  • Patent number: 8281684
    Abstract: A steering column arrangement includes a steering spindle, which rotates about its longitudinal axis and serves to transfer a torque, generated by a steering wheel, to a steering gear, and a blocking device, which prevents the rotational motion of the steering spindle, especially in the event of a collision. The blocking device includes a stator, which is stationary in relation to the rotational motion of the steering spindle, and against which a blocking element is mounted in a relatively moveable manner. To prevent, in a reliable manner, an undesired twisting of the steering wheel, especially in the event of a collision, the blocking element is moveable into a locked position in a radial direction toward the steering spindle.

  • Patent number: 8281761
    Abstract: An internal combustion engine has a plurality of cylinders and an air intake system. The air intake system is formed from at least one distributor pipe, a plurality of intake pipes, and at least one plenum. The plenum is located between the distributor pipe and the intake pipes. Here, the combustion air is fed to the air intake system via an air guiding duct which opens out into the distributor pipe. The charge pressure of the combustion air is reduced between the outlet out of the compressor and the inlet into the combustion chamber of the internal combustion engine. A distributor pipe length is dimensioned as a function of an equivalent distributor pipe diameter such that it is possible for a reduction in the charge pressure to be obtained within the air intake system by way of an expansion, with the expansion taking place partially in the plenum in the respective intake pipe and/or within the distributor pipe.
