摘要： An intake air amount detecting system which comprises:a temperature-dependent resistor disposed in an intake air path of an internal combustion engine;a sensor control circuit which feeds a heating current to the temperature-dependent resistor, which detects the change in resistance of the temperature-dependent resistor, which amplifies the detected signal, which effects the compensation depending upon the temperature of the intake air, and which controls the heating current in order to maintain the temperature of the temperature-dependent resistor constant; andan operation circuit which converts a signal that represents the heating current into an intake air flow rate;wherein the sensor control circuit is provided with a response-adjusting circuit which delays the response of the heating current only when the intake air flow rate decreases.

摘要： An oxygen concentration control system comprising an electrolyte of the oxygen-ionconduction type exposed on its one surface to the interior of a chamber conducting gases under measurement through a diffusion resistance member, and the system controls the oxygen concentration of gases so that the voltage created across the electrolyte is equal to the predetermined voltage. The inventive system comprises a means for preventing the malfunctioning of the control system caused by the time lag in sensing the oxygen concentration which occurs when the oxygen concentration of the gases varies abruptly or the setting of the oxygen concentration is varied.

摘要： The invention relates to an air flow rate measuring device making use of a hot wire type air flow meter and adapted to measure the true intake air flow rate while compensating for the error attributable to the reversing of the air. The device includes an operation unit adapted to accumulate the output from the hot wire type air flow meter to calculate an apparent intake air flow rate Q.sub.a =Q.sub.1 +Q.sub.2, where Q.sub.1 is the flow rate during reversing of the air while Q.sub.2 represents the flow rate during forward flowing of the air. The apparent flow rate Q.sub.a is discriminated by a signal derived from means for detecting the period in which the reversing of intake air takes place into the flow rate Q.sub.1 in the reversing or backward direction and the flow rate Q.sub.1 in the forward direction, by means of the operation unit. Another operation unit performs the calculation of difference Q.sub.2 -Q.sub.1 to determine the true air flow rate Q.sub.o.
