An engine unit includes: an engine that is able to independently inject fuel into cylinders; an exhaust gas recirculation device that recirculates exhaust gas of the engine to intake air; a cleaning device that cleans exhaust gas from the engine; and a control device that controls the engine and the exhaust gas recirculation device. The control device performs control such that an amount of exhaust gas recirculated to intake air is less when fuel cutoff is performed for some cylinders out of all cylinders of the engine than when fuel is injected into all the cylinders of the engine.
