ABSTRACT:
A limiting speed mechanical engine governor has a speed responsive fuel decreasing mechanism opposed by a high speed spring, the effective force of which controls the maximum governed speed of the engine. A speed adjuster, such as an air actuated piston, is arranged to act against the operative end of the high speed spring to controllably reduce its preset speed setting force and thus provide for controlled reduction of the maximum governed speed of the engine. A control system is disclosed for use on a vehicle, such as a diesel engine powered truck, to permit using the variable maximum speed capability of the governor as a road speed control for the vehicle or to provide a reduced controlled engine speed for operating engine driven accessories when the vehicle is stationary.
