Abstract
A method of controlling the mass of fuel delivered to a direct injected engine subject to a change with time in engine load demand. A rate of change of fuel required per cycle of the engine in response to the change in engine load demand is determined. A filter constant is applied to the determined rate of change of fuel required to maintain a value of the rate of change of fuel required at no greater than a predetermined threshold level. The application of the filter constant is dependent upon at least one parameter selected from the group consisting of engine gear, clutch position, vehicle road speed, engine load and engine speed.
