Abstract: Exhaust gas post treatment system for nitrogen oxide reduction of internal combustion engines operated with excess air. A partial exhaust gas stream is branched off upstream of an SCR catalytic converter for reducing nitrogen oxides. A metering device delivers to the partial exhaust gas stream reduction agent, which is ammonia or a material that releases ammonia downstream of the supply location as a result of the hot exhaust gas. The partial exhaust gas stream is returned to the exhaust gas stream downstream of the supply location and upstream of the SCR catalytic converter, which reduces the 1J nitrogen oxides in the exhaust gas stream with the aid of the ammonia or released ammonia, by selective catalytic reduction, to nitrogen and water vapor.

Abstract: A safety belt retractor, especially in vehicles, is provided that includes a belt shaft as a carrier for a belt that is wound thereon and a vehicle sensitive and/or belt sensitive controllable block device for the belt shaft. The block device includes a force limiting device, effective in the event of a block event, the force limiting device having a viscous medium-filled housing with at least one fixedly positioned contour and a counter-contour that is rotatably displaceable in response to a block event, so that the relative movement between the contour and the counter-contour forces the viscous medium between the surfaces arranged for this purpose. The level of the force limitation applied by the force limitation device is adjustably settable as a function of the parameters associated with the buckled-in passengers via a variation of the inner pressure in the viscous medium-filled housing.
