子燃料噴射式エンジンの燃料制御装置。 An air flow meter installed in the intake system to detect the amount of intake air, a load detection means that outputs a signal corresponding to the intake negative pressure downstream of the throttle valve or the opening degree of the throttle valve, and an engine rotation speed detector to detect the engine rotation speed. means, first fuel control means for controlling the fuel injection valve based on the output of the air flow meter, and second fuel control means for controlling the fuel injection valve based on the outputs of the load detection means and the engine rotation speed detection means. In an operating region where the intake air amount or engine load exceeds a predetermined value, the fuel injection amount control based on the first fuel control means is changed to the second fuel injection amount control based on the first fuel control means.
a switching means for switching to fuel injection amount control based on the fuel control means; a transient detection means for detecting a transient state of the engine; and a transient detection signal outputted from the transient detection means, which is directly received and based on the first fuel injection amount control. a first transient correction value calculation means for calculating a first transient correction value for correcting the fuel injection amount calculated by the control means; and a first transient correction value calculation means that directly receives a transient detection signal output from the transient detection means, 2. A second transient correction value calculation means for calculating a second transient correction value for correcting the fuel injection amount calculated by the fuel control means, and a fuel injection amount calculated by the fuel control means to be at least selected based on the transient correction value. 1. A fuel control device for an electronic fuel injection engine, comprising: transient correction means for correcting.
