Method of setting fuel injection timing for direct-injection spark-ignition engine

A direct-injection spark-ignition engine in which a combustible mixture is produced around a spark plug at an ignition point by causing a tumble and a fuel spray to collide with each other in a combustion chamber during stratified charge combustion comprises a fuel pressure controller which controls fuel pressure such that penetration of the fuel spray from a fuel injector is progressively intensified with an increase in engine speed in a stratified charge combustion region and means for controlling fuel injection timing including an injection timing setter. The means for controlling fuel injection timing controls the injection timing in such a way that the interval between a fuel injection ending point and the ignition point becomes progressively shorter as engine speed increases under the same engine load conditions in the stratified charge combustion region.
