Control system and method for adjusting a controller, in particular a retrofittable one, with which an internal-combustion engine operated with liquid fuel is operated with gaseous fuel after change-over

摘要

Control device used in an internal combustion engine for controlling at least one signal for at least one fuel injector operated with liquid or gaseous fuel comprises at least one processor (54) processing the input signals for gas operation and at least one switching unit (62) coupled to the processor and processing at least one injection signal from an engine control device for liquid fuel and feeding it as an injection signal for liquid or gaseous fuel to at least one fuel injector. An Independent claim is also included for a process for setting the above control device. Preferred Features: A signal processor (66) arranged upstream of the switching unit and coupled to or integrated in the processor processes the input signals determined by the processor and converts the original signals and feeds them as injection signals for gaseous fuel to a fuel injector for gaseous fuel.
