ABSTRACT:
A device for exhaust gas recirculation in diesel engines is described, in which an exhaust filter for the recirculated exhaust gas is arranged in an exhaust gas recirculation pipe branching off from the exhaust pipe. This exhaust filter insert is arranged in the branch of the exhaust gas recirculation pipe in such a way that its surface on the contamination side lies approximately parallel to the direction of flow of the main exhaust gas stream, to be precise in the region and course of a normal flow line close to the wall. In a preferred embodiment, the filter insert consists of a dimensionally stable porous pipe of sintered ceramic or sintered metal.
