Abstract
There is provided an engine exhaust treatment device in which stick of a nozzle portion of a urea water injector can be suppressed. The engine exhaust treatment device includes: an SCR catalyst case housing an SCR catalyst; an SCR exhaust inlet pipe; and the urea water injector and the nozzle portion of the urea water injector is directed toward an inside of the SCR exhaust inlet pipe. An exhaust deflector is provided in the SCR exhaust inlet pipe and the exhaust deflector is mounted to an inner peripheral face of the SCR exhaust inlet pipe on an exhaust upstream side of the urea water injector so that exhaust flowing toward the nozzle portion of the urea water injector is deflected by the exhaust deflector and diverted from the nozzle portion.
