Abstract
A method for cylinder-specific adjustment of the injection quantity in internal combustion engines is provided, as well as an internal combustion engine with which the method may be implemented. The injection quantity per cylinder selected by the engine management is changed in a controlled manner following an orthogonal experimental plan. The effect of this change on the excess-air factor 'lambda' is analyzed, allowing the formulation of a regression polynomial to determine necessary corrections of the injection quantity, which injection quantity is adjustable individually for each cylinder with a view to optimum combustion.
