Nitrogen oxides selective catalytic reduction system for use with exhaust gases line of diesel engine, in car, has identification unit interdependent of tank and comprising unique code allocated to tank and readable by control unit

摘要

The system (1) has a storage tank (3) for a reducing agent or a precursor of reducing agent of nitrogen oxides. The tank includes an identification unit (14) interdependent of the tank, and comprises a unique code allocated to the tank and readable by a control unit (12), where the unique code is a measurable characteristic of an electrical circuit. The tank includes a heating unit and a solid substrate (10) adapted to store the reducing agent or the precursor of reducing agent of nitrogen oxides, and to slacken it in gas form by the effect of heating by the heating unit.
