Abstract
A fuel injection rate control system for a fuel-injection internal combustion engine, wherein basic fuel injection rate signals are produced upon detection of the load on the engine and the engine output speed and are modified by the correction values read out from a collection of data indicating various correction values in terms of the engine output speed and the engine load. When the correction values selected are zeros or smaller than a predetermined value, the fuel injection rate may be controlled to achieve a predetermined air/fuel ratio in the engine through detection of the air/fuel ratio of the mixture produced in the engine.
