Abstract
An exhaust purification system is equipped with: a linear exhaust pipe through which exhaust gas emitted from an engine passes; an injection nozzle that injects a reducing agent into the exhaust pipe at an oblique angle with respect to the axial direction of the pipe; a reduction catalyst that is provided in the exhaust system downstream from the injection nozzle, and that purifies the exhaust gas by causing the exhaust gas to react with the reducing agent; and a mixer member that is provided inside the exhaust pipe, downstream from the injection nozzle, and that causes the reducing agent to mix with the exhaust gas and diffuse. The mixer member includes multiple fins protruding downstream, and is arranged inclined inside the exhaust pipe such that the upstream surface thereof faces the injection opening surface of the injection nozzle.
