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 3):
The exhaust purification system according to  claim 1 ,\n wherein the linear piping is formed in a cylindrical shape, and wherein the mixer member comprises:\n a ring member having an elliptic annular shape, an outer periphery of the ring member being fixed to an inner periphery of the linear piping; \n a plurality of plate members arranged inside the ring member in a grid shape; and \n the plurality of the fins that is integrally formed with the plurality of plate members and is bent at a predetermined angle.
