Abstract (en)

[origin: DE10114252A1] The method involves controlling the start and end of the injection process by opening and closing fuel injectors. During injection a definite reduction in the fuel pressure occurring in the injectors occurs so that the increased pressure caused by closing the injection valve at the end of the injection process does not exceed a defined level. An Independent claim is also included for a fuel injection system for an internal combustion engine, especially a diesel engine.
