摘要： In the DME fuel supply device for a diesel engine, the time necessary to retrieve DME fuel remaining in the injection system after stopping the diesel engine into the fuel tank can be reduced. In a non-injection state, a three-way valve (71) is controlled to be OFF to form a communication passage in the direction indicated by the arrow B and a two-way valve (72) is controlled to be ON. DME fuel delivered from a feed pump (5) is delivered to an aspirator (7), passed from an inlet (7a) to the outlet (7b) thereof and returned to a fuel tank (4). That is, the DME fuel circulates via the aspirator. A vapor-phase pressure delivery pipe switching solenoid valve (75) is controlled to be ON and opened so that flow can pass through a vapor-phase pressure delivery pipe (73) connecting the vapor-phase (4a) in the fuel tank (4) and the inlet of the fuel gallery (11). DME fuel in a liquid state remaining in the fuel gallery (11), an overflow fuel pipes (8) and (9) is delivered under pressure to a suction port (7c) by the high pressure of the vapor-phase (4a).

摘要： In an injection pump element 2, a communication route for communicating an injection pipe 3 connected to a fuel liquid outlet 212 and an inner peripheral surface of a plunger barrel 25 is formed by a purge passage 242 formed in a delivery valve seat 24, a purge passage 252 formed in the plunger barrel 25, and a purge port 253. When the injection pump element 2 is in a non-injection state, the plunger 26 is rotated circumferentially to such a rotational position that a purge groove 265 formed in an outer peripheral surface of the plunger 26 and a purge port 253 formed in an inner peripheral surface of the plunger barrel 25 are communicated to each other. The purge groove 265 is communicated to a fuel gallery 11 via a hole 263 and a notch 262. When the injection pump element 2 is in the non-injection state, the injection pipe 3 is communicated to the fuel gallery 11 even if the delivery valve 23 is closed.

摘要： The fuel injection nozzle according to the present invention comprises a nozzle body provided with nozzle holes, a needle valve that opens and closes the nozzle holes, an armature that is mechanically linked with the needle valve and a stator that faces opposite the armature, so that, by displacing the stator with a micromotor, the lift quantity of the needle valve can be adjusted. In addition, a cover member that rotates slidably around the circumference of the nozzle body is provided and by causing this cover member to rotate with a micromotor, the opening area of the nozzle hole contributing to injection is varied. With these structural features, it becomes possible to intentionally achieve a desired injection pattern.

摘要： A plurality of injection holes are circumferentially arranged in the peripheral wall of the hole at predetermined intervals and at axially different circumferential levels in the leading end portion of the nozzle body to introduce pressurized fuel, and the injection holes at each circumferential level are set different in diameter. On the other hand, a rotary valve has a plurality of fuel guide holes each corresponding to the injection holes at the respective circumferential levels. The fuel guide holes of the rotary valve and the injection holes of the nozzle body are arranged in such a relationship that while the fuel guide holes at one or more than one circumferential level are each made to communicate with the fuel guide holes at one or more than one corresponding circumferential level, the fuel guide holes at the other circumferential levels are not allowed to communicate with any injection holes.

摘要： A nozzle is provided wherein the operation of injection hole groups is switched from one to another in accordance with the axial displacement of a spool valve. A nozzle body has a bottomed hole, and a plurality of injection hole groups are provided at different circumferential levels in the side wall of the bottomed hole, the injection holes at different circumferential levels being different in diameter from each other. The valve portion of the spool valve is urged by a spring so that the lower end of the valve portion abuts against the base of the bottomed hole in the normal condition. Moreover, a fuel passage communicates with one of the injection hole groups in the normal condition and communicates with the other injection hole group at a position where the valve portion is displaced axially against the spring force on receiving the pressure of pressurized fuel. In addition, braking means is used to fixedly hold both the axial positions of the spool valve, depending on the operating condition of an engine.
