Zusammenfassung:A muffling apparatus of the present invention having an exhaust emission purifying function, including a turning portion in an inside of an exhaust gas flow passage, and having an injection nozzle disposed in an upstream side exhaust gas flow passage of the turning portion , for injection-supplying a liquid reducing agent; and a reduction catalytic converter disposed in a downstream side exhaust gas flow passage of the turning portion , for reductively purifying nitrogen oxides with the liquid reducing agent. The apparatus further includes a diffusing member , which generates a vortex flow of a gas traveling in a vertical plane of the turning portion to diffuse the liquid reducing agent.
