Method for operating a gas internal combustion engine (100), having - a gas mixer (40), an intake section (30) and - an engine (10) with a number of cylinders, wherein in the method - a fuel mixture comprising a charging mixture is fed to the engine (10), and the engine (10) is operated in the gas mode with gas as the fuel in the charging mixture, wherein - by means of an input mixture portion, assigned to at least one earlier mixture state, of a gas/air mixture, an output mixture portion, assigned to a later mixture state, of the gas/air mixture is determined, and wherein the determination is carried out by means of an intake section model which serves as a basis of a computing model for the intake section (30). The invention provides that - the output mixture portion of the gas/air mixture is determined at an engine feed, - the input mixture portion of the output mixture portion is determined over a number of intermediate states of the mixture portion in a number of assigned volumes of the intake section (30), wherein - the intake mixture portion of a gas/air mixture is determined at the gas mixer (40), and an air stream and/or gas stream is set at the gas mixer (40) in accordance with the input mixture portion. |
