Fuel injection device and internal combustion engine

摘要: PROBLEM TO BE SOLVED: To generate optimal driving force to an operating condition of injector by providing with coils whose time change ratios magnetomotive are different from each other, and applying voltages which other the coils. SOLUTION: Fuel pressurized a fuel pump is supplied 10, passage opened/closed between ball valve for composing element seat surface formed on nozzle side, injection rate hole 5 downstream 4 controlled. For 16, control coil 11 hold 12 disposed 10. The have electric characteristics other. It thus possible so as inject in good condition.
