METHOD FOR OPERATING AN INTERNAL POWER ENGINE

Abstract

A method for operating an internal combustion engine during a defined cycle, wherein the raw engine emissions of the internal combustion engine are adjustable via at least one emission control parameter, and wherein the cycle is assigned at least one observation window (F1, F2, F3) with a start (A1, A2, A3) and end point (B1, B2, B3), characterized in that within a first observation window (F1) of the cycle with a first start point (A1) and a first end point (B1), at the time of the first end point (B1), at least one partial observation window (F2) is defined with a partial window start point (A2) located before the first end point (B1) and a partial window end point (B2) coinciding with the first end point (A2), wherein, based on an emission quantity (E) of the partial observation window (F2) before reaching the second end point (B3) of a second observation window (F3), the second start point (A3) of which is located before the first end point (B1), lies,a predictive and quantitative estimation of at least one considered emission quantity (E) is carried out for the second observation window (F3) and the estimated emission quantity for the second observation window (F3) is compared with a defined maximum emission quantity, and wherein, upon reaching or exceeding the maximum emission quantity, at least one emission control parameter of the internal combustion engine is adaptively changed so that the quantity of the considered emission (E) is reduced.
