ABSTRACT:
An engine ECU executes a program including the steps of: detecting a fuel pressure in a high-pressure fuel system (S130) if a lock-up clutch is not in a released state (NO at S100) and if a tip end temperature of an in-cylinder injector is equal to or lower than a temperature threshold value (NO at S120); calculating fuel pressure lowering ΔP as a result of fuel injection from the in-cylinder injector (S140); calculating fuel shortage amount ΔQ corresponding to fuel pressure lowering shortage (S170) if ΔP is smaller than a fuel pressure threshold (YES at S150); and injecting fuel from an intake manifold injector in an amount obtained by adding ΔQ to an amount of fuel injection from the intake manifold injector of a cylinder (S180).
