ABSTRACT:
A process for determining at least one fuel-injection-related parameter for an internal-combustion engine with a common-rail fuel injection system individually for each engine combustion chamber and each injection operation is provided. The pressure in the distributor pressure space, which is assigned jointly to the engine combustion chambers, of the common-rail fuel injection system is detected for a respective fuel injection operation for a respective combustion chamber in its signal course via a pressure sensor of the distributor pressure space. From the detected pressure course, a pertaining pressure course pattern is obtained from which the at least one fuel-injection-related parameter is determined individually for each combustion space and each injection operation.
