Abstract
A gas internal combustion engine, having a gas mixer, an intake section and an engine to which a fuel mixture having a charging mixture is fed. The engine is operated in the gas mode with gas as the fuel in the charging mixture. By an input mixture portion, from an earlier mixture state, of a gas/air mixture, an output mixture portion, from a later mixture state, of the gas/air mixture is determined by an intake section model. The output mixture portion is determined at an engine feed, the input mixture portion is determined over a number of intermediate states of the mixture portion in a number of assigned volumes of the intake section. The intake mixture portion of a gas/air mixture is determined at the gas mixer, and an air stream and/or gas stream is set at the gas mixer in accordance with the input mixture portion.
