PROBLEM TO BE SOLVED: To provide an internal combustion engine operating method and device comprising supplying fuel through at least one injection valve, the amount of the fuel to be injected being affected by an injection period, wherein an internal combustion engine with the simply designed and relatively inexpensive injection valve is positively operated. SOLUTION: The operating method for the internal combustion engine 10 comprises supplying the fuel through at least one injection valve 32. The amount of the fuel to be injected is affected by the injection period ti. A time when the injection period ti required for the injection valve 32 is longer than the maximum possible injection period timxth is measured to decrease the cost of the injection valve. 32 to be designed and procured. In such a time, intervention 64 is carried out to generate a target mixture composition.
