EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an exhaust emission control device preventing accumulation of deposit in an injection space and preventing poor supply of an additive into an exhaust gas passage due to the deposit.

SOLUTION: This device includes an exhaust path 34 connected to an exhaust port of an engine, an exhaust emission control catalyst disposed in the exhaust path, an additive injection path 36 providing communicating to the exhaust path at an upstream side of the exhaust emission control catalyst, and an injector 35 injecting additive to the additive injection path and supplying the additive to the exhaust emission control catalyst. A guide part guiding part of exhaust gas to flow into the additive injection path is disposed at a downstream side of the additive injection path in the exhaust path.
