摘要： The present disclosure is directed to a fuel circuit of a fuel injector that includes a first channel, a second channel, and a valve. The first channel is configured to receive a first fuel and define a flow path for the first fuel. The second channel is configured to receive a second fuel and define a flow path for the second fuel. The valve is in fluid communication with the first channel and the second channel. The valve is adapted to direct the second fuel to the first channel when a pressure in the first channel reaches a predetermined level.

摘要： A fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet, and has disposed therein a nozzle chamber, a needle control chamber and a valve chamber. The needle control chamber is fluidly connected to the drain outlet through a drain passage that includes the conical seat, is fluidly connected to the nozzle chamber through a Z orifice, and fluidly connected to the valve chamber through an A orifice. The nozzle chamber is fluidly connected to the valve chamber by a pressure passage that includes an F orifice that opens through a flat seat. A control valve member is trapped to move between contact with conical seat and contact with the flat seat. An electrical actuator is operable to push the control valve member away from the conical seat toward the flat seat when energized. A direct control needle valve has an opening hydraulic surface positioned in the nozzle chamber and a closing hydraulic surface positioned in the needle control chamber. The fuel injector may include first and second electronically controlled valves for independently injecting a gaseous fuel and a liquid fuel.

摘要： A hydraulically actuated fuel injector includes an injector body having a nozzle chamber that opens to a nozzle outlet. A control valve is mounted in the injector body and is attached to a solenoid that is moveable between a rest position and a fully energized position. A piston/plunger/barrel assembly is utilized to hydraulically pressurize fuel in the nozzle chamber to a fuel pressure that is substantially proportional to an amount of current being supplied to the solenoid. A needle valve member is positioned in the nozzle chamber and moveable between an open position in which the nozzle outlet is opened and a closed position in which the nozzle outlet is blocked. Finally, a spring is utilized to bias the solenoid toward its rest position.
