Abstract: A method of proportioning fuel in an air/fuel mixture to be fed to an internal combustion engine upon starting, which method ensures reliable starting, even when fuel-injection settings which have been determined for good fuel, are used with poor fuel. As long as a test-end condition has not been satisfied, the engine's speed of rotation is checked to determine whether an increase in speed of rotation is present within a predetermined range. If not, a stored correction value for correcting the amount of fuel injected, which is determined as a function of the state of operation of the engine, is changed in such a manner so as to yield an air/fuel mixture which is ignitable in a desired manner, which mixture leads, upon combustion, to an increase in the speed of rotation within the predetermined range.
