摘要： An electronically controlled fuel injection valve can control the time to inject fuel and the amount of fuel to be injected in response to a control signal independently from the operating condition of an engine unlike a traditional mechanical fuel injection valve. The electronically controlled fuel injection valve employs a control method for fuel injection that increases the force of lifting up a cutoff needle of an injection controller by delivering high-pressure fuel to a lower pressure chamber via a control needle, thereby rapidly controlling fuel injection, has a simple structure making it easy to assemble, replace and precisely machine parts, and has a simple flow path structure which facilitates fabrication.

摘要： Disclosed is a fuel injection valve (4) comprising a control member (70) that is provided with a control passageway (114) which is arranged eccentrically relative to the housing axis (8) and can be opened and closed by a closure piece (96) with the aid of an actuator assembly (26) in order to obtain intermittent injections. The control member (70) is positioned by means of a centering pin (124) in order to define the circumferential position of the eccentric control passageway (114). The centering pin (124) is guided within a pocket bore of the control member (70) as well as within a bore of an intermediate plate (12), a cylindrical element (13), or a spacing sleeve (202). The actuator assembly (26) is designed as an electromagnetic actuator (80) in which the stop (98; 99) for limiting the lift of the pilot valve member is designed as a monolithic component of the intermediate plate (12) or as a flat stop disk (97) in a separate workpiece. The eccentric position of the actuator assembly (26) and the design of the stop (98; 99) allow for a very compact design of the fuel injection valve. The compact design makes it possible to mount a suitable storage chamber in the monolithic housing body (10) of the fuel injection valve, above the high-pressure inlet bore (20).

摘要： An engine having improved combustion characteristics is provided. The engine includes a fuel injection system that is variable between two operational states. In the first operating state, the fuel injectors provide a fuel spray having first spray pattern characteristics. When the system detects that an operation characteristic exceeds a threshold, the fuel injectors are displaced into a second operating state. In the second operating state, the fuel injectors provide a spray pattern having first spray pattern characteristics. The combustion cycle may be characterized by timing the fuel injection so that the fuel is sprayed into the cylinder early in the compression stroke. Further still, the combustion cycle may be characterized by controlling the fuel pressure so that the fuel pressure is inversely related to the load on the engine.

摘要： A relatively inexpensive robust attachment strategy that insures good perpendicularity between a valve member and an armature utilizes an intervening nut between the armature and valve member. A valve member is received in a guide bore of a valve body. A nut is threaded onto one end of a valve member. The armature is press fit onto a orientation neutral interface of the nut, and a fixture is utilized to set near perfect perpendicularity between an air gap plane of the armature and a centerline of the valve member. The armature is then welded to the valve member. The weld may be accomplished via laser welding while the valve assembly is firmly held in an appropriate position within the fixture. The valve assembly may be then incorporated into a fuel injector stack of components in a conventional manner.

摘要： A fuel injection system includes a fuel injector that includes a nozzle assembly and at least one passageway that includes at least one fluid oscillator. The at least one passageway extends from a nozzle orifice, positioned on the outside of the fuel injector, to inside the fuel injector. Fuel from inside the fuel injector moves through the at least one fluid oscillator and oscillates between a high injection rate and a low injection rate as it moves through the at least one nozzle orifice and into the combustion chamber.
