    摘要: When a control valve allows communication through a fuel drain channel, fuel flows into an inner control chamber from an outer control chamber through a communication channel and flows out to a fuel tank. The fuel flow through the communication channel generates a differential pressure between inner control pressure and outer control pressure. Thus, an outer differential pressure immediately after an outer valve opening time can be set small, restraining an increase in the unburnt HC content of exhaust gas at low load, which could otherwise result from a high rising speed of an outer needle valve immediately after the outer valve opening time. An inner differential pressure immediately after an inner valve opening time can be set large, restraining an increase in the smoke content of exhaust gas, which could result from a low rising speed of an inner needle valve immediately after the inner valve opening time.

A dual solenoid actuator has a first fuel injection configuration at which the first fuel inlet is fluidly connected to the first set of nozzle outlets, the first armature is at an energized position, the second armature is at the un-energized position and the lever is at the first angular orientation. The dual solenoid actuator has a second fuel injection configuration at which the second fuel inlet is fluidly connected to the second set of nozzle outlets, the first armature is at the un-energized position, the second armature is at an energized position and the lever is at a second angular orientation. The dual solenoid actuator may also include a combined fuel injection configuration.

    摘要: A tubular outer needle 42 is slidably housed in a body 41 such that the outer needle can communicate nozzle and suck chambers R1 and R2 with each other and shut them from each other, and defines the nozzle and suck chambers R1 and R3. A rod-like inner needle 43 is coaxially slidably housed in the outer needle 42, and the tip end portion thereof moves into the suck chamber R2 at its lowermost position. In the range of the small inner lift amount, an annular clearance is formed between an inner peripheral surface of an inner side wall defining the suck chamber R2 and an outer peripheral surface of an outer side wall of the tip end portion of the inner needle 43. Outer and inner lift amounts are regulated such that when the fuel injection is started, the outer and inner lift amounts simultaneously increase from zero while when the fuel injection is terminated, the inner lift amount returns to zero after the outer lift amount returns zero.
