ABSTRACT:
A controller for a diesel engine fuel injection system of the type characterized by an injector for each engine cylinder driven by a variable high pressure "common rail" fluid. The controller generates and regulates the rail pressure, meters the fuel to the injectors, and times the firing of the injectors in accordance with engine requirements. The controller is characterized by a novel ring cam-driven piston pump for generating the high common rail pressure and a novel differential piston regulator for regulating the common rail pressure. The controller further includes a novel metering system for metering the discrete quantities of fuel delivered to the injectors.
