FIELD: mechanical engineering; spark ignition internal combustion engines; catalytic conversion of exhaust gases. SUBSTANCE: device has at least two cellular structure members placed in one common tube-like housing through which exhaust gas passes. Adjacent cellular structure members are mechanically connected to each other by support members getting inside cellular structure members. First cellular structure member is installed in outer tube-like housing with clearance, and it has at least two envelopes forming surface of housing of first member are connected, respectively, with current leads. Device has electrically insulated connecting members, each being connected by one end with corresponding envelope and by other, with adjacent cellular structure member. Common tube-like housing has at least one encircling corrugation fitting tube-like housing of second cellular structure member. EFFECT: simplified design. 15 cl, 3 dwg
