Abstract

Disclosed is a jolt damping circuit for use in fuel metering systems of an internal combustion engine having self-ignition. The jolt damping circuit includes a guide regulator, a device for generating a jolt disturbance signal in dependency on the rotary speed of the engine, and means for combining the output signal from the guide generator and from the jolt disturbance signal generator to produce a desired value setting signal applicable to regulating means for the setting member of a fuel injection pump. The jolt damping circuit is directly connectable into a standard fuel metering system of a motor vehicle.
