Estimating the term…
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.
A multipoint bi-fuel engine capable of using a first fuel and a second fuel, comprising:
A multipoint fuel injection method for introducing an alternative fuel into an internal combustion engine designed to operate with a conventional fuel, the engine having a plurality of combustion chambers, each combustion chamber having an intake port, the method comprising the steps of:
An intake port adapter system for providing multipoint fuel delivery to an internal combustion engine the engine being a conventional engine having a fuel system that operates with a conventional fuel, the engine having a plurality of combustion chambers, each combustion chamber having an intake port, each intake port having a diameter, the system comprising:
