Abstract: To provide a configuration that can discharge condensed water remaining in an exhaust gas passage in an engine in which a catalyst is placed in the exhaust gas passage. An engine system (100) is an engine system having an engine (10) in which a catalyst (6) is placed in an exhaust gas passage (31). The engine system (100) has a determination device (81a) for determining whether or not the catalyst (6) is immersed in the condensed water condensed from exhaust gas in a cold state and remaining in the exhaust gas passage (31) when the engine (10) is started, and an operation continuing device (81b) that allows operation of the engine (10) to continue when it is determined that the catalyst (6) is immersed in the condensed water so that a discharge operation time Te exceeds a required time.
