Abstract

In a device and a process for controlling an injection actuator of a self-igniting internal combustion engine, on the basis of the operating conditions, a fuel amount signal (QKO) can be given, which depends at least on the driver's command. Under certain operating conditions, regardless of the driver's command, a minimum amount is injected to actuate the injection actuator.
