摘要： A gas concentration measuring apparatus for use in air-fuel ratio control of automotive engines is designed to determine the concentration of oxygen within a wide and a narrow range using a sensor current flowing through a sensor element. The apparatus includes an amplifier circuit equipped with an operational amplifier and a plurality of amplifying resistors and a switch. The switch is responsive to a request signal to switch a relation in electrical connection between an operational amplifier and the amplifying resistors to distribute the amplifying resistors into an input resistor and a feedback resistor for the operational amplifier to change an amplification factor of the amplifier circuit. This results in a change in resolution of measurement of the concentration of oxygen, thereby ensuring enhanced accuracy in determining the concentration of oxygen in a selected one of the narrow and wide ranges.

摘要： An air-fuel ratio sensor is equipped with a sensing element including a solid electrolytic substrate. When the sending element is warmed up and activated by a heater, a microcomputer controls electric power supplied to the heater based on a control base value being set according to a duty ratio=100%. A power profile P1 is determined beforehand to set a target heater power. Through the warm-up heater power control, an actual heater power supplied to the heater is equalized to the target heater power determined according to the power profile P1.

摘要： A gas concentration measuring apparatus is provided which may be employed in measuring an air-fuel ratio of mixture sucked into automotive engines. The apparatus includes a gas concentration sensor exposed to a gas and a voltage applying circuit. The gas concentration sensor is responsive to application of voltage to produce a current signal indicative of concentration of the gas. The voltage applying circuit includes an operational amplifier which operates on a source voltage and which outputs the voltage for developing the voltage applied to the gas concentration sensor which has a level changing as a function of voltage inputted to the operational amplifier. The operational amplifier is designed to have an amplitude of each of the voltages inputted to and outputted from the operational amplifier which falls within a given input/output voltage range defined between an upper limit and a lower limit of a source voltage range and near at least one of the upper and lower limits of the source voltage range, thereby allowing the air-fuel ratio to be measured with higher accuracy over a wide range.

摘要： An A/F sensor generates a current signal corresponding to an air-fuel ratio in response to a voltage applied by a bias control circuit. After a sensor current is received as a voltage signal via a voltage follower, it is outputted to an A/D converter having a predetermined input voltage range, 0 to 5V. A sensor current detection circuit has a plurality of current detection resistors. In order to variably set the resistance value by the sensor current detection circuit, a switch circuit is switched in accordance with the sensor current depending on whether the A/F value to be detected is in the zone near the stoichiometric ratio or in other air-fuel ratio zones.
