摘要： A fuel supply control system for an internal combustion engine comprises deceleration detecting device for detecting a predetermined decelerating condition of the engine, and fuel supply decreasing device for decreasing the supply of fuel to the engine when the predetermined decelerating condition is detected by the deceleration detecting device. A first counting device starts to count a first predetermined time period when the high-load detecting device detects that the engine has left the predetermined high-load condition. An inhibiting device inhibits the fuel supply decreasing device from operating when the deceleration detecting device detects the predetermined decelerating condition of the engine before the first counting device completes counting the first predetermined time period. A second counting device counts a second predetermined time period while the high-load detecting device is detecting the predetermined high-load condition of the engine. The first counting device starts to count the first predetermined time period when the second counting device has completed counting the second predetermined time period. An intake air increasing device increases the amount of intake air supplied to the engine while the inhibiting device is operating.

摘要： A method of controlling in a feedback manner the air-fuel ratio of an air-fuel mixture supplied to an internal combustion engine having a first fuel injection valve and a second fuel injection valve each operating in a different operating region, during operation of the engine in an air-fuel ratio feedback control region, by the use of a coefficient which varies with the output of an exhaust gas ingredient concentration sensor. In a first and a second operating regions within the air-fuel ratio feedback control region in which the first and second fuel injection valves operate, respectively, a first average value and a second average value of values of said coefficient obtained in the respective regions are calculated, and stored, respectively. When the engine has shifted to the first or and second operating regions, a value based on the corresponding first or second average value is used as an initial value of the coefficient to therely start the feedback control. Preferably, in a third operating region defined as a predetermined period of time which elapses after the engine has shifted from the second operating region to the first operating region, a third average value of values of the coefficient obtained in the third operating region is calculated and stored, and when the engine shifted to the third operating region, the third average value is used as an initial value of the coefficient to thereby start the feedback control.

摘要： In an I/V converter circuit and a D/A converter, a wide pass band for signal can be obtained and current consumption can be reduced. A current is supplied through an input terminal to a first node, and a first bias current is supplied from a first bias-current generating circuit to the first node. The current supplied to the first node is mirrored to a second node, and a second bias current is supplied from a second bias-current generating circuit to the second node. A first control circuit controls first and second elements of a current mirror circuit so that the voltage of the first node is substantially equal to a bias voltage, a third element converts a current flowing therethrough to a voltage by using the bias voltage as reference, and a second control circuit controls the voltage output from an output terminal so that the voltage of the second node is substantially equal to the bias voltage.
