摘要

A method for the calculation of the NO₂content at the inlet of a selective catalytic reduction—SCR—device (22) of an exhaust system (4) with: an exhaust pipe (10); a tank for a reducing agent and injection elements (18); a first sensor (20) for measuring the concentration of nitrogen oxides upstream of the SCR; and a second sensor (24) for measuring the concentration of nitrogen oxides downstream of the SCR, includes the following stages: halting the injection of reducing agent; measuring the concentration of nitrogen oxides upstream and downstream of the SCR during a period of time; calculating the amount of NO₂accumulated in the SCR during the period of time; and determining the NO₂content upstream of the SCR from the calculated amount of NO₂accumulated per unit of time.
