<P>PROBLEM TO BE SOLVED: To suppress a fuel injection amount from being corrected to increase more than necessary by the learned value of a feedback correction amount provided in such a state that the fuel injection amount from the injector for intake passage injection is short when a DI ratio r as the ratio of an injection amount from an injector for cylinder injection in an engine having the injector for cylinder injection and the injector for intake passage injection. <P>SOLUTION: An engine ECU performs a program including a step (S114) of prohibiting the updating of a learned value when the temperature T of the injector for intake passage injection is higher than a threshold T(0) (YES in S110) and the injection amount Q is smaller than a threshold Q(0) (YES in S112) in such a state that 0% < DI ratio r < 100% (YES in S106), namely, a fuel is jetted from both injectors. <P>COPYRIGHT: (C)2007,JPO&INPIT |
