| titleOfInvention | METHOD FOR UREA INJECTION MANAGEMENT IN A SELECTIVE CATALYTIC REDUCTION SYSTEM |
| abstract | The invention relates to a method for the management of urea injection in a selective catalytic reduction nitrogen oxidation treatment system, called SCR, intended to be installed in the exhaust line (6) of the invention. an engine (2) of a motor vehicle (1), the treatment consisting in chemically reducing, in a catalyst (3), said SCR catalyst, the nitrogen oxides by adding ammonia contained in the urea, the process comprising the following steps: - the temperature of the gases in the exhaust line (6) of the engine (2), upstream of the SCR catalyst (3), is measured, - if the measured temperature is greater than a predetermined minimum value, called minimum injection temperature, a urea injection (5) is ordered, - if the measured temperature is lower than the minimum injection temperature, the following sub-steps are used: ○ a mass of ammonia is determined stored in the catalyst SCR (3), the qua the amount of ammonia necessary to obtain a conversion of the nitrogen oxides greater than a predetermined value, if the mass of ammonia stored in the catalyst is less than this necessary quantity, the activation of a heating mode of the gases is controlled exhaust. and urea injection into the system. |
