1. A fuel injection adapter comprising:
- an output port;
a first cavity in fluid communication with the output port, wherein the first cavity is configured to be coupled with at least a portion of a first fuel injector so as to align an output tip of the first fuel injector with the output port and so as to permit a first fuel to be delivered from the first fuel injector through the output port;
a second cavity that is configured to be coupled with at least a portion of a second fuel injector; and
a channel that fluidly connects the second cavity with the first cavity such that a second fuel delivered from the second fuel injector can flow from the second cavity through the channel and through the output port.

Abstract
A fuel injection adapter can include a primary cavity into which a primary fuel injector can be received and a secondary cavity into which a secondary fuel injector can be received. A channel can provide fluid communication between the primary and secondary cavity, and the primary cavity can be in fluid communication with an outlet of the fuel injection adapter.

6. A fuel injection adapter comprising:
-
a connection protrusion that defines an output port, wherein the connection protrusion has a configuration suitable for coupling the fuel injection adapter with an intake manifold of a vehicle; a first sidewall that defines at least a portion of a first cavity, wherein the first sidewall is configured to be coupled with an output end of a first fuel injector that has a configuration identical to the configuration of the connection protrusion, and wherein the first cavity is in fluid communication with the output port; a second sidewall that defines at least a portion of a second cavity, wherein the second sidewall is configured to be coupled with an output end of a second fuel injector; and a channel that fluidly connects the first and second cavities.

11. A fuel injection system comprising:
-
a fuel rail system that defines a first fuel channel and a second fuel channel that are fluidly isolated from each other; a first fuel injector coupled with the fuel rail system, wherein an input tip of the first fuel injector is in fluid communication with the first fuel channel; a second fuel injector coupled with the fuel rail system, wherein an input tip of the second fuel injector is in fluid communication with the second fuel channel; and an adapter comprising; a first cavity; a second cavity; a channel that fluidly connects the first cavity to the second cavity; and an output port in fluid communication with each of the first and second cavities, wherein an output end of the first fuel injector is coupled with the first cavity of the adapter and an output end of the second fuel injector is coupled with the second cavity of the adapter, wherein the fuel injection system is configured to operate in a first operational mode in which a first fuel passes through the first fuel channel of the fuel rail system, through the first fuel injector, and through the output port of the adapter, and wherein the fuel injection system is configured to operate in a second operational mode in which a second fuel passes through the second fuel channel of the fuel rail system, through the second fuel injector, through the channel of the adapter, and through the output port of the adapter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of injecting fuel into an intake manifold via an adapter, wherein the adapter comprises a first cavity and a second cavity that are in fluid communication with each other via a channel, and wherein the adapter further comprises an output port that is in fluid communication with the first cavity, the method comprising:
-
ejecting a first fuel from a first fuel injector such that the first fuel passes through the output port of the adapter, wherein said ejecting the first fuel is performed without altering, via the adapter, a trajectory of at least a portion of the first fuel after the first fuel has exited the first fuel injector; ejecting a second fuel from a second fuel injector; and altering a trajectory of the second fuel via the adapter so as to pass the second fuel through the channel and through the output port. - View Dependent Claims (27)
