Patent number: 6871630Abstract: A fuel injector-spark plug combination comprises a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine and a spark plug with a spark-plug insulator, a first electrode and a second electrode for igniting the fuel injected into the combustion chamber. The fuel injector includes an actuator cooperating with an actuation device, which is in force-locking, operative connection to a valve needle, the valve needle, or a valve-closure member connected thereto, cooperating with a valve-seat surface to form a sealing seat. The valve needle of the fuel injector and the spark-plug insulator of the spark plug are positioned in a shared housing at a biaxial offset.Type: GrantFiled: September 20, 2002Date of Patent: March 29, 2005Assignee: Robert Bosch GmbHInventors: Werner Herden, Dieter Volz, Gernot Wuerfel, Anja Melsheimer, Simon Schmittinger, Rainer Norgauer, Rene Deponte

Patent number: 6659084Abstract: The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber in that a control part closes and opens inlet bores for fuel that is at high pressure. The control part is actuatable by means of a hydraulic-mechanical booster. The pump part, valve part and nozzle part of the fuel injection apparatus are disposed in a vertical arrangement, hydraulically in line with on another in terms of the fuel flow.Type: GrantFiled: April 26, 2002Date of Patent: December 9, 2003Assignee: Robert Bosch GmbHInventors: Anja Melsheimer, Matthias Beck, Manfred Mack

Patent number: 6644280Abstract: The invention relates to a method for injecting fuel, which is at high pressure, into air-compressing internal combustion engines employing an injection system which includes a compressor unit for compressing fuel and containing an actuating device for control valves with which device the nozzle needle of an injector is controlled. One of the two control valves is triggered multiple times or in clocked fashion via a piezoelectric actuator during individual injection phases or during the injection cycle.Type: GrantFiled: October 15, 2001Date of Patent: November 11, 2003Assignee: Robert Bosch GmbHInventors: Nestor Rodriguez-Amaya, Anja Melsheimer, Volker Reusing, Volker Leifert

Publication number: 20030019479Abstract: The invention relates to an apparatus for injecting fuel, having a control valve (16) that has a valve chamber (18). From the valve chamber (18), a high-pressure line (37) leads to the injector; the valve chamber (18) also communicates with a pump chamber (23) for fuel that is at high pressure. The control part of the control valve (16) is actuatable by means of an electromagnet (17). The control valve (16) is coupled with a passive piston (20), which to avoid the pulse change, which acts on the piston (20), is provided with a bore (21).Type: ApplicationFiled: August 7, 2002Publication date: January 30, 2003Inventors: Anja Melsheimer, Gerd Wille

Publication number: 20020190135Abstract: The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve (14) that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber (6.1), in that a control part (6) closes and opens inlet bores (5, 8) for fuel that is at high pressure. The control part (6) is actuatable by means of a hydraulic-mechanical booster (18, 19, 20, 21). The pump part (P), valve part (V) and nozzle part (D) of the fuel injection apparatus (1) are disposed in a vertical arrangement, hydraulically in line with one another in terms of the fuel flow.Type: ApplicationFiled: April 26, 2002Publication date: December 19, 2002Inventors: Anja Melsheimer, Matthias Beck, Manfred Mack

Publication number: 20020092507Abstract: An apparatus for controlling the injection sequence in fuel injection systems having an injection nozzle that can be acted upon via a control valve which, in turn can be acted upon with fuel from a pump chamber. The control valve is actuatable by means of an electromagnet that varies the magnet valve stroke length. Via the magnet valve stroke length, the fuel supply line into a nozzle chamber of the injection nozzle is opened and closed. The control part of the control valve functions as a throttle element in a hollow chamber provided on the low-pressure side.Type: ApplicationFiled: November 28, 2001Publication date: July 18, 2002Applicant: Robert Bosch GmbHInventors: Roger Potschin, Anja Melsheimer, Michael Heinzelmann
