Abstract: Engineers have determined that the performance of fuel injectors, including those used in common rail fuel injection systems, can be increased, and undesirable emissions reduced, by controlling the mass flow rate of fuel injected into a combustion chamber during an injection event. While a number of fuel injectors have been developed that have limited rate shaping capabilities, the ability to produce some front end rate shapes has not been possible. In an effort to increase rate shaping capabilities, the present invention includes a valve assembly having at least one valve member that is movable between a plurality of positions to control fluid communication between a number of fluid inlets and outlets.

Abstract: The invention relates to a unit injector system for supplying the combustion chamber of a self-igniting internal combustion engine with fuel. The unit injector system has a high-pressure chamber that can be subjected to pressure via a pump piston. A storage piston is received inside a storage chamber and is acted upon via a compression spring disposed in a spring holder. A return flow throttle element, which delays the buildup of pressure in the storage chamber, is disposed between the high pressure chamber and the storage chamber of the storage piston.

Abstract: The fuel injection system has one high-pressure fuel pump and one fuel injection valve for one cylinder of the engine. The fuel pump has a work chamber, and the injection valve has a valve member, and which is movable in an opening direction, counter to the force of a closing spring, by the pressure in a pressure chamber communicating with the pump work chamber; the closing spring is braced between the injection valve member and a displaceable deflection piston which, defines a prechamber that communicates with the pump work chamber. The deflection piston is movable into a storage chamber counter to the force of the closing spring. The prechamber communicates with the pump work chamber via a first throttle restriction, and the pressure chamber of the fuel injection valve communicates with the pump work chamber via a second throttle restriction, circumventing the prechamber.

Abstract: The fuel injection device has a fuel injection valve that has an injection valve member, which is guided so that it can slide in a valve body and controls at least one injection opening and which can be moved in the opening direction, counter to the force of a closing spring contained in a spring chamber by means of the pressure prevailing in a pressure chamber of the fuel injection valve. Highly pressurized fuel is supplied from a high pressure source to the pressure chamber of the fuel injection valve. An electrically controlled valve at least indirectly controls a connection of the pressure chamber to a relief chamber and connects the pressure chamber to the relief chamber in order to terminate the fuel injection. The pressure chamber of the fuel injection valve has a connection to the spring chamber, which connection contains a check valve that opens toward the pressure chamber.

Abstract: A unit injector assembly is provided that helps to ensure maximum injection flow while minimizing the harmful affects of pressure waves within the unit injector assembly. The unit injector assembly has a first fuel passageway extending from the plunger piston pumping chamber to the tip check stem injection chamber and valve seat. The unit injector assembly has a second fuel passageway extending from the tip check stem injection chamber to a fuel control valve assembly. A flow restricting fuel passageway connects one of the pumping chamber and the first fuel passageway with the second fuel passageway and acts to minimize cavitation at the valve seat and effectively eliminates pressure waves within the unit injector assembly.

Abstract: The fuel injection system has a high-pressure fuel pump (10) and a fuel injection valve (12) connected to it for each cylinder of the internal combustion engine. A pump piston (18) of the high-pressure fuel pump (10) delimits a pump working chamber (22) that is connected to a pressure chamber (40) of the fuel injection valve (12), which has an injection valve element (28) that controls injection openings (32) and can be moved in an opening direction (29) counter to a closing force by the pressure prevailing in the pressure chamber (40). A first control valve (68) controls a connection (66) of the pump working chamber (22) to a relief chamber (24) and a second control valve (70) controls a connection (64) of a control pressure chamber (52), which communicates with the pump working chamber (22), to a relief chamber (24). A throttle restriction (63, 65) is respectively provided in connections (62, 64) of the control pressure chamber (52) to the pump working chamber (22) and the relief chamber (24). An additional pressure chamber (54) is provided, which is connected to the pump working chamber (22) and is delimited by a pressure surface (53) that is used to exert an additional force on the injection valve element (28) in the closing direction.

Abstract: The fuel injection system has a fuel injection valve (12) with an injection valve member (34), by which at least one injection opening (36) is controlled, and the injection valve member (34) is acted upon by the pressure prevailing in a pressure chamber (44) of the fuel injection valve (12) and is movable by this pressure, counter to the force of a closing spring (48) disposed in a spring chamber (50), in an opening direction to open the at least one injection opening (36), and fuel is delivered under high pressure to the pressure chamber (44) by a high-pressure fuel pump (10) for a fuel injection. The injection valve member (34) is urged in the closing direction at least indirectly by the pressure prevailing in a spring chamber (50) of the fuel injection valve (12). The pressure in the spring chamber (50) is variable; the spring chamber (50) has a communication with a pressure source (66; 20), which is controlled by a valve (67). Thus different opening pressures of the fuel injection valve (12) for a preinjection and a main injection of fuel can be attained.
