CLAIMS

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, said ratio including preventing one of said fuel injection mechanisms from injecting the fuel; and
an ignition timing controller controlling an ignition device to vary a timing of ignition, wherein said ignition timing controller controls said ignition device, as based on a reference timing of ignition of said internal combustion engine determined from said ratio.

2. 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, said ratio including preventing one of said fuel injection mechanisms from injecting the fuel;
a storage storing a reference timing of ignition; and
an ignition timing controller employing said reference timing of ignition to control an ignition device, wherein said storage stores said reference timing of ignition calculated as based on said ratio.

3. The control apparatus according to claim 2, wherein said storage stores in a form of a map said reference timing of ignition previously calculated as based on said ratio.

4. The control apparatus according to claim 3, 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.

5. The control apparatus according to claim 4, wherein said first map provides said reference timing of ignition set to provide spark advance.

6. The control apparatus according to claim 4, wherein said second map provides said reference timing of ignition set to provide spark retard.

7. The control apparatus according to claim 4, wherein said third map provides said reference timing of ignition set to provide spark advance when said first fuel injection mechanism is increased in said ratio.

8. The control apparatus according to claim 4, wherein said third map provides said reference timing of ignition set to provide spark retard when said second fuel injection mechanism is increased in said ratio.

9. The control apparatus according to any of claims 1-8, wherein said first fuel injection mechanism is an in-cylinder injector and said second fuel injection mechanism is an intake manifold injector.

10. A control apparatus for an internal combustion engine having first fuel injection means for injecting fuel into a cylinder and second fuel injection means for injecting the fuel into an intake manifold, comprising:
control means for controlling said first and second fuel injection means to bear shares, respectively, of injecting the fuel at a ratio calculated as based on a condition required for said internal combustion engine, said ratio including preventing one of said fuel injection means from injecting the fuel; and
ignition timing control means for controlling an ignition device to vary a timing of ignition, wherein said ignition timing control means includes means for controlling said ignition device, as based on a reference timing of ignition of said internal combustion engine determined from said ratio.

11. A control apparatus for an internal combustion engine having first fuel injection means for injecting fuel into a cylinder and second fuel injection means for injecting the fuel into an intake manifold, comprising:
control means for controlling said first and second fuel injection means to bear shares, respectively, of injecting the fuel at a ratio calculated as based on a condition required for said internal combustion engine, said ratio including preventing one of said fuel injection means from injecting the fuel;
storage means for storing a reference timing of ignition; and
ignition timing control means employing said reference timing of ignition for controlling an ignition device, wherein said storage means includes means for storing said reference timing of ignition calculated as based on said ratio.

12. The control apparatus according to claim 11, wherein said storage means includes means for storing in a form of a map said reference timing of ignition previously calculated as based on said ratio.

13. The control apparatus according to claim 12, wherein said storage means includes means for storing said reference timing of ignition divided into a first map applied when said first fuel injection means alone injects the fuel, a second map applied when said second fuel injection means alone injects the fuel, and a third map applied when said first and second fuel injection means inject the fuel.

14. The control apparatus according to claim 13, wherein said first map provides said reference timing of ignition set to provide spark advance.

15. The control apparatus according to claim 13, wherein said second map provides said reference timing of ignition set to provide spark retard.

16. The control apparatus according to claim 13, wherein said third map provides said reference timing of ignition set to provide spark advance when said first fuel injection means is increased in said ratio.

17. The control apparatus according to claim 13, wherein said third map provides said reference timing of ignition set to provide spark retard when said second fuel injection means is increased in said ratio.

18. The control apparatus according to any of claims 10-17, wherein said first fuel injection means is an in-cylinder injector and said second fuel injection means is an intake manifold injector.
