摘要： An exhaust gas system for an internal combustion engine includes an intake system and an exhaust outlet interconnected by an exhaust gas recirculation line having an exhaust treatment unit and a heat exchanger. The heat exchanger has a first back pressure and the exhaust treatment unit has a second back pressure, smaller than the first back pressure. The exhaust treatment unit is disposed at such a first distance from the heat exchanger in flow direction that, during operation, a gas flow entering the exhaust treatment unit is homogenized. The exhaust gas system permits an advantageous configuration of a heat exchanger and an exhaust treatment unit, such as for example a honeycomb body in the exhaust gas recirculation line, in which both the heat exchanger and the exhaust treatment unit can have a smaller structure than in conventional systems. This reduces costs considerably for equipping such a system.

摘要： An exhaust gas system for an internal combustion engine includes a first exhaust treatment unit with a first back pressure and a second exhaust treatment unit with a second back pressure being higher than the first back pressure. The system advantageously enables the configuration of systems having two exhaust treatment units that are disposed one behind the other in flow direction. The first and/or second exhaust treatment unit can have a smaller construction due to the homogenization of flow. This applies, for example, when an oxidation-type catalytic converter is provided as the first exhaust treatment unit and when a particulate filter is provided as the second exhaust treatment unit. The homogenization of flow in the first exhaust treatment unit increases the conversion rate so that the first and/or second exhaust treatment unit can be provided with a smaller construction. This saves considerable costs when configuring such systems.
摘要翻译：用于内燃机的废气系统包括具有第一背压的第一排气处理单元和具有高于第一背压的第二背压的第二排气处理单元。该系统有利地实现具有在流动方向上一个接一个地布置的两个排气处理单元的系统的配置。由于流动的均匀化，第一和/或第二排气处理单元可以具有较小的结构。这适用于例如当提供氧化型催化转化器作为第一排气处理单元时，并且当设置微粒过滤器作为第二排气处理单元时。第一排气处理单元中的流动的均匀化提高了转化率，使得第一和/或第二排气处理单元可以具有较小的结构。这在配置这样的系统时节省了相当大的成本。
