  • Patent number: 11448118
    Abstract: A two-stage turbocharged internal combustion engine comprises a low-pressure stage turbocharger mounted at a first end side of an engine block and a high-pressure stage turbocharger mounted at the same first end side of the engine block. The respective turbochargers are mounted via a mounting structure, Which also accommodates the charge air coolers associated with the turbochargers. In order to obtain a compact arrangement and reduce a length of pipe connections between the different components, the different charge air coolers are mounted to mounting structure such that they overlap in a plan view of the internal combustion engine. Further, flow directions of charge air in the different charge air coolers are opposite to each other.

  • Patent number: 10864938
    Abstract: A method for monitoring the condition of an electronic power steering apparatus or of at least one part of the electronic power steering apparatus of a motor vehicle includes continually capturing acceleration measured values in a region of the electronic power steering apparatus during a driving mode of the motor vehicle and continually providing the captured acceleration measured values to a damage computation section in the form of a damage meter that continuously sums the acceleration measured values and continually forms therefrom at least one variable characterizing a degree of damage to the electronic power steering apparatus or to the at least one part of the electronic power steering apparatus. The method further includes continually comparing the variable with at least one prescribed limit value.
