摘要： An electronically controlled fuel injection device for an internal combustion engine during engine acceleration determines a basic amount of injected fuel based on the amount of intake airflow detected by an airflow meter and the engine velocity until the portion filled into the intake air manifold is detected, and then a basic amount of injected fuel based on the data of intake airflow which has been recorded excluding the portion filled into the intake air manifold.

摘要： A setting device of basic fuel injection amount for an internal combustion engine in an operating region of acceleration comparing a detected amount of intake airflow with a retrieved amount of intake airflow stored with the area of opening of a throttle valve and the engine velocity used as parameter, and when the detected amount is less than the retrieved amount, modifying the detected amount on the basis of the change ratio of opening area in the throttle valve, the engine load and the engine velocity, thereby modifying the detected amount so that it is close to the amount required by the engine.
