    摘要: An oxygen concentration detecting device includes at least one oxygen concentration detecting element formed by an oxygen-pumping element and a cell element, composed of an oxygen ion-conductive wall, separating a pair of electrodes. The oxygen-pumping element and cell element define a gas diffusion chamber. A current detecting resistance forms a series circuit with the oxygen-pumping element. A voltage applying circuit applies to the series circuit an output voltage corresponding to the difference between a voltage between the electrodes of the cell element and a first reference voltage. An output detecting circuit outputs a voltage signal corresponding to a value of pumping current flowing through the resistance. An operational amplifier has a non-inverting input terminal supplied with a second reference voltage, an inverting input terminal connected to one end of the resistance, and an output terminal connected to the other end of the resistance. The output detecting circuit detects a first voltage at the one end of the resistance and a second voltage at the other end and outputs the voltage signal corresponding to the difference between the detected first and second voltages. The output detecting circuit corrects the voltage signal based upon the first and second voltages which are obtained in a state where no pumping current is supplied to the resistance. Electrodes of the oxygen-pumping element and the cell element are connected together within the gas diffusion chamber or within the basic body of the sensor body.

    摘要: An output correction method for a proportional-output type O.sub.2 sensor including an oxygen concentration detecting element formed by an oxygen-pumping element and a cell element, each of the oxygen-pumping element and the cell element being composed of a wall of a solid electrolytic material having oxygen ion-conductivity, and a pair of electrodes having the wall interposed therebetween. The oxgen-pumping element is supplied with an output voltage corresponding to a difference between a voltage developed between the electrodes of the cell element and a predetermined reference voltage, and current flowing in the oxygen-pumping element is detected. A correction resistance supplies information indicative of a deviation of an air-fuel ratio detected by the sensor with respect to a predetermined reference air-fuel ratio. A correction value is determined on the basis of the information and the direction of flow of the current. The detected current is corrected by the use of the determined corrected value. A desired air-fuel ratio is calculated on the basis of the corrected current.

    摘要: A method of determining the deterioration of an oxygen concentration sensor for an internal combustion engine. The oxygen concentration sensor includes at least one oxygen concentration sensor element having an oxygen-pumping element and a cell element each composed of a member of a solid electrolytic material having oxygen ion-conductivity, and a pair of electrodes having the member interposed therebetween, and a current-detecting resistance serially connected to the oxygen-pumping element to form a series circuit. A voltage having a magnitude corresponding to a difference between a voltage produced between the electrodes of the cell element and a predetermined reference voltage is applied to the series circuit, and pumping current is detected from a voltage developed across the current-detecting resistance. The predetermined reference voltage is changed from a first predetermined value to a second predetermined value, followed by detecting a difference between a value of said pumping current detected when the predetermined reference voltage assumes the first predetermined value and a value of the pumping current detected when the predetermined reference voltage assumes the second predetermined value. It is determined that there is deterioration in the oxygen concentration sensor when the difference is equal to or greater than a predetermined reference value.

    摘要: An air-fuel ratio control method for an internal combustion engine having an exhaust gas-ingredient concentration sensor provided in an exhaust system and generating an output proportional to the concentration of an ingredient in exhaust gases emitted from the engine. The air-fuel ratio of a mixture supplied to the engine is controlled to a desired air-fuel ratio corresponding to an operating condition in which the engine is operating, in a feedback manner responsive to the output of the sensor. Supply of fuel to the engine is interrupted while the engine is in a predetermined decelerating condition. The method comprises the steps of progressively decreasing the desired air-fuel ratio from a value larger than a value corresponding to the operating condition of the engine to the latter value after the engine leaves the predetermined decelerating condition, and controlling the air-fuel ratio of the mixture supplied to the engine to the progressively decreased air-fuel ratio in the feedback manner.

    摘要: An output correction method for an exhaust gas ingredient-concentration sensor for internal combustion engines. The sensor has two sensor elements having output characteristics different from each other. The sensor elements each produce an output proportional to the concentration of an ingredient in exhaust gases emitted from the engine. The sensor controls the air-fuel ratio of a mixture supplied to the engine to a desired air-fuel ratio by the use of an output from at least one of the sensor elements. First, it is determined whether or not the difference between the desired air-fuel ratio and an actual air-fuel ratio represented by the output of at least one of the sensor elements is smaller than a predetermined value. Then, an output value of one of the sensor elements is corrrected based on an output value of the other of the sensor elements when it is determined that the difference is smaller than the predetermined value.

The wristwatch includes: a solar cell; a control circuit which stops operation under a predetermined condition; and an illuminance detection circuit which indicates illuminance of light irradiating the solar cell being higher than a given threshold value. The wristwatch switches the given threshold value between a first and a second value, larger than the first value, starts the control circuit in a stop state when a signal indicating that the illuminance is higher than the first value is output, receives a satellite signal containing time information from a satellite when a signal indicating that the illuminance is higher than the second value is output, and displays time corresponding to the time information contained in the received satellite signal.
