The invention claimed is: 1. A system for an engine of a vehicle, comprising: a cylinder of the engine; a first port injector configured to inject a first fuel to said cylinder; a second direct injector configured to inject a second fuel to said cylinder, where said first fuel has a lower alcohol c
The invention claimed is: 1. A system for an engine of a vehicle, comprising: a cylinder of the engine; a first port injector configured to inject a first fuel to said cylinder; a second direct injector configured to inject a second fuel to said cylinder, where said first fuel has a lower alcohol content than said second fuel; and a controller configured to, during a first operating condition, commence combustion in the engine by injecting fuel into said cylinder from only said first injector during a first start, and during a second operating condition, to commence combustion in the engine by injecting fuel into said cylinder from only said second injector during a second start. 2. The system of claim 1 wherein said first fuel includes gasoline and said second fuel includes ethanol. 3. The system of claim 1 wherein said first operating condition is a first temperature, and said second condition is a second temperature, where said first temperature is lower than said second temperature. 4. The system of claim 1 wherein said first operating condition is a first amount of a fuel stored on-board the vehicle, and said second operating condition is a second amount of fuel stored on-board the vehicle, where said first amount is higher than said second amount. 5. A system for an engine of a vehicle, comprising: a cylinder of the engine; a first port injector configured to inject a first fuel to said cylinder; a second direct injector configured to inject said fuel to said cylinder; and a controller configured to, during a first operating condition, commence combustion in the engine by injecting fuel into said cylinder from only said first injector during a first start, and during a second operating condition, to commence combustion in the engine by injecting fuel into said cylinder from only said second injector during a second start; wherein said first operating condition is a first temperature, and said second condition is a second temperature, where said first temperature is lower than said second temperature. 6. The system of claim 5 wherein said first fuel is the same as said second fuel. 7. The system of claim 5 wherein said first fuel includes a first fuel blend, and said second fuel includes a second fuel blend, where said first blend has a higher alcohol content than said second fuel blend. 8. A system for an engine of a vehicle, comprising: a cylinder of the engine; a first injector configured to inject a first substance to said cylinder; a second injector configured to inject a second substance to said cylinder; and a controller configured to perform combustion in the engine by injecting a substance into said cylinder, where said substance is injected by only one of said first and second injectors during selected engine starting conditions, and injection by the other of said injectors is enabled based on a number of combustion events from a start of the engine. 9. The system of claim 8 wherein said first injector is a port injector. 10. The system of claim 9 wherein said second injector is a port injector. 11. The system of claim 8 wherein said first injector is a direct injector. 12. The system of claim 8 wherein said first and second substance are each gasoline. 13. The system of claim 8 wherein said enabling is further based on engine temperature. 14. The system of claim 13 wherein said enabling is further based on an interval since starting. 15. The system of claim 13 wherein said interval is a number of events from said start. 16. A system for an engine of a vehicle, comprising: a cylinder of the engine; a first injector configured to inject a first fuel to said cylinder; a second injector configured to inject a second fuel to said cylinder; and a controller configured to, during a first operating condition, commence combustion in the engine by injecting fuel into said cylinder from at least said first injector during a first start, and during a second operating condition, to commence combustion in the engine by injecting fuel into said cylinder from at least said second injector during a second start, wherein said first operating condition is a first amount of a fuel stored on-board the vehicle, and said second operating condition is a second amount of fuel stored on-board the vehicle, where said first amount is higher than said second amount. 17. The system of claim 16 wherein said first injector is a port injector. 18. The system of claim 17 wherein said second injector is a port injector. 19. The system of claim 16 wherein said first injector is a direct injector. 20. The system of claim 16 wherein said first fuel includes gasoline and said second fuel includes ethanol.
