Patent ID: 7185627

Claim:
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 second fuel injection mechanism, said control apparatus comprising: an abnormality determination unit determining presence of abnormality in at least one of said first fuel injection mechanism and said first fuel supply mechanism, a current control valve provided in an intake manifold to control current by altering a whirling state of intake air, and 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, and controlling said current control valve, wherein said control unit controls said current control valve such that said intake air whirls in large circles when said abnormality determination unit determines presence of abnormality in one of said first fuel injection mechanism and said first fuel supply mechanism.
