  In many engines, particularly in large engines, the size of the hole or port through which the fuel injector enters the combustion chamber is small. Thus, this small port limits the size of components that can be used to move fuel from the injector or otherwise inject it. In addition, such engines are also typically densely populated with intake and exhaust valve train mechanisms and have limited space available for these fuel injection system components.

1 is a schematic side cross-sectional view of an integrated injection / ignition device (referred to as an “injection device”) configured in accordance with an embodiment of the present invention. It is a side sectional view of an injection device constituted according to other embodiments of the present invention.

  FIG. 1 is a schematic cross-sectional side view of an integrated injector / igniter 100 (referred to as “injector 100”) constructed in accordance with certain embodiments of the present disclosure. The injector 100 of FIG. 1 is intended to schematically illustrate some of the features of an injector and assembly configured in accordance with embodiments of the present disclosure. Accordingly, the features described in connection with FIG. 1 are not intended to limit any of the injector and assembly features described below. As shown in FIG. 1, the injection device 100 includes a body 102 having an intermediate portion 104 extending between a first end or base 106 and a second end or nozzle portion 108. . The nozzle portion 108 extends at least partially through the engine head 110 and is configured to inject and ignite fuel at or near the junction 111 with the combustion chamber 112. As will be described in detail below, the injector 100 is particularly suitable for providing optimal and fast fuel injection when fueling at high pressure while providing rapid ignition and complete combustion within the combustion chamber 112. Yes.

  The injection device 100 also includes an ignition function unit 114 such as a conductive electrode carried by the nozzle unit 108. The ignition function part 114 is installed in the vicinity of the joint part 111 of the combustion chamber 112, and is configured to ignite fuel passing through the ignition function part 114 through the nozzle part 108. The ignition function 114 is operatively connected to a conductor 116 that extends through the body 102. The conductor 116 extends from the nozzle portion 108 through the intermediate portion 104, and at least a part thereof can further extend to the base portion 106 as necessary. For example, in certain embodiments, the conductor 116 can extend through the base 106. As will be described in detail below, the conductor 116 is connected to one or more energy sources that provide ignition energy or voltage. For example, the conductor 116 can be connected to an energy source at the base 106 or the intermediate portion 104 of the body 102. Therefore, the conductor 116 can supply the ignition function unit 114 with ignition energy for igniting the fuel by heating the filament and / or plasma DC or AC plasma.

  The injector 100 further includes a fuel adjustment valve 118 and a valve actuation assembly 128 carried by the base. In FIG. 1, the valve 118 is shown schematically as being installed in the base 106, but in other embodiments the valve is located elsewhere in the injector 100, such as the nozzle portion 108 and / or Alternatively, it can be installed in the intermediate portion 104. In addition, in some embodiments, the valve 118 can extend through multiple portions of the body 102, eg, throughout the body 102. Further, although only one valve 118 is depicted in FIG. 1, in other embodiments, the injector 100 can include two or more valves carried at various locations on the body 102. Further, any of the features of the injector 100 described herein with respect to FIG. 1 are described in detail in the patents and patent applications cited above and elsewhere herein, which are incorporated herein by reference in their entirety. Can be used in connection with any of the injectors described in.

  The valve actuation assembly 128 is configured to actuate or otherwise move the valve 118 to cause the fuel to flow through the body 102 and introduce the fuel into the combustion chamber 112. Yes. More specifically, the valve actuation assembly 128 activates the plunger mover or driver 120 or otherwise induces its movement (eg, by generating a magnetic force in one embodiment). Includes a force generator assembly 122. Driver 120 is configured to move or otherwise actuate valve 118. For example, in certain embodiments, the driver 120 moves from a first position to a second position to contact or hit the valve 118, thereby moving the valve 118 from a closed position to an open position. Can do. However, in other embodiments, for example when a regulating valve is installed in the nozzle portion 108, the driver 120 contacts or is in contact with an actuator, such as a plunger, rod or cable, operatively connected to the valve. Can be moved.

