Patent number: 8079349Abstract: A motor vehicle has an internal combustion engine (1) and a drive train (2) with an electric machine that can be operated as a generator. A supercharger (5) supplies air through a mass flow line (6) to an inlet side of the internal combustion engine (1). The air mass flow line (6) has no throttle valve. The supercharger (5) also selectively can function as a secondary air pump to blow secondary air through a branch (7) of the mass flow line (6) and to an outlet side (21a, 21b) of the internal combustion engine (1) upstream of a catalytic converter. A control unit causes the electric machine to operate as a generator when the supercharger (5) is functioning as a secondary air pump to compensate for excess torque caused by a charge pressure generated by the secondary air.Type: GrantFiled: June 2, 2009Date of Patent: December 20, 2011Assignee: Dr. Ing. h.c.F.

Patent number: 7162865Abstract: The invention relates to a method and an arrangement for controlling a drive unit (1), especially of a vehicle, having a combustion engine (5). The method and arrangement make possible a correct charge control when utilizing a secondary air charger (10) as well as make possible a diagnosis of the secondary air charger (10). Secondary air is blown into an exhaust-gas system (15) of the combustion engine (5) via the secondary air charger (10). The secondary air charger (10) is driven by a pressure drop across an actuating element (20) for adjusting an air supply to the engine (5). The actuating element (20) is driven for adjusting an air supply to the engine (5) corrected in dependence upon an air mass flow driving a turbine (25) of the secondary air charger (10).Type: GrantFiled: November 5, 2003Date of Patent: January 16, 2007Assignee: Robert Bosch GmbHInventors: Rainer Weigand, Karl Dums

Patent number: 5440933Abstract: In a pressure sleeve in particular a vibration pickup, an abutment surface is formed as a circumferential ring at a location radially spaced from a central point. Therefore, the pressure sleeve can be fully pressed against the structure to be monitored by a mounting screw. Therefore a sensor provided with the pressure sleeve can approximately linearily extending and disturbance measuring signals.Type: GrantFiled: March 30, 1994Date of Patent: August 15, 1995Assignee: Robert Bosch GmbHInventors: Hartmut Brammer, Romuald Fries, Karl Dums, Holger Krebs

Patent number: 5398540Abstract: A knock sensor for indirect or direct fixing to an internal combustion engine has a housing (10) with a pressure sleeve (11) on the outer side of which a piezoceramic disk, a seismic mass (16), the contact disks (14), and the insulating disks (13) are arranged. The insulating disks (13) or the piezoelectrical disk (15) are or is made slightly electrically conductive so that the voltage spikes which occur due to the pyroelectrical effect can be easily eliminated. In this way, faulty measuring and interference can be avoided in the electrical circuit connected to the knock sensor.Type: GrantFiled: June 11, 1993Date of Patent: March 21, 1995Assignee: Robert Bosch GmbHInventors: Robert Entenmann, Joerg Bonitz, Stefan Unland, Romuald Fries, Robert Sloboda, Klaus Schenk, Karl Dums
