摘要： A heating resistor type air flow meter for measuring the amount of air flow which passes through an intake pipe for an internal combustion engine. The air flow meter has a constant-temperature control circuit for detecting air flow, which has a bridge circuit including a heating resistor and a temperature-sensitive resistor each provided in the intake pipe, and a power amplifier circuit for amplifying a signal from the constant-temperature control circuit to generate an air flow signal. The power amplifier circuit has a plurality of amplification resistors which determine a mu-factor for the amplifier to correct the amount of air flow with respect to variation of temperature. At least an amplification resistor has a temperature coefficient different form that of the other amplification resistor, to compensate variation of the mu-factor of the power amplifier circuit.

摘要： An air-fuel ratio control apparatus is disclosed in which an air-fuel ratio sensor disposed in the exhaust system of an internal combustion engine produces a voltage signal correlated with the excess air ratio of the ambient gas surrounding it and has such an output characteristic as to produce a maximum output only when the ambient gas is filled with air, the air-fuel ratio of the internal combustion engine being controlled to a proper value on the basis of the detection signal of the air-fuel ratio sensor. The air-fuel ratio control apparatus further comprises a sampling device for sampling the maximum output (V.sub.x) when it is decided that the output of the air-fuel ratio sensor is maintained for a predetermined length of time or longer at a predetermined value or higher, a memory for storing the sample value of the maximum output (V.sub.x) produced by the sampling device and updating the preceding sample value (V.sub.x-1) to the present sample value (V.sub.x) when a new maximum output is sampled each time of the decision, and a calibrator for calibrating the output characteristic of the air-fuel ratio sensor on the basis of the latest updated sample value (V.sub.x).

摘要： A flow rate of air flowing through an air inlet pipe is detected by a heating resistor disposed therein and converted into an electric signal. A digital processing unit carries out calculation to judge whether or not the converted signal coincides with a predetermined temperature value and to correct the converted signal so that the same is caused to coincide with the predetermined value if both the values do not coincide with each other. The corrected signal is used to keep the heating resistor at the predetermined temperature. The digital processing unit is integrated with the air inlet pipe independently of a digital processing unit for engine control.
