Abstract
An engine ECU executes a program including the step of closing a current control valve in all regions when there is abnormality in a high-pressure system fuel system (YES at S100), the step of setting the VVT overlap to 0, the step of injecting fuel from only an intake manifold injector, the step of corresponding to an ignition timing when the current control valve is closed, and the step of correcting the increased quantity of fuel.
Claims21
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.
A control apparatus for an internal combustion engine including first fuel injection means for injecting fuel into a cylinder, second fuel injection means for injecting fuel into an intake manifold, first fuel supply means for supplying fuel to said first fuel injection means, and second fuel supply means for supplying fuel to said second fuel injection means, said control apparatus comprising:
- abnormality determination means for determining presence of abnormality in at least one of said first fuel injection means and said first fuel supply means,
- a current control valve provided in an intake manifold to control current by altering a whirling state of intake air, and
- control means for controlling said first and fuel injection means such that said first and second fuel injection means partake in fuel injection, including a state of injection from one of said first fuel injection means and said second fuel injection means being ceased, and controlling said current control valve,
- wherein said control means comprises means for controlling said current control valve such that said intake air whirls in large circles when said abnormality determination means determines presence of abnormality in one of said first fuel injection means and said first fuel supply means.
