摘要： Fuel injectors are disclosed that are capable of simultaneously delivering liquid and gaseous fuels to the combustion chamber of a compression ignition engine. For example, fuel injectors are disclosed that can deliver liquid diesel fuel, as a pilot liquid, along with a gaseous fuel, such as natural gas or other available fuels that are gases at atmospheric pressure and ambient temperature. The fuels are delivered to the needle control valve cavity sequentially via separate passageways. The delivery of the pressurized liquid fuel is actuated by the single actuator that is provided for each fuel injector. The actuator may be of a solenoid type or of a piezoelectric type or other suitable actuator as will be apparent to those skilled in the art. A liquid fuel check valve, in combination with the actuator, controls the delivery of the pilot liquid fuel to the needle control valve cavity.

摘要： A fuel injector includes first and second check valve members that open and close first and second nozzle outlet sets, respectively, to inject two fuels that differ in at least one of chemical identity, pressure and molecular state. The first check valve member defines a through passage, includes a closing hydraulic surface exposed to fluid pressure in the first control chamber, and moves into and out of contact with a first seat on an injector body. The second check valve member includes a closing hydraulic surface exposed to fluid pressure in a second control chamber, and moves into and out of contact with a second seat located on the first check valve member. A control valve member is movable between first and second positions that respectively block and allow fluid communication between the first and second control chambers and a drain outlet.

摘要： Various fuel injection systems and fuel injectors are disclosed that provide varying cooling rates for fuel injectors connected in series to fuel supply and drain rail. The local cooling rate for each injector is manipulated to balance the heat flux or heat transfer across the injectors disposed along the rail. The cooling rates may be manipulated by varying sizes of openings or slots in the nozzle case, by varying annular spaces disposed between the nozzle case and the portion of the injector body that houses the actuator and solenoid assembly, and by varying the size of annular spaces disposed between the nozzle case and the cylinder head. Strategic placement of slots in the nozzle case that direct more flow at the portion of the injector body that houses the actuator and solenoid assembly may also be employed. As a result, the operating temperatures of fuel injectors connected in series to a fuel rail can be manipulated and moderated so the downstream injectors are not prone to overheating.

摘要： Common rail fuel injectors typically have difficulty in changing an injection rate during an injection event. Fuel injectors for this common rail fuel injection system include a multi-position admission valve. The admission valve is stoppable at a middle position to inject fuel at a low rate. The lower rate is accomplished by leaking some fuel to drain to reduce injection pressure. The admission valve is also stoppable at a fully open position to inject fuel at a high rate. Fuel injection events are ended, and the fuel injectors maintained between injection events, with the admission valve member in contact with a supply seat to close the high pressure supply passage. This strategy can be used in conjunction with a spring-biased needle valve member to expand fuel injector capabilities.
