Method and system of thermochemical regeneration to provide oxygenated fuel, for example, with fuel-cooled fuel injectors
First Claim
1. A fuel-cooled fuel injector configured to inject fuel into a combustion chamber, the fuel injector comprising:
- a body having a base portion opposite a nozzle portion, wherein the base portion is configured to receive the fuel into the body and the nozzle portion is configured to be positioned adjacent to the combustion chamber;
a valve carried by the nozzle portion, wherein the valve is movable between a closed position and an open position to inject the fuel into the combustion chamber;
an actuator coupled the valve and extending longitudinally through the body towards the base portion, the actuator includes a stop in the base portion;
a driver independent of the valve and the actuator carried by the body and movable between a first position and a second position, in the first position the driver is spaced apart from the stop and in the second position the driver contacts the stop to move the actuator axially away from the nozzle portion to move the valve to the open position; and
a plurality of passageways extending longitudinally through the driver configured to allow fuel to flow therethrough.

Abstract
The present disclosure is directed to integrated injector/igniters providing efficient injection, ignition, and complete combustion of various types of fuels. One example of such an injectors/igniter can include a body having a base portion opposite a nozzle portion. The base portion receives the fuel into the body and the nozzle portion can be positioned adjacent to the combustion chamber. The injector further includes a valve carried by the nozzle portion that is movable between a closed position and an open position to inject the fuel into the combustion chamber. An actuator is coupled the valve and extends longitudinally through the body towards the base portion, and a driver is carried by the body and is movable between a first position and a second position. Thermochemical regeneration of waste heat produced by combustion and associated combustion events is captured and invested in endothermic reactions to improve efficiency of the combustion event. Hydrogen characterized fuel may be used as a heat sink.

15. A method for providing oxygenated fuel to a combustion chamber of a fuel injector comprising:
-
capturing waste heat from a source derived from a heat engine to drive endothermic reactions; transporting steam from a combustion event occurring in a combustion chamber of a fuel injector through capillaries in a body of the fuel injector; combining the waste heat with the steam wherein the waste heat is at a first temperature and the steam is at a second higher temperature than the waste heat; and reacting methane with steam to produce carbon monoxide and hydrogen. - View Dependent Claims (16)

17. A fuel injector configured to inject fuel into a combustion chamber, the fuel injector comprising:
-
a body having a base portion opposite a nozzle portion, wherein the base portion is configured to receive the fuel into the body and the nozzle portion is configured to be positioned adjacent to the combustion chamber; a valve at the nozzle portion, wherein the valve is movable between a dosed position and an open position; an actuator having a first end coupled to the valve and a second end portion opposite the first end portion, wherein the second end portion has a stop; a driver separable from the valve and the actuator positioned in the body and movable between first and second positions, in the first position the driver is spaced apart from the stop and in the second position the driver contacts the stop to move the actuator axially away from the nozzle portion to move the valve to the open position; and a countercurrent heat exchanger configured to exchange heat from exhaust gases to fuel in the body. - View Dependent Claims (18, 19, 20)
