Patent ID: 7007667

Claim:
An engine startup fuel control system for use with an internal combustion engine of the type having a plurality of combustion chambers, an intake air passage fluidly connected each combustion chamber and a source of fuel, said fuel control system comprising: a multipoint fuel injector associated with each combustion chamber, each multipoint fuel injector having an inlet connected to said fuel source and an outlet fluidly connected to said intake air passageway adjacent its associated combustion chamber, a cold start fuel injector having an inlet connected to said fuel source and an outlet fluidly connected through a cold start passageway with each combustion chamber, processing means for selectively activating each of said multipoint fuel injectors and said cold start fuel injector, said processing means having means for determining the air/fuel mixture introduced by said cold start fuel injector into at least one combustion chamber during engine startup, said processing means having means responsive to said determining means for selectively activating each said multipoint fuel injector to achieve a predetermined air/fuel mixture in each combustion chamber during engine startup.
