Abstract

The invention relates to a method and device for regulating internal combustion engines to take into account the air humidity, especially in automobiles, by means of at least one temperature sensor (1) and a sensor (2) for directly or indirectly detecting the relative air humidity phi . According to the invention, a correction factor (a) is determined. The quantity of fuel supplied to the internal combustion engine is then adjusted according to said correction factor. The total pressure p of the humid air is optionally taken as constant or detected additionally.
