<P>PROBLEM TO BE SOLVED: To appropriately correct fuel adhered on a port wall surface even if change in DI ratio r (0<r<1) in an internal combustion engine equipped with an injector for cylinder injection and an injector for intake passage injection. <P>SOLUTION: An engine ECU300 executes a program including a step (S100) for calculating a correction factor fmw, a basic injection amount taupb of an injector 120 for intake passage injection, a basic injection amount taudb of an injector 110 for cylinder injection in wall surface adhesion and a step (S300) for substituting taudb+(taupb-taumin) for a final injection amount taud of the injector 110 for cylinder injection in case of taupb-taumin<0 (YES in S200) and substituting taumin+tauv for a final injection amount taup of the injector 120 for intake passage injection. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
