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

摘要

A device for purifying (1) exhaust gases of a vehicle by selective catalytic reduction including a heated piping (9). The heated piping comprises a fluid conveying pipe (22) including a thermoplastic elastomer, a heating element (21) arranged inside the conveying pipe, and an anti-abrasive layer (23). Preferably, the conveying pipe (22) is made of a polyolefinic matrix based thermoplastic elastomer in which it is intimately dispersed a dynamically vulcanised and EPDM based elastomeric phase.
