摘要： A gaseous fuel internal combustion engine (10) includes an engine housing (12) defining at least one cylinder (14), and an intake housing (18) defining an intake passage (20) fluidly connecting with the at least one cylinder (14). The engine (10) includes a gaseous fuel delivery mechanism (13) coupled with the engine housing (12) and a distributed ignition promoting mechanism (22) having a bead presentation device (24) extending into the intake passage (20) and configured to present a liquid bead of distributed ignition promoting material (100) therein such as engine lubricating oil. During operation, gases passing through the intake passage (20) dislodge the liquid bead from the bead presentation device (22) and carry the distributed ignition promoting material (100) into the cylinder (14) for distributively igniting therein a mixture containing a gaseous fuel, air and the distributed ignition promoting material (100).

摘要： A dual fuel injector (100) may be used to inject both gas and liquid fuel into a cylinder (7) of a compression ignition engine (5). An injector body (12) defines a first set of nozzle outlets (90), a second set of nozzle outlets (90), a first fuel inlet (33) and a second fuel inlet (36). A dual solenoid actuator (100) includes a first armature (110), a first coil (102), a second armature (103) and a second coil (104) that share a common centerline (54). The dual solenoid actuator (100) has a non-injection configuration at which the first armature (110) is at an un-energized position and the second armature (103) is at an un-energized position. The dual solenoid actuator (100) has a first fuel injection configuration at which the first fuel inlet (48) is fluidly connected to the first set of nozzle outlets (90), the first armature (110) is at an energized position and the second armature (103) is at the un-energized position. The dual solenoid actuator (100) has a second fuel injection configuration at which the second fuel inlet (57) is fluidly connected to the second set of nozzle outlets (96), the first armature (110) is at the un-energized position and the second armature (103) is at an energized position. The dual solenoid actuator (100) may also include a combined fuel injection configuration.
