Abstract:
1. A control apparatus for an internal combustion engine having a first fuel injection mechanism injecting fuel into a cylinder and a second fuel injection mechanism injecting the fuel into an intake manifold, comprising: a controller controlling said first and second fuel injection mechanisms to bear shares, respectively, of injecting the fuel at a ratio calculated as based on a condition required for said internal combustion engine; a storage storing a reference timing of ignition; and an ignition timing controller always employing at least said reference timing of ignition to control an ignition device, wherein said first and second fuel injection mechanisms bear shares, respectively, of injecting the fuel; wherein said storage stores said reference timing of ignition to provide spark advance when said first fuel injection mechanism is increased in said ratio; wherein said storage stores in a form of a map said reference timing of ignition previously calculated as based on said ratio; and wherein said storage stores said reference timing of ignition divided into a first map applied when said first fuel injection mechanism alone injects the fuel, a second map applied when said second fuel injection mechanism alone injects the fuel, and a third map applied when said first and second fuel injection mechanisms inject the fuel.
