Abstract

In a method or a device for forming an electric control signal for an injection impulse of a position-controlled fuel injector, particularly of a common-rail or pump-nozzle injection system, the course of the electric control signal can be selected freely in regard to the pulse edges (injection rate changes Q), the holding period (Δt) and the injection rate (Q). This offers the advantage that the combustion process can be better optimized with respect to low emissions, low consumption and for meeting tightened legal regulations.
