Abstract
A method provides for detecting deviations of injection quantities for injections into internal combustion engines, as carried out for example by common-rail systems. At least one deviation of at least one injection quantity is detected by determining at least one deviation, from a predefined value in each case, of at least one value of at least one variable controlling an actuator of the injector and/or indicating at least one state of the actuator.

A method for detecting injection quantity deviations in injectors, comprising
- detecting at least one deviation of at least one injection quantity by determining at least one deviation, from a predefined value in each case, of at least one value of at least one variable, wherein the at least one variable at least one of controls an actuator of the injector and indicates at least one state of the actuator.
A method for correcting injection quantities, wherein comprising
- detecting a deviation in at least one injection quantity by determining at least one deviation, from a predefined value in each case, of at least one value of at least one variable, wherein the at least one variable at least one of controls an actuator of the injector and indicates at least one state of the actuator;
- and
- correcting the injection quantity by correcting at least one value controlling the actuator such that the at least one deviation of a value is reduced, minimized or eliminated.
An injection system comprising at least one injector which has at least one actuator, wherein the injection system is operable to at least one of detect and correct a deviation of an injection quantity injected by the at least one injector by by determining at least one deviation, from a predefined value in each case, of at least one value of at least one variable, wherein the at least one variable at least one of controls an actuator of the injector and indicates at least one state of the actuator.
