Patent number: 6886399Abstract: A method detects mass flows to the intake manifold of an internal combustion engine having a device for controlling the air supply to the intake manifold and having a sensor for detecting the intake manifold pressure and having a control apparatus for evaluating a trace of the intake manifold pressure. In the context of the method, when the internal combustion engine is switched off, the supply of air to the intake manifold is reduced in a predetermined manner and the trace of the intake manifold pressure, which adjusts thereupon, is evaluated for detecting the mass flows.Type: GrantFiled: December 22, 2001Date of Patent: May 3, 2005Assignee: Robert Bosch GmbHInventors: Eberhard Schnaibel, Wilfried Tuleweit, Manfred Pfitz, Roland Herynek, Holger Bellmann, Gholamabas Esteghlal, Detlef Heinrich, Lutz Reuschenbach, Georg Mallebrein

Patent number: 6851399Abstract: This invention is based on a method for monitoring a cooling fluid circuit (16) of an internal combustion engine (10), with at least one heat exchanger (18, 22), a regulating valve (26), a cooling fluid pump (32), and an electronic control unit (76). The invention proposes that the control unit (76) predetermine a permissible upper and lower deviation of a reference parameter from a desired value, based on operating parameters of the internal combustion engine (10) and with the aid of deviation characteristic fields (56, 58), and that it compare these permissible upper and lower deviations to a difference between a desired value and an actual value of the reference parameter, wherein the actual value is determined based on parameters of the volumetric flow of the cooling fluid, possibly with the aid of characteristic fields (42, 46, 74).Type: GrantFiled: April 17, 2002Date of Patent: February 8, 2005Assignee: Robert Bosch GmbHInventors: Roland Herynek, Martin Vollmer

Patent number: 6722350Abstract: An internal combustion engine (1), especially of a motor vehicle, is described. The engine (1) is provided with a combustion chamber (4) into which fuel can be injected in a first operating mode during a compression phase and in a second operating mode during an induction phase. The engine (1) is provided with a control apparatus (18) for switching over between the operating modes.

Patent number: 6625974Abstract: An internal combustion engine (1), especially of a motor vehicle, is described which is provided with a combustion chamber (4) into which fuel can be injected in a first operating mode during a compression phase and in a second operating mode during an induction phase. An exhaust-gas pipe (8) is provided in which a catalytic converter (12) is mounted. The engine (1) is provided with an exhaust-gas recirculation from the exhaust-gas pipe (8) to an intake manifold (7). A control apparatus (18) is provided for controlling (open loop and/or closed loop) operating variables of the engine (1). The exhaust-gas recirculation rate of the exhaust-gas recirculation is controllable (open loop and/or closed loop) by the control apparatus (18), inter alia, in dependence upon the temperature of the catalytic converter (12).Type: GrantFiled: June 29, 2001Date of Patent: September 30, 2003Assignee: Robert Bosch GmbHInventor: Roland Herynek

Publication number: 20030177844Abstract: A method for determining mass flows into the inlet manifold (3) of an internal combustion engine, with means (5, 6, 9), for controlling the air intake into the inlet manifold (5, 6, 9), means (4), for determining the inlet manifold pressure and means (11) for evaluating the inlet manifold pressure curve, is disclosed. Within the disclosed method, the air intake into the inlet manifold, on switching off the internal combustion engine, is reduced by a set amount and the curve for the inlet manifold pressure thus produced is evaluated for the estimation of the mass flows and a leak in the inlet manifold proven by an increased rate of pressure change.Type: ApplicationFiled: September 16, 2002Publication date: September 25, 2003Inventors: Eberhard Schnaibel, Wilfried Tuleweit, Manfred Pfitz, Roland Herynek, Holger Bellmann, Gholamabas Esteghlal, Detlef Heinrich, Lutz Reuschenbach, Georg Mallebrein

Publication number: 20030075158Abstract: A valve flow characteristic line is adapted by weighting the valve position as an input variable using a variable offset value. To calculate a robust model of the intake manifold pressure, a modeled partial pressure of the recirculated exhaust gas is determined so that it differs as little as possible from the actual partial pressure of the recirculated exhaust gas. To do so, a modeled partial pressure of the recirculated exhaust gas is derived from a flow characteristic of a valve in an exhaust gas recirculating line as a function of the valve position. The modeled partial pressure of the recirculated exhaust gas derived from the flow characteristic is corrected adaptively as a function of the difference between the modeled intake manifold pressure and a measured intake manifold pressure.Type: ApplicationFiled: October 11, 2002Publication date: April 24, 2003Inventors: Leonhard Milos, Ernst Wild, Jochen Gross, Oliver Schlesiger, Kristina Eberle, Roland Herynek, Patrick Janin, Manfred Pfitz

The control apparatus (11) or its software has a plurality of functions (12) and a scheduler (13) for activating the functions (12). Operating modes are assigned to the functions (12) and the functions (12) are activated by the scheduler (13) in dependence upon the assigned modes of operation.Type: GrantFiled: December 7, 2000Date of Patent: April 1, 2003Assignee: Robert Bosch GmbHInventors: Ernst Wild, Roland Herynek, Miriam Steger, Gudrun Menrad, Lutz Reuschenbach, Michael Oder, Werner Hess, Hans Hillner, Georg Mallebrein, Christian Koehler
