Motor vehicle exhaust gas purifying device, has purification module arranged within housing in such a manner that discharged streams flows through purification module to outlet, and gas porous metal foam body connected upstream of module

摘要

The device has a metallic housing (2) with inlets for a delayed discharge of individual exhaust gas streams (Z1- Z4). The housing has an outlet (4) for dissipation of exhaust gas. A purification module (51 - 54) has a filter unit (6) and catalyst units, and is arranged within the housing in such a manner that discharged streams flows through the module to the outlet. A gas porous metal foam body (8) is connected upstream of the module.
