Abstract (en)
[origin: EP1526267A2] The method involves injecting a defined amount of fuel. A correction value is determined, where the correction value is applied to a value range of an operating parameter e.g. rail pressure, of an internal combustion engine. The complete range of values of the operating parameter is subdivided into discrete sections using a control unit (10), where an operating point is specified for each section. An independent claim is also included for a device for drift compensation of an injector.
