<p>Disclosed is a fuel-injection system controlling method and an apparatus therefor, in which a running status of an engine (5) is successively detected so as to determine a fuel-injection time on the basis of a fuel-injection pulse width and a quantity of pulse width correction in accordance with the detected engine running status. In the method and apparatus, there is provided a map (l) having a plurality of areas corresponding to various running statuses of the engine (5), each of said areas having a quantity of pulse width correction written therein, so that when the engine running status has varied from a certain one area to another one of the map, the boundary of the certain one area is expanded by a predetermined quantity, and if a current engine running status exists in the area encircled by the expanded boundary the pulse width correction quantity is not changed but if the current engine running status exists in a different area outside the area encircled by the expanded boundary the final fuel-injection pulse width is determined on the basis of the pulse width correction quantity written in the different area.</p> |
