Abstract
An engine system for a working machine includes an engine disposed in a main body of the working machine, an exhaust manifold coupled to the engine, a tail pipe, an exhaust-gas purification device disposed in the main body and including an exhaust-gas inlet-side housing. The exhaust-gas inlet-side housing includes an exhaust-gas inlet coupled to the exhaust manifold, and an exhaust-gas outlet-side housing including an exhaust-gas outlet coupled to the tail pipe. The exhaust-gas purification device is configured to purify exhaust gas discharged from the engine and to cause the purified exhaust gas to be discharged from the tail pipe to an outside of the engine system. The engine system is configured such that a silencer housing is disposable in the exhaust-gas inlet-side housing, the exhaust-gas outlet-side housing, or both, to attenuate exhaust sound of the engine.
