FIELD: removal of soot particles from exhaust gases during operation of internal combustion engines.
SUBSTANCE: proposed method consists in passing the exhaust gas flow through flow-type trap. Some particles are entrapped in trap in swirled state during such period of time when probability of their interaction with nitrogen dioxide contained in exhaust gases exists till complete elimination of entrapped particles. Trap has flow passages for free flow of exhaust gases for forming swirling or dampening zones.
EFFECT: avoidance of choking of trap by solid particles, thus ensuring continuous regeneration; reduced losses of pressure in trap.
