ABSTRACT:
An Engine ECU executes a program including the steps of: calculating (S100) a wall deposit correction quantity fmw, a DI reference injection quantity taudb of an in-cylinder injector, and a PFI reference injection quantity taupb of an intake manifold injector; sensing (S200) an engine coolant temperature THW; if THW is higher than a THW threshold value (YES in S300) and DI ratio r is not 100% (NO in S400), making a correction (S600) with wall deposit correction quantity fmw using the intake manifold injector; if THW is at most THW threshold value (NO in S300), making a correction (S500) with wall deposit correction quantity fmw using the in-cylinder injector.
