Abstract
An arrangement for removing soot particles from the exhaust stream of a diesel internal combustion engine in such a manner that the soot particles are caught between conductor elements disposed at different potential, produce a short circuit and thereby burn off. In order to be able to realize a purification of the exhaust gas stream without a significant increase of the exhaust gas counterpressure, a centrifugal separator is connected to the exhaust gas line, which passes over into a soot particle collecting chamber constructed axially symmetrical to the longitudinal axis thereof; a predetermined number of electrodes is arranged in turn in the soot particle collecting chamber at a slight distance to the casing interior surface whereby the electrodes among one another or the electrodes and the soot particle collecting chamber itself are at a different potential.
