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  13,  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.

Claim (Index 1):
An exhaust purification system comprising:\n an exhaust pipe, which has a straight line shape, and through which exhaust gas discharged from an engine flows; an injection nozzle configured to inject a reducing agent into the exhaust pipe in a direction obliquely with respect to a pipe axial direction; a reduction catalyst provided in an exhaust system that is on a downstream side of the injection nozzle and configured to purify the exhaust gas by reacting the exhaust gas with the reducing agent; and a mixer member provided inside the exhaust pipe on the downstream side of the injection nozzle and on an upstream side of the reduction catalyst and configured to mix and diffuse the reducing agent with the exhaust gas, wherein the mixer member comprises a plurality of fins protruding to the downstream side, and wherein the mixer member is arranged inside the exhaust pipe in an inclined manner such that an upstream side surface of the mixer member, which is on an opposite side of the fins, faces an injection port surface of the injection nozzle.
