An engine ECU executes a program including the steps of: determining
presence of abnormality in a low-pressure fuel system; ceasing an intake
manifold injector when determination is made of abnormality in the
low-pressure fuel system; increasing the target purge rate when the
engine operation state attains an injection partaking state between an
in-cylinder injector and an intake manifold injector; reducing the VVT
overlap; and retarding the ignition timing.
