Abstract:
1. A control apparatus for an internal combustion engine including a first fuel injection mechanism injecting fuel into a cylinder, a second fuel injection mechanism injecting fuel into an intake manifold, a first fuel supply mechanism supplying fuel to said first fuel injection mechanism, and a second fuel supply mechanism supplying fuel to said first fuel injection mechanism and said second fuel injection mechanism, said control apparatus comprising: a control unit controlling said first and second fuel injection mechanisms such that said first and second fuel injection mechanisms partake in fuel injection, including a state of injection from one of said first and second fuel injection mechanisms being ceased, a first abnormality determination unit determining presence of a failure in said first fuel supply mechanism to operate properly, and a second abnormality determination unit determining presence of a failure in said first fuel injection mechanism to operate properly, wherein said control unit effects control such that fuel is injected from at least said first fuel injection mechanism using said second fuel supply mechanism when said first abnormality determination unit determines failure in said first fuel supply mechanism to operate properly and said second abnormality determination unit does not determine presence of failure in said first fuel injection mechanism to operate properly.
