Patent number: 9273620Abstract: The invention relates to a method for regulating a gas engine (1) having a generator (5), 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 (pRRA, pRRB) of a fuel-air mixture in the receiver pipe (12, 13) above the inlet valves of the gas engine (1). 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.Type: GrantFiled: June 16, 2010Date of Patent: March 1, 2016Assignee: MTU FRIEDRICHSHAFEN GMBHInventor: Ludwig Kläser-Jenewein

Patent number: 9051888Abstract: 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.Type: GrantFiled: January 30, 2009Date of Patent: June 9, 2015Assignee: MTU FRIEDRICHSHAFEN GMBHInventors: Peer Smuda, Michael Prothmann, Ludwig Klaser-Jenewein
