ABSTRACT:
A multipoint fuel delivery system for an internal combustion engine includes fuel metering device(s) such as fuel injector(s) associated for selectively controlled injection of the second fuel to corresponding combustion chamber(s) of the internal combustion engine. A fuel supply manifold associates with fuel injector(s) for directing the second fuel to each fuel injector. An intake port adaptor mechanism adapts the intake port of the associated combustion chamber to receive the selectively controlled injection of the fuel from an associated fuel injector. The intake port adaptor mechanism may also engage the intake port so as to permit selective flow of the first fuel or the second fuel to the intake port of the selected combustion chamber. A control mechanism selectively controls the flow of the second fuel through each injector(s). The multipoint fuel delivery system make practical both dedicated or single-fuel multipoint injection and, alternatively, selective bi-fuel multipoint injection for an internal combustion engine.
