Patent number: 6053153Abstract: An internal combustion engine for motor vehicles, with an intake tube for aspirating combustion air, in which the tube leads to at least one combustion cylinder, and in which tube a throttle valve is disposed. The intake tube effects a mixing of combustion air and fuel vapor downstream of the throttle valve. For the sake of intensive mixing of fuel vapor and combustion air into a largely homogeneous mixture, the fuel vapor generated in a fuel evaporator outside the intake tube is introduced via a delivery device into air turbulence paths that unavoidably develop downstream of the throttle valve in the intake tube as a consequence of the geometry of the intake tube and/or throttle valve.Type: GrantFiled: November 6, 1998Date of Patent: April 25, 2000Assignee: Robert Bosch GmbHInventors: Winfried Moser, Klaus Joos, Anwar Abidin, Georg Mallebrein, Jorg Lange, Andreas Eichendorf, Christof Vogel, Gerhard Benz, Nikolaus Simon

Patent number: 6050507Abstract: The orifice plate has a complete fluid passageway including inlet orifices, outlet orifices and at least one channel (cavity) disposed between them. The at least three functional levels of the orifice plate, having in each case a characteristic orifice structure, are constructed one on top of the other through electrodeposition (multi-layer electroplating), so the orifice plate is embodied in one piece. Because the orifice plate should be hydraulically unthrottled if the available plate surface is small, the inlet orifices are created with the largest possible circumferences. The orifice plate is particularly suited for use at injection valves, in paint nozzles, inhalers or ink-jet printers, in freeze-drying methods, for spraying or injecting fluids, or for atomizing medications.Type: GrantFiled: May 21, 1998Date of Patent: April 18, 2000Assignee: Robert Bosch GmbHInventors: Volker Holzgrefe, Stefan Arndt, Nikolaus Simon, Frank Schatz, Heinz Fuchs, Gunter Dantes, Detlef Nowak, Jorg Heyse, Beate Ader

Patent number: 5175505Abstract: A capacitive sensor includes a plurality of individual condenser elements, each of which consist of a first, preferably circular, electrode and a second, preferably surrounding ring-shaped, electrode, which are mounted on one side of a nonconducting support. A common conductor is connected to each of the first electrodes of condenser elements. A signal can be detected separately from each of the condenser elements via conductors connected separately to the individual second electrodes. To increase the sensitivity and to avoid interference, the remote side of the support opposite to the one side is provided with a third additional electrode, which is at ground potential and also acts as a shield for interfering couplings. The sensor is used for measurement of the fuel film thickness in the intake of an internal combustion engine.Type: GrantFiled: September 26, 1991Date of Patent: December 29, 1992Assignee: Robert Bosch GmbHInventors: Horst Magenau, Nikolaus Simon, Heins-Erdam Bollhagen, Siegbert Steinlechner, Berthold Wocher

Patent number: 5012981Abstract: The invention relates to an injection valve for internal combustion engine fuel injection systems. The valve is designed to inject fuel into the intake manifold. The valve comprises a valve housing containing a core, with which an armature cooperates. A nozzle body with a valve seat is connected to the valve housing. A sealing seat of a valve needle guided in the nozzle body cooperates with the valve seat. The valve needle is guided by first and second guide parts in a guide bore of the nozzle body and the second guide part, which is adjacent to the sealing seat in the upstream direction, is provided with metering bores. These metering bores are inclined such that they produce a spinning effect when the valve is open, thereby providing for good preparation of the fuel. According to the invention, each metering bore discharges immediately proximate to and directly upstream of, the sealing seat.Type: GrantFiled: August 23, 1990Date of Patent: May 7, 1991Assignee: Robert Bosch GmbHInventors: Volker Holzgrefe, Nikolaus Simon, Ewald Ziegler

