CATALYST CONVERTER DEVICE |
摘要 |
<p>To obtain a catalytic converter device that can suppress a drop in the effect of heating a catalyst carrier caused by water droplets produced in an exhaust pipe. A holding mat (26) that holds a catalyst carrier (14) in a case cylinder (28) is given a three-layer structure comprising an inside fiber layer (30), a solid layer (32), and an outside fiber layer (34). The solid layer (32) projects toward an upstream side from an upstream-side end face (14A) of the catalyst carrier (14), and an interstice portion (40) is configured between the projecting portion (38) and the case cylinder (28). Water droplets adhering to the inner peripheral surface of the case cylinder (28) do not reach the catalyst carrier (14) because the projecting portion (38) serves as a barrier.</p> |
