Abstract: [Problem] In a case where a risk of accumulating deposits on an EGR valve is low, the EGR valve is controlled to be opened as much as possible, and accordingly, emission of NOx contained in exhaust gas to external environment is reduced as much as possible. [Solution] An engine includes a control unit that controls the EGR valve. The control unit selects a predetermined control mode from at least a first mode, a second mode, and a third mode according to at least an engine speed and a fuel injection amount, and controls the EGR valve in the selected control mode. The first mode is a control mode in which the EGR valve is fully closed. The second mode is a control mode in which the opening degree of the EGR valve is adjusted according to the operation state of the engine. The third mode is a control mode in which an ON period in which the opening degree of the EGR valve is adjusted according to the operation state of the engine and an OFF period in which the EGR valve is fully closed are repeated.
