Abstract
A method for operating an internal combustion engine is disclosed, in which method test injections are carried out in order to adapt, during the operation of the internal combustion engine, the injection parameters used for the control of the injection processes. For this purpose, during the test injections, an electric machine which is coupled to the internal combustion engine generates negative torque impulses in a manner synchronized with the positive torque impulses generated by the test injections, which negative torque impulses counteract the torque impulses generated by the test injections. In this way, rotational speed oscillations generated by the test injections are eliminated. Also described is an internal combustion engine of said type.
