Air-fuel ratio control system for catalytic engine exhaust emission control |
摘要 |
A closed loop fuel control system for an internal combustion engine in which the temperature of the exhaust gases passing by the oxygen sensor are regulated. The system utilizes a heated oxygen sensor in a slipstream of the exhaust gas and the temperature of the exhaust gas is controlled prior to its passing by the heated oxygen sensor for maximum efficiency of the catalytic converter.