Patent number: 5005548Abstract: A fuel injection pump is proposed in which over a first portion of the supply stroke of the pump piston fuel for the main injection is pumped via a distributor line and a distributor groove into one at a time of a plurality of fuel injection lines. In a second, remaining portion of the pump piston supply stroke, on the same cam flank, fuel is then pre-stored in a reservoir, controlled by a first electrically controlled valve and a second electrically controlled valve and by one of a plurality of longitudinal control grooves, which fuel subsequently, before the beginning of the next main injection determined by the closure of the first electrically controlled valve, is pumped via a second distributor line into the next succeeding injection line.Type: GrantFiled: June 22, 1990Date of Patent: April 9, 1991Assignee: Robert Bosch GmbHInventors: Helmut Rembold, Hannes Pflug, Wilhelm Christ, Hans-Joachim Siebert, Ewald Eblen, Rodriguez-Amaya, Helmut Laufer, Alfred Schmitt, Werner Pape, Dominique Buisson, Pierre Lauvin, Detlev Potz, Nikolaus Simon, Jean Pigeroulet, Anton Karle

Patent number: 4945877Abstract: The fuel injection valve according to the invention enables an improvement in the fuel preparation and hence a more uniform fuel-air mixture while simultaneously supplying different inlet valves of an engine from one fuel injection valve. Downstream of the valve seat face of the fuel injection valve, the fuel enters a central opening from which tangential conduits lead to at least two swirl chambers disposedly spaced apart from one another and which discharge into these chambers at a tangent. From the center of each swirl chamber, which may be embodied in an attachment, a respective metering opening leads to the outside, by way of which fuel can be injected, well prepared, in the form of cone-shaped fuel streams. The fuel injection valve is suitable either for supplying individual inlet valves with a plurality of fuel streams, or for supplying different inlet valves of the engine with fuel at the same time.Type: GrantFiled: March 1, 1989Date of Patent: August 7, 1990Assignee: Robert Bosch GmbHInventors: Ewald Ziegler, Joerg Widera, Stefan Arndt, Nikolaus Simon

Patent number: 4653455Abstract: The injection pump has a pump piston driven with a constant stroke which pumps fuel at injection pressure to an injection nozzle so long as an electrically actuated overflow valve blocks the flow of the fuel overflowing via an overflow conduit to a low-pressure chamber. The overflow valve is a needle valve, the valve needle of which, opening inward toward a pressure chamber that can be placed under injection pressure, by means of a conical closing surface radially defining a needle tip controls a valve seat that widens conically toward the pressure chamber. The cone angle of the closing surface is larger than the cone angle of the associated valve seat and the closing surface forms a sealing edge, the diameter of which is equal to or only slightly smaller than the guide diameter of the guide shank on the valve member.Type: GrantFiled: September 13, 1985Date of Patent: March 31, 1987Assignee: Robert Bosch GmbHInventors: Ewald Eblen, Karl Hofmann, Volker Holzgrefe, Jean Pigeroulet, Nestor Rodriguez-Amaya, Nikolaus Simon, Dietrich Trachte, Friedrich Weiss, Ewald Ziegler

Patent number: 4489701Abstract: A method and a fuel supply system for supplying fuel to a mixture-compressing internal combustion engine with externally supplied ignition. The fuel supply system includes a nozzle having a flow cross section of a nozzle-like body which discharges into the intake tube. Compressed air furnished by a compressed air source enters through this flow cross section in the intake tube at a pressure such that at the narrowest point or throat area of the nozzle the air attains sonic speed. A fuel delivery line also discharges at the narrowest point or throat area of the nozzle, and fuel metered in accordance with engine operating characteristics is carried via this fuel delivery line downstream of a fuel metering valve. The quantity of air flowing through the nozzle should be a partial flow of the aspirated air quantity; for instance, it should not be greater than the idling air quantity of the engine, so that at little expense, a continuous flow of air through the nozzle can be effected at sonic speed.Type: GrantFiled: June 5, 1984Date of Patent: December 25, 1984Assignee: Robert Bosch GmbHInventor: Nikolaus Simon
