Patent number: 6802295Abstract: An air intake shutoff device is disclosed for an engine. The device includes at least two air shutoff valve assemblies. Each of these assemblies has a gate for controlling air flow into the engine. A linkage couples together the gates of each of the air shutoff valve assemblies such that closing of one gate of the at least two air shutoff valve assemblies effectuates closing of all other gates of the at least two air shutoff valve assemblies.Type: GrantFiled: December 20, 2002Date of Patent: October 12, 2004Assignee: Caterpillar IncInventors: Matthew Ross Bedwell, Jeffrey Yeager

Patent number: 6802296Abstract: A fuel injection system for internal combustion engines includes a fuel injector that includes a spray-orifice plate through which fuel is injected into a combustion chamber. The combustion chamber is bounded by a cylinder wall. A piston is guided in the cylinder wall, and a spark plug projects into the combustion chamber. The diameters of injection orifices positioned on the spray-orifice disk are distributed such that, at a particular point of injection, the injected fuel is distributed as homogenously as possible in an injection volume of the combustion chamber, bounded by the piston and the cylinder wall.Type: GrantFiled: June 11, 2003Date of Patent: October 12, 2004Assignee: Robert Bosch GmbHInventors: Stefan Arndt, Werner Herden

Patent number: 6802297Abstract: A fuel rail damper, which includes a hollow member having a first end and a second end, and at least one active portion. The hollow member being open to atmospheric pressure, thereby defining a chamber in conjunction with the at least one active portion.Type: GrantFiled: January 27, 2003Date of Patent: October 12, 2004Assignee: Delphi Technologies, Inc.Inventors: Charles W. Braun, Jay K. Sofianek

Patent number: 6802298Abstract: A nozzle needle of a fuel injector is driven in a controlled manner by changing back pressure applied thereto. The back pressure is controlled by a pressure control valve driven by stacked piezoelectric elements. A valve body of the pressure control valve is disposed in a valve chamber having a drain port and a high pressure port which are selectively closed. A diameter D1 of a drain seat, a diameter D2 of a high pressure seat, and a diameter D3 of a piston portion connected to the valve body are set to satisfy a relation: D1≧D2≧D3. In this manner, operation of the pressure control valve is stabilized, and thereby the fuel injector is smoothly and stably operated.Type: GrantFiled: December 15, 2003Date of Patent: October 12, 2004Assignee: Denso CorporationInventors: Tetsuya Yoshimura, Shuichi Matsumoto

Patent number: 6802299Abstract: A control system and a control method for an internal combustion engine have a cylinder including an intake valve and an exhaust valve with a fully variable valve-gear assembly. An engine control unit determines setpoint values with regard to a fresh gas charge, an internal residual gas charge, a torque reduction, an EGR control strategy, and a charging strategy. In addition, a transmission device is provided which transmits setpoint values determined by the engine control unit to a valve control unit in synchronization with the crankshaft angle. The valve control unit controls the fully variable valve-gear assembly of the intake and exhaust valve of the cylinder of the internal combustion engine on the basis of the setpoint values determined by the engine control unit.Type: GrantFiled: May 27, 2003Date of Patent: October 12, 2004Assignee: Robert Bosch GmbHInventors: Karsten Mischker, Rainer Walter, Bernd Rosenau, Udo Diehl, Hermann Gaessler, Juergen Schiemann, Christian Grosse, Georg Mallebrein, Volker Beuche, Stefan Reimer

Patent number: 6802300Abstract: A lift-controlled valve as a fuel metering device of an injection system for internal combustion engines has a valve needle which may be actuated axially against the resistance of a spring, the valve needle being situated in a graduated coaxial recess in a valve body and interacting with a valve seat formed in the recess of the valve body in this case controlling the fuel injection process; the valve has in addition a high-pressure area which is connected to an assigned injection nozzle and which is located upstream from the valve seat, a low-pressure area which is located downstream from the valve seat and which opens out into a fuel return flow, and a low-pressure equalizing piston which coaxially adjoins the valve and which is fixedly connected to the valve needle.Type: GrantFiled: December 6, 2002Date of Patent: October 12, 2004Assignee: Robert Bosch GmbHInventor: Andreas Dutt

Patent number: 6802301Abstract: The invention relates to a fuel supply system for an internal combustion engine, having a unit such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.Type: GrantFiled: May 8, 2002Date of Patent: October 12, 2004Assignee: Robert Bosch GmbHInventors: Edwin Fauser, Stephan Kleppner, Kurt Frank, Hans-Peter Braun, Wolfgang Bueser, Klaus-Dieter Hufnagel, Willi Strohl, Jochen Rose, Wolfgang Hiller, Erich Eiler, Frantisek Buric, Jaroslav Moucka

Patent number: 6802302Abstract: A system is disclosed for diagnosing EGR flow rate operation in an internal combustion engine includes an intake manifold and an exhaust manifold coupled to the engine and an EGR conduit for recirculating exhaust gas from the exhaust manifold to the intake manifold. Means are provided for determining an EGR fraction corresponding to a fractional amount of recirculated exhaust gas in a total air charge supplied to the intake manifold. A control computer is configured to continually accumulate at least one EGR fraction error sum as a function of the EGR fraction and a desired EGR fraction, and to diagnose EGR flow rate operation as a function of the accumulated value of the at least one EGR fraction error sum.Type: GrantFiled: April 8, 2003Date of Patent: October 12, 2004Assignee: Cummins, Inc.Inventors: Xiaoqiu Li, Mark R. Stepper, Stephanie L. Goerges, Yue Yun Wang
