EXHAUST MIXER

摘要

An exhaust gas stirring device is to be mounted in a tubular body that forms a flow path for exhaust gas. The exhaust gas stirring device comprises a main body that comprises a plurality of base plates facing one another at specified distances and a plurality of blade portions that are provided on a downstream side of a flow direction of the exhaust gas and are inclined with respect to the flow direction of the exhaust gas. The plurality of blade portions are formed so that there is a route in which vectors X of the individual blade portions, each vector X being defined below, go around in a given direction when viewed from a downstream side of a flow direction D of the exhaust gas. Vector X: a component of a vector in a direction of the blade portion guiding the exhaust gas, in a plane perpendicular to the flow direction of the exhaust gas.
