A crash-tolerant system arrangement in an engine compartment situated in the front end region of a motor vehicle includes an exhaust emission control system having an essentially cylindrical first catalytic converter housing situated in front of the exhaust gas turbocharger in the travel direction. The exhaust gas turbocharger is mechanically connected to an exhaust gas manifold via a first fastening device, and to an engine block via a second fastening device, the first and the second fastening devices being designed in such a way that a detachment of the connection of the exhaust gas turbocharger to the exhaust gas manifold and/or a detachment of the connection of the exhaust gas turbocharger to the engine block take(s) place within a predefined upper value range for the pressure force.

A combination of an adsorbent with a catalyst for internal combustion engines. The adsorbent-catalyst combination is built up in two or more alternating layers of zones, which are coated to be adsorbing, and zones, which are coated to have catalytic activity, and are connected in series in relation to the flow of exhaust gas. The zones having adsorbing activity are to be designed thermodynamically so that they have a lesser heat transfer than the zones having catalytic activity, so that the zones having catalytic activity have a higher support temperature than the upstream zones having adsorbing activity.

The exhaust gas equipment for an internal combustion engine contains an exhaust pipe, an exhaust gas cleaner and an adsorption filter, to whose filter body exhaust gas is admitted by a controlled exhaust gas butterfly. In order to prevent damage to the filter due to overheating, in an arrangement of the exhaust gas equipment which is economical in installation space where the adsorption filter is located along the course of the exhaust pipe and a filter body surrounds the latter coaxially, a thermal insulation element is provided between the filter body and exhaust gas flow. The thermal insulation element has transfer openings at least partially outside the exhaust pipe section surrounded by the filter body for guiding the exhaust gas flow through the filter body.

The invention relates to bearing support of a throttle valve shaft in the housing of an exhaust gas line in which the shaft is rotatably supported on both sides in a bearing sleeve element constructed cup-shaped. The cups themselves are retained by spring force against the housing extending correspondingly conically within these areas. In order to keep small the actuating forces necessary for the rotation of the throttle valve shaft, each bearing sleeve element is retained by itself against the housing by means of a spring supported at the housing and the securing of the shaft against any axial displacement takes place by a separate axial bearing.
