Abstract
An exhaust gas purifier including a casing, SCR catalysts (comprising a first SCR catalyst and a second SCR catalyst), a first backflow prevention plate, and a second backflow prevention plate. In the casing, at least a part of the catalyst passage and at least a part of the bypass passage are formed. The SCR catalysts are disposed in the catalyst passage and selectively reduce NOx included in an exhaust gas flowing in the catalyst passage. The first backflow prevention plate prevents or reduces a backflow of an exhaust gas from a second exhaust passage to the catalyst passage.
