  • Patent number: 10427528
    Abstract: A vehicle may include an internal combustion engine configured to drive a plurality of wheels of the vehicle via a drive train. A waste heat utilization device may drive an electric generator by converting the waste heat generated by the internal combustion engine. The generator may be electrically connected to an on-board electrical system comprising an electric energy store and at least one electric consumer. An electric motor may be coupled to the drive train to provide an additional drive. The generator may convert kinetic energy generated by the waste heat utilization device into electrical energy and to provide the electrical energy to the on-board electrical system and/or to the electric motor. The electric motor may convert electrical energy provided by the electric energy store of the on-board electrical system and/or by the generator into kinetic energy and may couple the same into the drive train.

  • Patent number: 8844284
    Abstract: The invention relates to an internal combustion engine system (1), particularly in a motor vehicle, comprising an internal combustion engine (2), a fresh gas system (3) for supplying fresh gas to the internal combustion engine (2), an exhaust gas system (4) for discharging exhaust gas from the internal combustion engine (2), and an exhaust gas recirculation system (5) for removing exhaust gas from the exhaust gas system (4) at a removal point (11) and introducing the removed exhaust gas into the fresh gas system (3) at an introduction point (12). In order to improve exhaust gas recirculation, the exhaust gas system (4) is equipped with an exhaust gas valve (14) downstream of the removal point (11) in order to control the penetrable cross-section of the exhaust gas system (4).

  • Patent number: 8176902
    Abstract: The invention relates to an internal combustion engine system, especially in a motor vehicle, comprising an internal combustion engine, a make-up gas installation for supplying make-up gas to the internal combustion engine, an exhaust gas installation for evacuating the exhaust gas from the internal combustion engine, and an exhaust gas recirculation installation for extracting exhaust gas from the exhaust gas installation and introducing the extracted exhaust gas into the make-up gas installation. In order to improve the exhaust gas recirculation, two make-up gas paths through which make-up gas can flow in parallel are formed in a control section of the make-up gas installation, a make-up gas valve being arranged in each make-up gas path, for controlling the cross-section of the respective path through which gas can flow.
