Abstract

A method for operating an internal combustion engine having two or more cylinders to which fuel can be supplied via an injection valve, it being possible to carry out a measurement injection for a cylinder in order to determine and/or adapt a characteristic quantity of the injection valve, and all the cylinders being ignited in the course of an ignition cycle. To improve the operating characteristics, a measurement injection is carried out for those cylinders that are contained in a specifiable selected set selected from all the cylinders.
