DEVICE FOR PURIFYING EXHAUST GASES OF A VEHICLE BY SELECTIVE CATALYTIC REDUCTION INCLUDING A HEATED PIPING

摘要

A device for purifying exhaust gases of a vehicle by selective catalytic reduction including a heated piping. The heated piping comprises a fluid conveying pipe including a thermoplastic elastomer, a heating element arranged inside the conveying pipe, and an anti-abrasive layer. Preferably, the conveying pipe is made of a polyolefinic matrix based thermoplastic elastomer in which it is intimately dispersed a dynamically vulcanized and EPDM based elastomeric phase.
