Abstract

[Problem] To provide an exhaust gas recirculation system in which engine deposits are less likely to be generated, an engine system, a control method of an exhaust gas recirculation system, and a control program.[Solution] An exhaust gas recirculation system 4 recirculates, as EGR gas, at least part of exhaust gas discharged from an engine main body 2 from an exhaust port 202 to an intake port 201 of the engine main body 2. The exhaust gas recirculation system 4 includes an EGR path 41, a cooling unit 43, a bypass path 44, and a control unit. The EGR path 41 connects the exhaust port 202 and the intake port 201 and allows the EGR gas to pass through the EGR path 41. The cooling unit 43 includes a cooling path 431 included in the EGR path 41 and cools the EGR gas passing through the cooling path 431. The bypass path 44 connects an inlet and an outlet of the cooling path 431. The control unit recirculates the EGR gas in a bypass mode in which the EGR gas is caused to flow through the bypass path 44 to bypass the cooling path 431 when a determination condition is satisfied.
