Air-fuel ratio control system |
摘要 |
An air-fuel ratio control system for an internal combustion engine in which the air-fuel ratio of the engine is controlled by feedback using an air-fuel ratio sensor of a critical current type. When the air-fuel ratio is not controlled by such feedback, the voltage applied to the air-fuel ratio sensor is reduced or cut off to reduce physical deterioration thereof.
