Abstract
A fuel-injection system for an internal combustion engine that operates in a stratified mode of fuel injection during a first engine speed range and a homogeneous mode of fuel injection during a second engine speed greater than the first range. A changeover speed is determined for a particular engine and, upon speed (or load) increasing to the point of changeover from the stratified mode, the engine speed update point changes from a first or 'standard' update point to a second predetermined 'provisional' update point for one or two revolutions after which the update point then reverts back to the 'standard' update point.
