DEVICE FOR PREPARING A REDUCING AGENT PRECURSOR SOLUTION FOR THE SUBSEQUENT TREATMENT OF EXHAUST GAS

摘要

The invention relates to a device (10; 50) for preparing a reducing agent precursor solution for reducing nitrogen oxides in the exhaust gas of a combustion engine (12). The device (10; 50) is characterized in that it has a controllable heating element (32; 64) and a catalytic coating (38) that comes into contact with the reducing agent precursor.