  According to other features of the illustrated embodiment, force generation assembly 122 can be an electrical, electromechanical and / or electromagnetic force generation device that operates as a transformer. For example, in the illustrated embodiment, the force generator assembly 122 includes a primary or first force generator 124 proximate to a secondary or second force generator 126. Although only two force generators are shown in FIG. 1, in other embodiments, the force generator assembly 122 may include three or more separate force generators, such as three or more force generators. Can be included. In certain embodiments, the first force generator 124 can be a piezoelectric element that can be actuated to provide a force to move the valve 118. In other embodiments, the first force generator 124 can be a solenoid winding. Further, the second force generator 126 can also be a piezoelectric element or a solenoid winding. The first solenoid 124 can be connected to an energy supply that supplies current to the first solenoid 124 (eg, pulsed or intermittent direct current). The second solenoid 126 is conductively connected to the conductor 116 via an electrically insulated solenoid conductor 130. Therefore, the second solenoid 126 is electrically connected to the ignition function unit 114.

  During operation, the force generation assembly 112 consequently functions as a transformer that provides a motive force for injecting fuel from the injector 100 into the combustion chamber 112. The force generation assembly 122 also provides ignition energy to at least partially initiate ignition of the fuel injected into the combustion chamber 112. For example, when current is applied to the first solenoid 124, the first solenoid 124 generates a force that actuates or otherwise moves the driver 120, such as a magnetic or magnetic flux. As driver 120 moves in response to first solenoid 124, driver 120 now activates valve 118 to inject fuel into combustion chamber 112. For example, the driver 120 can contact the valve 118 directly or with the valve actuator to move the valve 118 to the open position. Further, the magnetic field from the first solenoid 124 induces ignition energy or voltage in the second solenoid 126. Since the second solenoid 126 is electrically connected to the ignition function 114 via the conductor 116, the second solenoid 126 consequently results in at least ignition energy (eg, to initiate fuel ignition). Voltage and / or current) can be supplied to the ignition function 114. In certain embodiments, current can be supplied to the second solenoid 126 to induce movement of the driver 120. As such, the second solenoid 126 can consequently assist or assist in controlling the movement of the valve 118 by the first solenoid 124. In certain embodiments, the first solenoid 124 can be operated at about 10 to 1,000 volts and the second solenoid 126 can be induced to provide at least about 10,000 volts.

  In embodiments where the first and second force generators 124, 126 are solenoid windings, the first solenoid 124 may be in a separate circuit from the second solenoid 126. However, in other embodiments, the first solenoid 124 can be placed in parallel with the second solenoid 126 in a circuit. In other embodiments, the first solenoid 124 can be placed in series with the second solenoid 126 in a circuit. Further, the first solenoid 124 may be disposed concentrically with the second solenoid 126 in the base 106. Although the first solenoid 124 of FIG. 1 is shown as being positioned radially outward of the second solenoid 126, in other embodiments, the first solenoid 124 is connected to the second solenoid 126. It can be positioned radially inward. However, in other embodiments, the first solenoid 124 and the second solenoid 126 can be installed or arranged in other configurations, for example as a non-concentric arrangement to increase package efficiency within the base 106. Also good.

  According to other features of the embodiment of the force generation assembly 122 that includes a solenoid winding force generator, in certain embodiments, the cross-sectional dimension (diameter) of the winding conductor of the first solenoid 124 is set to the second solenoid. The 126 winding conductors can be made larger than their corresponding cross-sectional dimensions (diameters) to receive a larger current flowing through the first solenoid 124. For example, in one embodiment, the diameter of the winding conductor of the first solenoid 124 can be about 10 times larger than the diameter of the winding of the second solenoid 126. However, in other embodiments, the diameter of the winding conductor of the first solenoid 124 can be about 10 times or more than the diameter of the winding conductor of the second solenoid.

  In yet another embodiment, the force generation assembly 122 functions as a transformer, so that the desired or predetermined ratio depends on the ratio of turns or revolutions of the winding conductors of the first solenoid 124 and the second solenoid 126. In order to obtain the induction ignition energy or the voltage for supplying the ignition energy, the ignition energy or voltage induced by the second solenoid 126 can be increased or decreased. For example, the number of turns or rotation of the second solenoid 126 can be increased from that of the first solenoid 124 to increase the induction ignition energy or voltage in the second solenoid 126. For example, in one embodiment, the number of turns or rotation of the second solenoid 126 can be ten times greater than that of the first solenoid 124. However, in other embodiments, this ratio can be adjusted to obtain the desired induction ignition energy or voltage at the second solenoid 126. In this manner, the second force generator 126 is configured to cause an ignition event (eg, initial heating and / or plasma generation) by applying a relatively low current to the first force generator 124. it can. The winding conductors of the first solenoid 124 and the second solenoid 126 can also be properly insulated to prevent short circuits during operation, particularly during operation at high pressure.

