ENGINE SYSTEM, AND SHIP

摘要

An engine system (100), wherein: when the amount of the exhaust gas discharged from the engine body (10) has reduced, the ratio of the amount of an exhaust gas supplied to a supercharger (20) relative to the amount of the exhaust gas discharged from an engine body (10) is increased by decreasing the area of an opening in a variable nozzle (32); and when the amount of the exhaust gas discharged from the engine body (10) has become greater, the ratio of the amount of the exhaust gas supplied to the supercharger (20) relative to the amount of the exhaust gas discharged from the engine body (10) is decreased by increasing the area of the opening in the variable nozzle (32).
