Abstract
A fuel pump manifold pressure control system may be effective to provide a compact and more effective fuel pump mechanism for compression ignition engines, such as diesel and some natural gas engines. The fuel pump manifold pressure control system includes a fuel pump manifold, at least one fuel injection accumulator adapted for supplying pressurized fuel to at least one fuel injector, a pressure control valve, a pressure sensor, and a pressure relief valve, all contained within a compact fuel pump housing. The pressure control valve and pressure sensor are each adapted for signal communication with electronic controller, and for fuel communication with the fuel pump manifold. The pressure relief valve is adapted for fuel communication with the fuel pump manifold. Each of the control valve, sensor, and relief valve are fixedly mounted to and internally contained within the housing.
