Abstract: PROBLEM TO BE SOLVED: To enable both improvement of energy recovery efficiency and reduction of emission. SOLUTION: An air-fuel ratio of a primary engine 1 is controlled to become lean. The efficiency is therefore improved, though NOx is contained in exhaust gas. On the other hand, in a secondary engine 2, combustion therein is controlled so that an air-fuel ratio of an entire engine system agrees to a theoretical air-fuel ratio. Exhaust gas of the secondary engine thus has the theoretical air-fuel ratio. Since a three-way catalyst 7 purifies NOx, HC and CO, etc. in the vicinity of the theoretical air-fuel ratio, according to this engine system, both the improvement of energy recovery efficiency and the reduction of emission can be realized at the same time.
