the invention relates to a method for regulating a gas engine having a generator , wherein a regulator torque is calculated by means of a speed regulator from a speed regulator deviation , wherein a target volume flow is calculated at least as a function of the regulator torque , wherein a fuel volume is determined as a proportion of a fuel - air mixture as a function of the target volume flow , and wherein a target receiver pipe pressure is also calculated as a function of the target volume flow as a guide parameter for a receiver pipe pressure regulating circuit for regulating the mixture pressure of a fuel - air mixture in the receiver pipe above the inlet valves of the gas engine . the invention is characterized in that a deviation of the regulator torque from a generator torque is calculated and the target receiver pipe pressure is corrected using the deviation .
