Patent number: 11267328Abstract: A drive train (10) for driving a motor vehicle has a combustion engine (12) for providing purely mechanical drive for the motor vehicle. A transmission (16) can be coupled to the combustion engine (12) via a shaft unit (14) for transmitting torque between the motor vehicle transmission (16) and the combustion engine (12). A reserve volume (18) is between the combustion engine (12) and the motor vehicle transmission (16) and is penetrated by the shaft unit (14). The reserve volume (18) can accommodate a high-voltage electric machine for purely electric drive of the motor vehicle or a low-voltage electric machine (32) for applying an electrically generated assistance torque to the motor vehicle transmission (16). As a result, a hybrid functionality can be made available to an at least limited degree, with the result that a cost-effective drive train (10) configured for a hybrid motor vehicle is made possible.Type: GrantFiled: April 18, 2019Date of Patent: March 8, 2022Assignee: Dr. Ing. h. c. F. Porsche AGInventors: Immo Stache, Leo Spiegel, Henrik Schrage

Patent number: 8479509Abstract: A method for operating an internal combustion engine with compression ignition or with spark ignition as a function of an operating point. A specific residual exhaust-gas quantity in the combustion space is set for compression ignition. The internal combustion engine is operated as a function of the operating point by an outlet cam, by which a first outlet opening phase and a second outlet opening phase take place. The second outlet opening phase commences during an inlet opening phase. At a first operating point in a compression-ignition mode, a residual exhaust-gas quantity in a combustion space is dimensioned as a function of a valve interference set between the inlet and the outlet valve during a charge exchange. At a second operating point in the compression-ignition mode the residual exhaust-gas quantity in the combustion space is dimensioned as a function of a duration of the second outlet opening phase.Type: GrantFiled: February 17, 2010Date of Patent: July 9, 2013Assignee: Dr. Ing. h.c.
