Abstract
Disclosed is a system for maintaining the desired idling speed of an internal combustion engine. In its simplest form the system utilizes a speed biasing mechanism to regulate a source of fluid pressure supplied to a fluid pressure regulator to provide a first fluid pressure control signal therefrom that is proportional to changes in the rotational speed of the engine and is utilized to move a force member of an actuator device in such a manner as to maintain the engine idling speed. Alternative embodiments include combining the first fluid pressure signal in an integrator in the manner described with one or more additional fluid pressure signals derived from changes in other engine operating conditions to provide a control signal therefrom that is able to regulate a source of fluid pressure supplied to a regulator to provide the fluid pressure control signal for maintaining the engine idling speed.
