Summary:

This publication represents tests on a new particulate trapping system based on metal fleece as the trapping medium. The tested trap system uses several traps of pleated, highly temperature-resistant metal fleece with parallel paths directly in the exhaust stream of the diesel engine. For the regeneration of the traps respectively one of the traps is separated from the exhaust stream by a rotary slide valve and brought up to the regeneration temperature through direct electrical heating of the metal fleece, so that the soot of the trap surface burns as a result of regeneration air being supplied.Based on the description of the trapping system, the tests on the test bench for determining the particulate separation rates are illustrated. In another test the regeneration of the traps, loaded before on the engine, was studied in a lab test. Here the optimal regeneration parameters and the degree of the secundary emissions of gaseous exhaust components was determined. The continuous regeneration of the traps, as conducted on a running engine, shows a good function of the tested trapping system in principle and makes further development works and tests appear promising
