摘要： [Object] To provide an engine system used for a working machine and configured to facilitate the change of an exhaust-gas discharging structure for an engine 1 for remodeling from a working machine (engine) conforming to an exhaust-gas purification specification into a working machine 211 (engine 1) conforming to a silencer specification. [Means of Realizing the Object] An engine system for a working machine includes an engine 1 disposed in a main body of the working machine, an exhaust manifold 7 disclosed in the main body and coupled to the engine 1, a tail pipe 135 disposed in the main body, an exhaust-gas purification device 2 disposed in the main body and including an exhaust-gas inlet-side housing 44 including an exhaust-gas inlet coupled to the exhaust manifold 7, and an exhaust-gas outlet-side housing 45 including an exhaust-gas outlet coupled to the tail pipe 135, the exhaust-gas purification device 2 being configured to purify exhaust gas discharged from the engine 1 and cause the purified exhaust gas to be discharged from the tail pipe 135 to an outside of the engine system, and a silencer housing 42 disposed as needed in any one or both of the exhaust-gas inlet-side housing 44 and the exhaust-gas outlet-side housing 45 to attenuate exhaust sound of the engine 1.
