METHODS OF STARTING A HYDRAULICALLY-ACTUATED ELECTRONICALLY-CONTROLLED FUEL INJECTION SYSTEM |
摘要 |
Methods of starting a hydraulically-actuated electronically-controlled fuel injection system are disclosed. One method comprises the steps of pressurizing actuating fluid used to actuate a unit injector and actuating an electrical actuator assembly of the unit injector to cause fuel injection only when the pressure of the actuating fluid is at least equal to a selected minimum level. This method of the present invention ensures that the unit injector does not diminish the pressure of the actuating fluid until the pressure has reached a selected minimum level required to effect fuel injection. This method allows the pumping capacity of the high pressure actuating fluid pump to be minimized while ensuring quick starting of an engine by the fuel system. |
