Abstract
A fuel injection control system for an automotive engine, including a device which, before an intake stroke cycle, estimates what an estimated throttle opening degree and an estimated engine speed will be for the engine after a predetermined time period in the intake stroke cycle has lapsed, based on the throttle opening degree and engine speed and calculates a first fuel injection quantity to be injected before an intake stroke cycle, and a device which, during the intake stroke cycle, calculates a second fuel injection quantity and computes an asynchronous interrupted fuel injection quantity to be injected during the intake stroke cycle, based on the difference between the first and second fuel injection quantity.
