An emissions control system for rich-burn internal combustion engines, includes a reaction chamber (7) for thermal oxidation of exhaust gas fuel values. A passive means (5, 4) utilizes exhaust flow energy (2) for induction of air into engine exhaust gas, and a duct (3) transfers the exhaust gas together with the inducted air into the reaction chamber (7) for thermal oxidation. To achieve a high degree of efficiency the thermal oxidation is facilitated by thorough mixing of air and exhaust gas by recirculation means (9) to insure gas phase thermal reaction.
