A method for operating an internal combustion engine with several combustion chambers and internal combustion engine with several combustion chambers

摘要

The invention relates to a method (61) for operating an internal combustion engine (11) with several combustion chambers (15), wherein at least one combustion chamber (15) an injection valve (13) for the injection of fuel (m_f) in the combustion chamber (15) is associated, wherein for at least one combustion chamber (15) each air / fuel ratio (λ) is adjusted and / or for at least one combustion chamber (15), a space individual torque (m) is determined. In order to achieve a method (61) for operating an internal combustion engine (11) with which for individual combustion chambers (15) specific properties is detected and, if appropriate, can be compensated, whereby false adaptations are to be prevented as far as possible, it is proposed that for at least one injection valve (13), a triggering duration (t_A) of the injection valve (15) in such a manner by means of detecting or determining a valve opening duration (t) of the injection valve (15) is adapted or (a) is that tolerances of the injection valve (15) with respect to a relationship between the triggering duration (t_A) and the valve opening duration (t) can be compensated for at least substantially.
