1. A selective catalytic reduction (SCR) system comprising:
- an exhaust pipe for receiving an exhaust gas from an engine;
a selective catalytic reduction (SCR) unit provided downstream of the exhaust pipe; and
a first mixing element including a meshed body that defines a first surface, a second surface, and a plurality of openings extending from the first surface to the second surface,wherein the first surface and the second surface are parallel to each other and define an angle relative to a flow direction of the exhaust gas, the angle being less than 90 degrees.

Abstract
A selective catalytic reduction (SCR) system includes an exhaust pipe for receiving an exhaust gas from an engine. A selective catalytic reduction (SCR) unit is provided downstream of the exhaust pipe. A first mixing element including a meshed body defines a first surface, a second surface, and a plurality of openings extending from the first surface to the second surface. The first surface and second surface are parallel to each other and define an angle relative to a flow direction of the exhaust flow. The angle is less than 90 degrees.

16. A mixing device provided in an exhaust pipe upstream of a selective catalyst reduction (SCR) system comprising:
-
a first meshed body defining a first surface, a second surface, and a plurality of openings extending from the first surface to the second surface, wherein the first surface and the second surface are parallel and define an angle relative to a flow direction of an exhaust gas, the angle being less than 90 degrees; and a plurality of tabs extending outwardly from at least one of the first surface and the second surface. - View Dependent Claims (17, 18, 19, 20)
