摘要： The present invention relates to a fuel injection arrangement for a diesel type engine configured to use carbonaceous aqueous slurry fuels. The fuel injection arrangement includes an injector nozzle for injecting fuel into a combustion chamber; a pump chamber housing a fuel pumping element for generating a pressurised fuel flow to the injector nozzle along an injection path between the pumping element and the injector nozzle; and a check valve connected to a fuel supply for regulating and supplying fuel to the injection path via a check valve outlet. A region immediately downstream of the check valve outlet defines an outlet region and the check valve is arranged to expose the outlet region to the pressurised fuel flow to facilitate flushing of the outlet region during fuel flow between the pumping element and the injector nozzle.

摘要： A fuel supply system includes a fuel pump having an inlet configured to pick up fuel and an outlet configured to discharge fuel. A pressure vessel is in fluid communication with the outlet of the fuel pump such that fuel is directed from the fuel pump into the pressure vessel, the pressure vessel having an outlet port. A pressure regulation valve subassembly is detachably coupled with the outlet port via a male-female interface that positively locks against axial separation upon axial coupling in a first orientation and relative rotation of less than 360 degrees to a second orientation. A reservoir defines an internal space at least partially receiving the fuel pump, the pressure vessel, and the pressure regulation valve subassembly. The reservoir includes an interior wall that obstructs rotation of the pressure regulation valve subassembly from the second orientation to the first orientation.

摘要： A system for controlling pressure of fuel supplied to an engine is disclosed. The system includes a pressure sensor to generate signals indicative of pressure of fuel at an outlet of a pressure regulator. The system includes a stepper motor coupled to a gear drive. The system includes a controller, in electric communication with the pressure sensor and the stepper motor, monitors the pressure of the fuel and determines an average pressure of the fuel at the outlet of the pressure regulator for a predefined cycle. The controller compares the determined average pressure with a threshold pressure and generates an output signal when the determined average pressure is beyond the threshold pressure. The controller further communicates the output signal with the stepper motor to preload the pressure regulator and controls the pressure of the fuel at the outlet of the pressure regulator.
