ABSTRACT:
A method for the regulation of the mixture composition in a mixture-compressing internal combustion engine with an electronically controlled fuel injection system. In order to be able to dispense with a lambda probe, the mixture is initially enriched or leaned for each cylinder unit directly after the start of the internal combustion engine, the change between two successive firings of the energy pulse introduced into the crankshaft by an ignition is continuously determined thereafter and the mixture is enriched in the case that the amount of the respectively determined energy pulse change lies above a predetermined shifting-comparison value dependent on operating parameters, and otherwise is leaned down.
