Abstract:
1. A control apparatus for an internal combustion engine at least having an intake manifold injection mechanism injecting fuel into an intake manifold and an in-cylinder injection mechanism injecting the fuel into a cylinder which is provided with an intake valve and an exhaust valve, comprising: a detector detecting information of a deposit formed in said intake manifold; a controller controlling said intake manifold injection mechanism to inject the fuel when said intake valve is closed and when said intake valve is opened, if a predetermined condition associated with said deposit is satisfied; a modifier increasing an amount of the fuel injected through said intake manifold injection mechanism and decreasing an amount of the fuel injected through said in-cylinder injection mechanism, if said predetermined condition associated with said deposit is satisfied; and a prohibiter prohibiting said intake manifold injection mechanism from injecting the fuel when said intake and exhaust valves both open.
