摘要： This invention relates to an intake system for a multi-cylinder internal-combustion engine operating with exhaust gas recirculation and fuel injection, having an air-guiding casing that is developed in the shape of a box and has a partition that, on the one side, is the wall part for a clean-air side and, on the other side, is a wall part for a mixing duct and a distributor volume that has connecting points for suction pipes of the internal-combustion engine. In the partition, an air-throttle valve is disposed centrally that controls the air inlet into the mixing duct, and downstream of the valve and concentrically to it, the inlet for recirculated exhaust gas is arranged. Passages that extend in an arched course and are located symmetrically with respect to the position of the air-throttle valve connect the mixing duct with the distributor volume.

摘要： An arrangement of a soot filter in the exhaust gas system of an internal combustion engine equipped with an exhaust gas turbocharger whose turbine housing is arranged downstream of the exhaust gas manifold. For purposes of achieving a fastening of the soot filter at the internal combustion engine which is favorable from an assembly point of view, space-saving and compensating changes in length, the soot filter and the exhaust gas turbocharger form a unit which is retained, on the one hand, angularly movably at the exhaust gas manifold by means of a pipe connection of the soot filter and, on the other, at the crankcase by way of supports arranged at the exhaust gas turbocharger on the housing side.
