摘要： An internal combustion engine exhaust gas system includes an EGR arrangement adapted to lead a first flow of exhaust gas, the EGR flow, from an outlet side of the engine to an inlet side of the engine, an exhaust gas conduit adapted to lead away a second flow of exhaust gas, the exhaust flow, from the outlet side of the engine, and an energy recovering unit, such as a turbo, associated with the exhaust gas conduit. The unit is adapted to recover exhaust gas energy from the exhaust flow. The system includes a heat exchanger adapted to allow heat exchange between at least a part of the EGR flow and at least a part of the exhaust flow, the heat exchanger being associated with the exhaust gas conduit at a position downstream the energy recovering unit.

摘要： Method and device for reduction of a gas component in an exhaust gas flow of a combustion engine (1) that is adapted for operation by a lean air/fuel mixture. An exhaust pipe (21) is included for transport of the exhaust gas flow from the engine (1). A separation unit (22) is also included that is arranged along the exhaust pipe (21), which separation unit (22) has a wall structure (32) of a material which provides separation of the gas component from the exhaust gas flow by means of a selective passage of the gas component before other gas components in the exhaust gas flow. The method provides for a reduction and a separation unit that is intended to be utilized during such a reduction. An improved reduction of in particular NOx compounds from a so-called “lean-burn” engine is also provided.
