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.

摘要： An engine (10) includes an electronically controlled mixing ratio control valve (24) with a first inlet (25) fluidly connected to a source of gasoline (20), and a second inlet (26) fluidly connected to a source of compression ignition fuel (22), such as distillate diesel fuel. An outlet (42) from the mixing ratio control valve (24) is fluidly connected to a fuel inlet (40) of at least one fuel injector (17). The mixing ratio control valve (24) varies a mixture ratio of gasoline to compression ignition fuel responsive to a control signal communicated from an electronic controller (18). The blended fuel may be pressurized to injection levels in the fuel injector (17), and injected directly into the engine (10) cylinder (12). The compression ignition fuel is compression ignited, which in turn ignites the gasoline to produce a lower and better combination of undesirable emissions as a result of the combustion process.
