<p>An engine ECU executes a program including the steps of: detecting a fuel pressure in a high-pressure fuel system (S 130 ) if a lock-up clutch is not in a released state (NO at S 100 ) and if a tip end temperature of an in-cylinder injector is equal to or lower than a temperature threshold value (NO at S 120 ); calculating fuel pressure lowering DeltaP as a result of fuel injection from the in-cylinder injector (S 140 ); calculating fuel shortage amount DeltaQ corresponding to fuel pressure lowering shortage (S 170 ) if DeltaP is smaller than a fuel pressure threshold (YES at S 150 ); and injecting fuel from an intake manifold injector in an amount obtained by adding DeltaQ to an amount of fuel injection from the intake manifold injector of a cylinder (S 180 ).</p> |