  In certain embodiments, the first force generator 124 can include a plurality of primary solenoid windings. For example, the plurality of primary windings may have opposite polarities (eg, + or-) or different ignition energy or voltage so that the period of periodic motion of the valve 118 and / or the second force generator. Movements including ignition energy or voltage induced at 126 can be more finely tuned.

  According to other features of the embodiment shown in FIG. 1, the injector 100 may include ignition energy or voltage supply conductors 131. The voltage supply conductor 131 may be connected to a suitable ignition energy or voltage source that is separate from the force generation assembly 122, and more particularly, separate from the second solenoid 126. The voltage supply source 131 can also be electrically connected to the ignition function unit 114 via the conductor 116. Therefore, the voltage supply conductor 131 can supply ignition energy for causing the ignition function unit 114 to generate an ignition event. Therefore, the voltage supply conductor 131 can supply ignition energy separately from and together with the second solenoid 126. Although the voltage supply conductor 131 is connected to the conductor 116 at the intermediate portion 104 of the body 102, in other embodiments, the voltage supply conductor 131 can be connected to the conductor 116 at the base portion 106 of the body 102.

  In the illustrated embodiment, the base 106 may also include a fixation plate, case or housing 129 that at least partially surrounds the force generation assembly 122. The housing 129 can be a metal housing, which can be a shield, such as a radio (RF) shield for the force generating assembly 122, for example. For example, the housing 129 can shield the force generating assembly 122 from other RF equipment or sources during operation. The housing 129 can further prevent the force generation assembly 122 from receiving or interfering with other RF equipment or sources.

  Injector 100 may further include a sensor or other device configured to detect an operating condition. For example, the injector 100 can include a fiber optic cable, at least partially through the body 102, or other sensor installed in the nozzle portion 108, which is configured to detect combustion chamber characteristics. (Illustrated and described below with reference to sensor device element 290 of FIG. 2). The valve actuation assembly 128 and / or force generation assembly 122 can consequently be optimally controlled depending on one or more conditions of the combustion chamber.

  In operation, fuel is introduced into the base 106 and exits the base 106 and enters a fuel flow path or path 117. The fuel flow path 117 extends from the base portion 106 through the central portion 104 to the nozzle portion 108 so as to pass through the main body 102. The injector 100 allows a precisely measured amount of fuel to be selectively and optimally introduced into the combustion chamber 112 through the fuel flow path 117. For example, the driver 120 operates the valve 118 to slide, rotate, or otherwise move from the closed position to the open position. Force generation assembly 122 controls the movement of valve 118. More particularly, force generation assembly 122 controls (1) the flow rate of fuel by opening valve 118 and / or other valve assemblies, and (2) by heating and / or ionization when the valve opening operation is complete. It is configured to generate ignition energy or voltage. As described above, to achieve both of these functions, the force generation assembly 122 includes a first or primary winding 124 or first piezoelectric element 124 and a secondary winding 126 or second piezoelectric element 126. And a solenoid winding including: The number of turns of the solenoid winding 126 can be larger than that of the first winding 14. Each winding may include one or more insulating layers (eg, varnish or other suitable insulator), but the second winding 126 has more than the first winding 124. Insulating layers may be included. The force generation assembly 122 can also be electrically connected to the conductor 116. To generate a pull of the driver 120 or plunger mover by winding the force generating assembly 122 or solenoid as a transformer with a greater number of turns of the first winding 124 and the second winding 126, or When ignition energy or voltage is applied to induce motion, the primary winding 124 can carry a large current. When the relay to the primary winding 124 is released, the driver 120 is released and very high ignition energy or voltage is generated by the secondary winding 126. The high ignition energy or voltage of the secondary winding 126 is available for heating and / or plasma generation ignition events by initial heating and / or ionization of the ignition function 114 via the conductor 116, after which the injection By relatively low ignition energy or voltage release of a capacitor carried by the device 100 and already charged by a suitable source (including photovoltaic, electrothermal, energy recovered from the combustion chamber by a piezoelectric generator) Subsequently, ionization current and fuel injection are supplied to the combustion chamber 112.

  Further, during operation, the injector 100 can adjust injection and ignition, or can control depending on the energy required to initiate initial ignition and complete combustion for fuels with different energy densities and / or ignition characteristics. is there. For example, a hydrogen-based fuel that is easily ignited may require less ignition energy than, for example, diesel fuel that has a higher demand for ignition energy. In such a case, the ignition energy may be provided only by the second force generator 126. However, in embodiments where greater ignition energy is required, the second force generator 126 supplies more energy alone or with a second energy source coupled to the conductor 116 via the voltage supply conductor 131. can do. While examples of hydrogen and diesel fuel have been given, those skilled in the art will appreciate that embodiments of the present invention can be used with many other fuels, including at least hydrogen and / or diesel fuels.

