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.
