  • Method for the drift compensation of an injector for the direct fuel injection in a cylinder of an internal combustion engine as well as a device
    Patent number: 7069138
    Abstract: In the case of direct injection internal combustion engines, the problem occurs that especially the injection of a minimum amount of fuel depends in particular on different operating parameters such as the speed, the start of the injection or the rail pressure. Therefore, a method or a device is suggested in which a control unit (10) subdivides the complete range of values of at least one operating parameter into discrete sections. Subsequently, for each section, at least one operating point is specified for which a corresponding correction value depending on the operating parameter is determined and obtained. The correction value is then stored together with its corresponding operating point. This has the advantage that the correction value can be determined more accurately because interpolation can for example also be performed between two operating points.
