A method for automatically controlling a stationary gas engine, where an engine speed control deviation is computed from a set engine speed (nSL) and an actual engine speed (nIST), and a set torque is determined as a correcting variable from the speed control deviation by a speed controller, where a set volume flow is determined as a function of the set torque to establish a mixture throttle angle (DKW1, DKW2) and a gas throttle angle, and where the set volume flow is varied to adjust the gas throttle angle by a correction factor.