  The injector 100 can also use, in some situations, energy recovered during operation to at least partially assist in fuel injection and ignition. For example, when the first force generator 124 induces the movement of the driver 120, the second force generator 126 causes the first force to be generated when ignition energy is induced in the second force generator 126. Energy is recovered from the generator 124. Further, energy from the second force generator 126 can be used to actuate the piezoelectric element to actuate the valve 118. The injector 100 can further use the energy recovered from the combustion chamber 112 (eg, energy stored in a capacitor) to initiate and / or sustain an ignition event. For example, light energy, pressure energy, thermal energy, acoustic energy, vibration and / or other types of energy can be used to initiate and sustain a fuel ignition event.

  FIG. 2 is a side cross-sectional view of an integrated injector / igniter 200 (referred to as “injector 200”) constructed in accordance with yet another embodiment of the present disclosure. Several features included in the injector 200 of FIG. 2 are substantially similar in structure and function to the corresponding features of the injector 100 described above with respect to FIG. For example, as shown in FIG. 2, the injection device 200 includes a body 202 having a central portion 204, the central portion 204 being between a first or base portion 206 and a second or nozzle portion 208. Extend. The nozzle portion 208 is configured to extend into the injection port of the cylinder head.

  The injector 200 further includes one or more basal assemblies 227 (indicated individually as a first basal assembly 227a and a second basal assembly 227b), which are the base 206 of the injector 200. The fuel is received in the fuel, and the fuel to the nozzle unit 208 is selectively metered, and the ignition energy is supplied to the nozzle unit 208. More particularly, each base assembly 227 includes a force generation assembly 222 configured to provide ignition energy to a corresponding conductor 216 extending through the body 202 in addition to activating a corresponding poppet or base valve 254. Has been. More particularly, the force generator assembly 222 includes at least a first force generator 224 (eg, at least one solenoid winding or piezoelectric element) as well as a second force generator 226 (eg, at least one solenoid winding). Or a piezoelectric element). Similar to the force generation assembly 122 described above with reference to FIG. 1, the force generation assembly 222 of FIG. 2 controls (1) the flow of fuel by opening the chair of the valve assembly, and (2) valve opening operation. At the end, it is configured to generate ignition energy or voltage by heating and / or ionization. In certain embodiments, to achieve both of these functions, the force generation assembly 222 includes a first force generator 224 that is a first or primary solenoid winding and a first solenoid winding that is a secondary solenoid winding. A second force generator 226. The force generation assembly 222 and in particular the secondary solenoid winding 226 can be connected to the conductor 216 via the voltage supply conductor 230. The number of turns of the secondary winding 226 can be larger than that of the first winding 224. Each of the first and secondary windings 224, 226 may also include one or more insulating layers (eg, varnish or other suitable insulator), but the second winding 226 may include more insulating layers than the first winding 224. The force generation assembly 222 can also be electrically connected to the conductor 216. By configuring the force generating assembly 222 as a transformer with a greater number of turns of primary winding 224 and secondary winding 226, the main winding 224 causes a valve pull to actuate the driver or plunger mover. A large current can flow when ignition energy or voltage is applied to cause or induce its movement. Opening the relay to the primary winding 224 releases the driver, and very high ignition energy or voltage is generated by the secondary winding 226. The high ignition energy or voltage of the secondary winding 226 can be utilized for heating and / or plasma generation ignition events, for example by providing initial ionization, after which any suitable source ( The ionization current and fuel injection continue to be supplied to the combustion chamber by the relatively low ignition energy or voltage release of the already charged capacitor (including photovoltaic, electrothermal, energy recovered from the combustion chamber by the piezoelectric generator) Is done.

  As described above, the force generation assembly 222 guides the movement of the driver 220. The force generation assembly 222 can also be operatively connected to a corresponding controller or processor 223 (indicated individually as a first controller 223a, a second controller 223b), thereby, for example, one of the combustion chambers In response to one or more conditions or other engine parameters, force generating assembly 222 is selectively pulsed or actuated selectively. The driver 220 engages a first check or base valve 254 at the base 206. More particularly, the base valve 254 includes one or more stoppers 229 and engages a biasing member 271 (eg, a coil spring or magnet) positioned within a biasing member cavity 219. Then, the base valve 254 is urged toward the closed position as shown in FIG. 2 (for example, in a direction toward the nozzle portion 208). Base valve stopper 229 also engages driver 220, which causes driver 220 to move base valve 254 between an open position and a closed position. The base valve 254 also includes a base valve head or sealing portion 256 that engages a corresponding valve seat 258 in the normally closed position as shown.

