DEVICE FOR AND METHOD OF CLEANING EXHAUST GASES OF INTERNAL COMBUSTION ENGINE Russian patent published in 2004 - IPC

FIELD: transport engineering; cleaning of exhaust gases. SUBSTANCE: proposed method is implemented by device including pipeline delivering exhaust gases from exhaust manifold of engine into said device, first and second filters, muffler and exhaust pipe. It contains also damping chamber in which gases expand, buffer plate, diffuser, centrator in which gas flow comes in contact with two external cold air streams, swirl chamber into which part of contaminating gases is directed and from which they are delivered into engine as intake gases, pipeline into which remaining gas flow is directed which is then delivered into muffler and then into exhaust pipe. Swirl chamber includes engine channel through which gases are delivered to fixed vanes, where they expand and pass to nozzle provided with outlet through which gases return to engine inlet. EFFECT: luminary cleaning of gases without delay in coming out. 11 cl, 8 dwg
