Disclosed a regulating device for a fuel volume adjuster of a self-igniting internal combustion engine. In order to damp jerking movements resulting at different power transmissions, a signal corresponding to the actual rotary speed of the engine is fed back into an electronic regulating circuit. Preferably, the feedback path includes a phase shifter. It is essential that the regulating action of the rotary speed be not delayed by the phase turning shifter. For this purpose, the electronic regulating circuit includes a PI stage and the fed back signal is applied to the regulating circuit only after its I-constituent has become effective.
A regulating device for an adjuster of a self-igniting internal combustion engine including sensors for producing at least one signal corresponding to actual rotary speed of the engine, comprising control means for generating at least one signal corresponding to a desired rotary speed of the engine, means for comparing the desired and actual rotary speed signals, and an electronic regulating circuit connected between the comparing means and a fuel dose adjuster, said regulating circuit including a phase rotating member and a feedback path for the actual rotary speed signal, said feedback path being coupled to said regulating circuit after said phase rotating member.
