  • Arrangement for supplying a rail vehicle with electrical energy
    Patent number: 9604654
    Abstract: The invention relates to an arrangement for supplying a rail vehicle with electrical energy. One electrical machine is allocated to each of at least two internal combustion engines for generating electrical energy. A common controller is designed to start the internal combustion engines individually as required. At least one pre-heating device is designed to pre-heat the internal combustion engines before a start. A temperature detection device is thermally coupled to the internal combustion engines. The controller is designed, during an operation of one of the internal combustion engines, to start another of the internal combustion engines if, due to cooling of the other internal combustion engine, a temperature of the other internal combustion engine detected by a temperature identifying device reaches or exceeds a temperature threshold.

  • Operation of an internal combustion engine
    Patent number: 9091203
    Abstract: An apparatus to use waste heat from an internal combustion engine in a vehicle, wherein the apparatus has an exhaust gas line to remove exhaust gases from the internal combustion engine, the exhaust gas line is thermally connected to a high-temperature side of a thermoelectric generator, and a latent heat accumulator is thermally connected to the high-temperature side of the thermoelectric generator.
