摘要： The fuel injector (44, 66, 70, 74) for an internal combustion engine, particularly of the inwards or outwards opening needle injector type, comprises an injector body (12) which in particular forms a nozzle (16) ending in an injection orifice, means for closing off the said injection orifice of the said injector body, the said closing-off means comprising a vibrating pintle (24) ending in a head (26) for closing off the said injection orifice, return means (30) for returning the said closing-off means to the position in which they close off the said injection orifice, and means (36, 72) for setting the said pintle (24) and/or the said nozzle (16) into cyclic longitudinal vibration so as to open and close the injection orifice alternately. The fuel injector (44, 66, 70, 74) is notable in that it comprises selectively activatable means (46, 48) for immobilizing the said pintle (24) with respect to the said body (12).

摘要： The invention concerns a fuel injection device for internal combustion engine. The fuel injection device for internal combustion engine comprises an injecting head integral with the end of a needle (3) mobile in translation inside an injection housing (4) supplied with high pressure fuel and having a seat for the injecting head, and a piezoelectric or magnetoresistive vibratory element (5) capable, when it is energized, to act on the needle (3), maintained by a return spring (10), to cause same to vibrate, such that the injecting head co-operates with its seat to periodically open and close a passage for fuel injection. The device comprises means for controlling (16, 17) the movement of the needle in translation, countering the return spring (10), independent of the vibratory element (5).

摘要： A fuel injector (10) performs main fuel injection by raising fuel pressure in a nozzle chamber (30) to lift a check valve member (26) to a fully open position, and performs preinjection or microinjection by operating a solid state motor (22) to lower a check stop (52) so that when fuel pressure in the nozzle chamber (30) is raised the check valve member (26) is limited to lift a much smaller distance.

摘要： The invention relates to a fuel injection valve which comprises a housing (1) with a valve seat (20) configured therein and an interior valve needle (17) and an exterior valve needle (15). The pressure in an exterior control chamber (56) exerts a closing force onto the exterior valve needle (17) and the pressure in an interior control chamber (54) exerts a corresponding closing force onto the interior valve needle (15). The interior control chamber (54) is linked with a control valve chamber (60) of a control valve (30) via an interior outlet throttle (51) and the exterior control chamber (56) via an exterior outlet throttle (49), a valve member (62) being disposed in said control valve chamber (60). The interior control chamber (54) is linked with a high-pressure area (8) via an interior inlet throttle (47) and the exterior control chamber (56) via an exterior inlet throttle (45). The valve member (62) can assume a first, a second and a third switched position so that the pressure in the control chambers (54; 56) can be controlled to open only the exterior valve needle (17) as well as both valve needles (15; 17).

摘要： An injection rate shaping nozzle assembly (52) for a fuel injector is provided which includes a closed nozzle valve element (66) and a rate shaping control device (82) including an injection spill circuit for spilling a portion of the fuel to be injected to produce a predetermined time varying change in the flow rate of fuel injected into a combustion chamber. The spill circuit includes a spill passage (88) integrally formed in the nozzle valve element (66). The rate shaping control means (82) may include a spill valve (86) for controlling the spill flow through the spill circuit to create a low injection flow rate followed by a high injection flow rate. The spill passage (88) may communicate with the injector nozzle cavity (58) between injection events or alternatively may be blocked to prevent spill flow between injection events. The rate shaping control device (82) may include a spill accelerating device in the form of a spill chamber formed in the nozzle valve element (66) for creating a rapid increase in the spill flow rate.
