Method of operating a combustion engine

Torna indietro

Abstract

A method of operating a combustion engine comprises injecting fuel with the injection valve (17) into the combustion chamber according to an injection signal and measuring a pressure signal in the combustion chamber of the indicated cylinder (10) with the pressure sensor (18), determining an actual operating parameter for the indicated cylinder (10) depending on the pressure signal, determining a difference between the actual operating parameter and a corresponding nominal operating parameter, adapting the injection signal for the indicated cylinder (10) depending on the difference, determining a desired temporal course of the crank angle for the indicated cylinder (10) based on the adapted injection signal, determining an actual temporal course of the crank angle for a non-indicated cylinder (9) based on a non-adapted injection signal, determining a difference between the actual course and the desired course, and adapting the injection signal of the non-indicated cylinder (9) depending on the difference.
