Method and control system for a diesel engine equipped with an SCR system for reducing the nitrogen oxide content in the exhaust gases of said engine, said SCR system comprising a converter containing a catalyst, positioned on the exhaust line of said engine, whereby the following operations are performed: calculation (NOx req) of a required amount of nitrogen oxides in the exhaust gases entering said converter;
adjustment (parameter correction) of the injection pressure or advance or EGR rate, on the basis of said requirement. According to the invention it is possible to increase the percentage of saturation of the catalyst with ammonia. |
