The engine (2) includes a compressor (22), a three way catalyst (36), a canister (46), an evaporated fuel passage (54), an ejector (56), and a purge control valve (58). The controller includes an ECU (100). The ECU (100) is configured to decrease an opening degree of the purge control valve (58) in response to an increase in pressure on the downstream side of the compressor (22) in a lean supercharging range. The is a range in which an operation air-fuel ratio of the internal combustion engine (2) is leaner than a theoretical air-fuel ratio of the internal combustion engine (2), and in which the pressure on the downstream side of the compressor (22) is higher than pressure on the upstream side of the compressor (22).",
