Abstract
A multi cylinder internal combustion engine is disclosed having the cylinders arranged in A and B groups. The A cylinders are supplied with an enriched air-fuel mixture, and the B cylinders are supplied with a lean air-fuel mixture. An apparatus for purifying the exhaust gas gathers exhaust gas from the cylinders A and cylinders B and subjects the same to oxidation reaction. Also, the exhaust gas is recycled into the intake system for the cylinders A.
