Summary:

The electrostatic soot filter consists of an electrostatic fieldand a downstream cyclone. The usually very small soot particles areseparated in the field and converted into considerably largerparticles. In the cyclone, the soot is separated and the exhauststream is divided into two streams, whereby the first, as a cleangas stream, should contain no soot particles and the other streamshould contain all the soot particles. Whereas the clean gas streamcan leave the vehicle by way of the exhaust pipe, the exhaust gasstream containing soot is recirculated into the intake manifold ofthe engine. The engine burns the soot with high conversion rates,so that particle emission improvements of 80% can be achieved insteady-state operation. In the CVS test the emission of particlesis reduced by 50% with a first test sample.Due to the continuous operation of the filter and the burning ofthe soot in the engine, the particularly critical problem ofregeneration does not apply in this case. The danger of cloggingcan virtually be ruled out even if the filter is fitted at aconsiderable distance from the engine. This loss in pressurecorresponds to that of a silencer. A drawback is the stillcomparatively large size (approximately 1 1/2 times the volume of arear silencer)
