摘要： An input processing circuit for an air flow sensor comprising a differential amplifier connected through two lines to an air flow sensor and having an operational amplifier an output signal from the air flow sensor and sends a result of this processing to an analogue value - digital value conversion integrated circuit. An output signal from the air flow sensor is supplied to the differential amplifier through a filter circuit so as to prevent an occurrence of error in measuring the amount of sucked air for an internal combustion engine due to various noises. A connection of an inverting input terminal end of the differential amplifier to a ground through a resistor prevents an error caused by a breakage of a reference voltage line connected between the air flow sensor and the input processing circuit. A differential input amplifier circuit also prevents an error caused by a variation in potential resulting from consumption current of an air flow sensor or the like from being generated.

摘要： The invention relates to a novel fuel controller of an internal combustion engine. In particular, it relates to a novel fuel controller which securely corrects characteristic variation with time of air-flow sensor used for controlling flow of fuel. The fuel controller embodied by the invention incorporates a memory which stores the negative feedback correction value of air-fuel ratio or the value related to it at the flow-volume point representing variation of characteristic of air-flow sensor or at an adjacent point of it so that the basic volume needed for controlling flow of fuel can be corrected by applying the content of memory. As a result, even if characteristic of the air-flow sensor varies, the system can achieve satisfactory control condition. The fuel controller inhibits renewal of the study on the negative feedback correction value for the predetermined period in accordance with the opening/closing condition of the purge-control valve. As a result, the fuel controller can securely and constantly perform satisfactory fuel-flow control operation without being influenced by erroneous air-fuel ratio caused by presence of purged gas.
