ABSTRACT:
The invention pertains to apparatus for controlling the quantity of fuel delivery to an engine and engine timing. Several problems with prior apparatus include their high cost and inability to be easily programmed for control purposes, together with their use of complicated electrical controls to meet reliability standards. The inventive solution includes a control rod (16) having a plurality (25,84) of control surfaces of preset shape that determine the maximum quantity of fuel delivery to the engine and engine timing. A plurality (30-36, 40,70) of hydromechanical control circuits axially and rotatably move the control rod (16) in response to engine speed and load. A plurality (18,26,28 and 90-100, 100') of devices control the maximum quantity of fuel delivery and engine timing based on the axial and rotatable positions of the rod (16). The inventive apparatus is used principally to control exhaust emissions from an engine.
