ABSTRACT:
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.
