FIELD: machine building.
SUBSTANCE: invention relates to machine building, to means of reducing toxicity of exhaust gases of internal combustion engines. Catalytic converter consists of housing with catalytic elements, inlet and outlet branch pipes. Vortex tube with outlet of hot gases into catalyst is installed on inlet channel of catalyst, it includes shutoff valve installed in diffuser of cold flow and connected by means of rod with swirler, made with possibility of forced axial movement.
EFFECT: proposed invention makes it possible to reduce duration of heating of catalytic neutraliser of exhaust gases without considerable change of design of serial catalyst.
