エンジンの排気浄化装置。[Scope of Claim for Utility Model Registration] A passage regulating plate comprising a catalyst unit for exhaust purification and a catalyst case housing the unit, and defining a passage area for exhaust gas facing the outlet end of the catalyst unit in the case. The passage restriction plate has a gas vent that allows exhaust gas to pass only near the center of the plate surface, and the passage restriction plate is close to the outlet end of the catalyst unit and extends to the peripheral area of the unit. between the operating position in which exhaust gas is prevented from passing through the catalyst unit and the standby position in which the passage restriction plate is located sufficiently far from the outlet end of the catalyst unit.
An engine exhaust purification device in which the posture of a passage regulating plate can be changed using an operating means.
