DEVICE FOR DECREASING AMOUNT OF SOOT PARTICLES EXHAUSTED BY HEAT ENGINES Russian patent published in 2000 - IPC

FIELD: mechanical engineering; heat engine exhaust system. SUBSTANCE: owing to addition of catalytic additive into fuel, point of ignition of soot particles at afterburning is reduced to 300-350 C and process of regeneration of filter in reservoir starts comparatively early. According to invention, filtering material consists of large number of hoses woven thinnest ceramic threads and coiled into ring along which heat resistant wire is passed. Wire passes through each separate loop of woven structure in parallel with ceramic thread. EFFECT: provision of required service life of filter capable of withstanding vibration and mechanical loads. 16 cl, 7 dwg
