    摘要: A method of operating a combustion engine is described. The combustion engine comprises a cylinder, a piston, an injection valve and a pressure sensor, wherein the cylinder and the piston delimit a combustion chamber. The method comprises injecting fuel with the injection valve into the combustion chamber according to an energizing time (ET), measuring a pressure signal in the combustion chamber with the pressure sensor, determining a first course (51) of a value (Vb1) of an integrated heat release plateau depending on the pressure signal for several energizing times (ET), determining a second course (52) of the value (Vb1) for several energizing times (ET) after a given running time of the combustion engine, evaluating a first and a second offset point (OP1, OP2) of the first and the second course (51, 52), and evaluating a corrected energizing time (ETcorr) depending on the first and the second offset point (OP1, OP2).
