Fuel delivery systems for combustion ignition engines and more particularly to devices for limiting exhaust smoke and/ or the rise in engine torque. When a compression ignition engine is operating at full speed and a load is applied to the engine, the engine speed decreases until a lug condition results. As the engine speed decreases, a greater volume of fuel is delivered to the combustion chambers resulting in an inherent increase in the output torque of the engine and in the production of smoke, the rotation sensitive pressure regulator (7) described herein solves these problems by using a movable spool valve (21a). Stability of the regulator (7) is also achieved by using a spring (40) that adjusts the static force applied to the spool valve (21a) and a nondeformable actuator member (19). |
