Method and system for regulating the composition of an air/fuel stream supplied to an internal-combustion engine, comprise determining the mixture flow of the stream, the energy concentration of the air/fuel stream being measured and, from this, the desired mixture flow being determined and compared with the prevailing mixture flow and, if appropriate, correction of the air/fuel composition being carried out. Measuring the mixture strength may consist in the catalytic combustion of part of the mixture and determining the resulting temperature increase. The mixture flow can be determining by measuring the rotational speed of the engine and its inlet pressure and inlet temperature. Instead of comparing the determined and desired mixture flow, it is also possible to compare the prevailing and desired energy concentration and then to carry out a correction.