  The injector 200 also includes a fuel inlet fitting 238 (shown individually as a first fuel inlet fitting 238a and a second fuel inlet fitting 238b), which is operatively connected to a corresponding base assembly 227. Fuel into each base assembly 227. Within each base assembly 227, when the base valve 254 is in the open position, fuel flows through the force generation assembly 222 and the driver 220 and through the valve head 256. The injector 200 further includes a fuel connection conduit 257 (indicated individually as a first fuel connection conduit 257 a and a second fuel connection conduit 257 b) that directs fuel from the base portion 206 to the intermediate portion 204 of the body 202. To a fuel flow path or path 217 extending through the nozzle portion 208. The fuel flow path 217 extends longitudinally adjacent the core assembly 213 that extends at least partially from the base portion 206 through the body 202 and into the nozzle portion 208. The core assembly 213 includes a core insulator 240 that is coaxially disposed around an ignition member or conductor 216. The core assembly 213 also includes a cylindrical or annular storage member 288 that at least partially defines a fuel flow path 217 having an ignition insulator 240. Core assembly 213 extends through insulator 242 of body 202. The ignition conductor 216 is operatively connected to the ignition terminal 233 and provides ignition energy or voltage (ignition voltage or energy from the force generation assembly 222) to the ignition electrode 284, which may include one or more ignition functions 287. Supply). The ignition electrode 284 is a first electrode that can generate an ignition event with the second electrode 285, which can be a conductive portion at the distal end of the nozzle portion 208, or at the cylinder head port. It can be a suitable proximal portion. The ignition insulator 240 includes a large diameter end 283 in the vicinity of the ignition electrode 284 that has a larger cross-sectional dimension (eg, a larger cross-sectional diameter).

  The large diameter end 283 of the ignition insulator 240 is configured to contact the flow control valve 266 carried by the nozzle unit 208. The flow control valve 266 is a radially expanding valve that is fixed, glued or otherwise connected to the containment member 288 at a position upstream from the large diameter end 283 of the ignition insulator 240. A fixed end 268 is included. For example, the first end 268 can be bonded to the outer surface of the containment member 288 with a suitable adhesive, thermoplastic polymer, thermosetting composition, or other suitable bonding or fastening means. The flow control valve 266 further includes a second deformable or movable end 270 opposite the first fixed end 268. The movable end 270 contacts the large diameter end 283 of the ignition insulator 240 and is at least partially radially opened, expanded, enlarged or otherwise deformed to cause fuel to be injected into the nozzle portion 208 of the injector 200. Configured to be discharged from. More specifically, the storage member 288 includes a plurality of fuel discharge ports 269 adjacent to the movable end 270 of the flow control valve 266.

  In operation, fuel is introduced into the base assembly 227 via the fuel inlet fitting 238. The fuel flows through appropriate passages through the force generation assembly 222 and the driver 220 to the base valve head 256. For example, the driver 220 may include one or more fuel passages that extend adjacent to the outer periphery or diameter of the driver 220, as shown by the dashed lines in FIG. When the force generating assembly 222 (and more particularly the first solenoid winding 224 or piezoelectric element 224) moves the base valve 254 to the open position, causing the base valve head 254 to move away from the valve seat 258, the fuel is It flows through the valve head 256 and into the fuel connection conduit 257. From the fuel connection conduit 257, the compressed fuel flows into the fuel flow path 217. In one embodiment, the pressure of the fuel in the fuel flow path 217 causes the movable end 270 of the flow control valve 266 to open, expand or deform radially outward so that the fuel has a large diameter of the ignition insulator 240. It is sufficient to allow flow through end 283. However, in other embodiments, the movable end 270 of the flow control valve 266 is radially opened at least partially by one or more actuators, drivers, selective biasing members, or other suitable force generators, It can be expanded or otherwise deformed. When the flow control valve 266 selectively discharges fuel from the fuel discharge port 269, the fuel passes through one or more ignition functions 286, which generate an ignition event to ignite the fuel and burn it Can be injected into the chamber.
