  • Method of evaluating a soot quantity accumulated in a selective catalytic reduction washcoated particulate filter (SDPF)
    Patent number: 9970344
    Abstract: A method is disclosed for evaluating a soot quantity accumulated in a Selective Catalytic Reduction wash-coated particulate filter of an internal combustion engine. The internal combustion engine is equipped with an exhaust gas aftertreatment system including an urea injector. Using a map correlating a urea quantity value, a NOx quantity value, a temperature value and a mass flow value to a correction value of a soot quantity is used to correct an estimated value of the soot quantity in order to obtain an evaluated value of the soot quantity.
