ABSTRACT:
In a method for operating an internal combustion engine (10), the fuel is supplied via at least one injection valve (32). The injected fuel quantity is influenced by the injection duration (ti). To reduce costs for the design and acquisition of the injection valve (32), it is proposed to detect as to whether a requested injection duration (ti) of the injection valve (32) is greater than a maximum possible injection duration (timxth). In this case, an intervention (64) takes place with which a desired mixture composition (rlmaxti) is produced.
