SYSTEM FOR PREVENTING THE UREA CRYSTAL FORMATION WITHIN AN EXHAUST GAS AFTER TREATMENT SYSTEM

摘要

System for preventing the urea crystal formation within the ATS, the exhaust ATS comprising a dosing module (DM) having dosage means (J) for producing a spray of urea-based reducing agent defining a spray cone (C) downstream of the dosage means (J), the device comprising an electric heating element (H), suitable to be connected to an electrical energy source, arranged in order to operatively fall within the spray cone (C).
