catalytic Converter Designed to Convert Three Harmful Substances (1) hydrocarbons (HC), (2) carbon monoxide (SO) And (3) nitrogen oxides (NOx) into safe substances.
