| description | A method and apparatus for controlling fuel injection in an internal combustion engine is disclosed which controls a fuel injection pressure and a fuel injection energizing time, by using as input parameter an estimated corrected injector fuel quantity (Qertd). In particular, an injector fuel quantity deviation ( QCB) corresponding to a current engine operating point is estimated and stored in a corresponding point of a map, representing engine operating points defined in terms of injection pressure and injector fuel quantity values. The stored injector fuel quantity deviation ( Qstored) are spread or propagated to each map point. For each engine operating point, the corrected injector fuel quantity (Qertd) is calculated by blending estimated values of the injector fuel quantity deviation ( QCB) with corresponding spread values of the stored injector fuel quantity deviation ( Qstored) and summing this result to corresponding target values of the injector fuel quantity (Qtarget). |
