DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawing.

As shown in FIGS. 1 and 2, there is the preferred embodiment of the voltage detecting regulator with O₂Sensor, except that this embodiment is for description only and that it is not intended to limit the claims.

The detecting regulator A includes a voltage detecting unit 10, as shown in FIG. 1. The voltage detecting unit 10 is connected with the O₂Sensor 06 of the car 05 to detect the feedback voltage of the O₂Sensor 06. The O₂Sensor 06 of the present embodiment is placed on the converging section of the exhaust manifold 07 of the car 05.

A regulating unit 20 is connected to the voltage detecting unit 10, and the regulating unit 20 can compensate the positive or negative value for the feedback voltage of the O₂Sensor 06 by bias voltage. The regulating unit 20 is connected to the car PC computer 08 and transmits the feedback voltage to the car PC computer 08.

A display unit 30 shows the feedback voltage of the O₂Sensor 06, and a bias voltage after adjustment by the regulating unit 20. The display unit 30 can be an analog pressure meter or LCD screen. The display unit 30 can be placed in the car 05 where it is easily seen, such as in the driver seat, so that the driver can check the operation of O₂ Sensor 06 at any time.

The bias voltage of the regulating unit 20 can be manual, and it can also be automatic. When the bias voltage is manual, the regulating unit 20 can have a control component 21 for manual adjustment, such as knob, key, and sticks. The automatic control mentioned herein can have a standard voltage value set in the regulating unit 20. When the feedback voltage of the O₂Sensor 06 is lower than a standard voltage value, the PC computer compensates for the positive value automatically. When the feedback voltage of the O₂Sensor 06 is higher than a standard voltage value, the PC computer compensates for the negative value automatically. By doing so, the feedback voltage of the O₂Sensor 06 is adjusted automatically.

The circuit panel, when the present invention is being operated, is shown in FIGS. 3 and 4. The one shown in FIG. 3 reveals the circuit that can only generate bias voltage, and the one shown in FIG. 4 shows the circuit that can generate positive and negative bias voltage. An IC oscillator 40 and the rectifying transformer circuit 50 are added to supply the negative voltage.

Through the above structure, the operation of the present invention disclosed is explained herein.

When the O₂Sensor is working and generating feedback voltage, the voltage detecting unit 10 starts detecting the feedback voltage of the O₂Sensor 06 and adjusting bias voltage by adjusting the regulating unit 20 for abnormal feedback voltage. The regulating unit 20 compensates for a positive value or negative value to restore the original feedback voltage to keep the air-fuel ration normal. The feedback voltage of the O₂Sensor and the bias voltage after adjustment by the regulating unit 20 can be displayed by the display unit 30 for the driver to detect. When the bias voltage of the regulating unit 20 is manual control, users may adjust the bias voltage for the control component 31 by the regulating unit 20 under various circumstances mentioned herein, such as when the vehicle is going up hill and the engine is overheating. The air-fuel ratio is changed by compensating the feedback voltage of the O₂Sensor 06, this feature allowing a user and manufacturers to meet the diversified demands and practicality in applications.

Moreover, the O₂Sensor 06 disclosed in the present invention can be placed on a vehicle. Even though motorcycle technology is progressing, only the heavier motorcycles have exhaust similar to a small car; therefore there is the possibility of an added O₂Sensor on the motorcycle. For these reasons, the regulating device A mentioned above is not limited to the car use, and it may be applied to other transportation vehicles that contains O₂Sensor.
