Abstract:
A direct injection engine fuel injection control apparatus comprising:a fuel injection valve injecting fuel directly into a combustion chamber;a combustion switching section, which, in accordance with driving conditions, switches between homogeneous combustion, in which the fuel is injected from the fuel injection valve during an intake stroke and combusted, and stratified combustion, in which the fuel is injected from the fuel injection valve during a compression stroke and combusted;a fuel cutoff section, which, in a predetermined deceleration driving condition, stops injection of the fuel from the fuel injection valve; anda resumption delay section, which, in the case that a fuel-cutoff recovery condition in which the injection of the fuel from the fuel injection valve is resumed after a fuel cutoff is satisfied, and also that a resumption of the injection of the fuel from the fuel injection valve is to be done by the stratified combustion, delays the resumption of the injection of the fuel from the fuel injection valve by a predetermined amount of time.
