FIELD: mechanical engineering; diesel and forced ignition engines; cleaning of exhaust gases. SUBSTANCE: housing of catalytic converter has separating partition with ribs and through ports. Hollow soot ceramet porous unit and ceramet porous reduction catalytic unit are coaxially fitted on mounting ribs and mounting clamps. External surfaces of units are formed by longitudinal solid or hollow ribs. Ceramet porous reduction catalytic unit is installed coaxially relative to metal porous oxidation catalytic units. Housing is provided with supply branch pipe divided by partition into oxidizer supply channel and auxiliary gas supply channel. EFFECT: increased strength of exhaust gas catalytic converter, reduced noise and improved quality of exhaust gas cleaning from nitrogen oxides. 3 dwg
