EXCESS FUEL STARTING DEVICE FOR FUEL INJECTION ENGINES ABSTRACT OF THE DISCLOSURE An excess fuel starting device for a fuel injection engine having a full load stop coacting with the engine throttle link- age to limit the fuel input from the fuel injection pump to the engine. A hydraulic actuator positions the full load stop in either a normal run position or an excess fuel position. The actuator includes a cylinder containing an excess fuel piston operatively connected to the full load stop and spring biased toward an excess fuel position. A coaxial bore within the ex- cess fuel piston contains a free piston slidable therewithin. Fluid conduit means is provided for delivering a fluid pressurized during engine operation to actuate only the smaller free piston when the actuator is in the excess fuel position. Then the ex- cess fuel piston has been moved by the action of the free piston to the normal run position, the fluid conduit means delivers the pressurized fluid to provide a holding force against the larger excess fuel piston. The differential in the actuating pressure versus the holding pressure of the device may be varied to suit the installation requirements by the choice of the re- lative diameters of the excess fuel and inner pistons. - 1 -
