Abstract
The invention relates to a system for controlling an internal combustion engine (100), in particular a self-igniting internal combustion engine. A signal (U) for triggering a performance-determining final controlling element (105) is stored in a characteristics map (110) for each of a corresponding fuel quantity (QK) to be injected into the engine. The signal values stored in the characteristics map (110) are then corrected in dependence upon a predetermined relationship of a signal corresponding to the value for the fuel quantity (QK) to be injected and a signal corresponding to the value for the actually injected fuel quantity (QKI).
Claims10
A system for controlling an internal combustion engine, in particular a self-igniting internal combustion engine, comprising:
- a performance-determining controlling element;
- means for generating signals (U) for triggering the performance-determining controlling element;
- a characteristic map for storing a value of a signal (U) for each of a corresponding fuel quantity (QK) to be injected into the engine, the stored values of the signal (U) being corrected based on a predetermined relationship between a value for the fuel quantity (QK) to be injected and a value for an actually injected fuel quantity (QKI);
- and
- a first sensor adapted to measure a first engine parameter, the parameter corresponding to an air ratio lambda value (.lambda.), with the actual injected fuel quantity (QKI) being determined as a function of an intake-air quantity (QL) and the air ratio lambda value (.lambda.).
