초록 ▼

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.

대표청구항 ▼

[ What is claimed is:] [1.] A multipoint bi-fuel engine capable of using a first fuel and a second fuel, comprising:an engine capable of using the first fuel and comprising at least one combustion chamber, each combustion chamber having an intake port;at least one fuel metering device for selectively controlled injection of the second fuel to a corresponding one of the at least one combustion chamber;a fuel supply manifold associated with said at least one fuel metering device for directing the second fuel to each of said at least one fuel metering device;an intake port adapter mechanism for adapting the intake port of a selected one of said at least one combustion chamber to receive the selectively controlled injection of the second fuel from a selected one of said at least one fuel metering device, said intake port adapter mechanism engaging the intake port for selectively flowing the second fuel to the intake port of the selected combustion chamber;at least one fuel supply hose each said hose having a first end coupled to one of said at least one fuel metering device and having a second end coupled to said intake port adapter mechanism; anda control mechanism for selectively controlling the flow of the second fuel through each of said at least one fuel metering device.
