Abstract: A device for the post-treatment of the exhaust gas of an internal combustion engine comprises a conduit defining a passage for the flow of the exhaust gas and, from upstream to downstream of the conduit, an injector arranged to inject a reducing agent into the flow passage, and a purifying member. The injector is heated to heat the reducing agent prior to injection. The device further comprises a heating element arranged between the injector and the purifying member.
