Abstract

The present invention provides a voltage detecting regulator with O₂ sensor, and this regulating device uses a voltage detecting unit and a regulating unit. The voltage detecting unit detects the feedback voltage of the O₂ Sensor and adjusts the bias voltage by manual or automatic control. The abnormality of the feedback voltage of the O₂ Sensor can be restored by the regulating unit of the present invention to maintain the normal state of air-fuel ratio, to reduce the environmental pollution, and to achieve the best air-fuel ratio. By adding the regulating device of the present invention, users may compensate for the feedback voltage of the O₂ Sensor using the regulating unit, so that the air-fuel ratio may be adjusted according to the special circumstances to meet diversified demands.
