摘要： Methods and systems are provided for cooling a high pressure fuel pump. One method includes, when a spill valve is in a pass-through state, circulating fuel from a compression chamber of the high pressure fuel pump to a step room of the high pressure fuel pump. The fuel circulation through the step room may provide for a reduction in fuel temperature in the step room, and thus, the high pressure fuel pump.

摘要： When a plunger of a high pressure pump is rising, a high pressure pump controller closes a regulator valve by energizing a solenoid of an electromagnetic actuator of the high pressure pump to discharge fuel into a delivery pipe. Further, this fuel discharge energization is stopped before the plunger reaches top dead center at a pump TDC timing. Further, a fuel pressure of the delivery pipe is detected at the pump TDC timing, and based on that detected value, a time Td from the pump TDC timing until a valve opening timing of the regulator valve is estimated. Once the estimated time Td elapses from the pump TDC timing, the solenoid is reenergized to removed a movement speed of a movable portion in a direction that pushes the regulator valve in an opening direction.

摘要： A fuel pump draws pumps fuel from a fuel tank to a pressurizing chamber during a suction stroke, and pressurizes and sends fuel in the pressurizing chamber to a delivery pipe. A electromagnetic valve is actuated by electricity from a battery to electively connects and disconnects the fuel tank with the pressurizing chamber. An ECU determines opening and closing timing of the electromagnetic valve based on the rotation al phase of an engine. When the rotational phase of the engine is not identified, the ECU executes a duty control to cyclically repeat supplying and stopping of current to the electromagnetic valve. The ECU extends a current supplying period in each cycle of the duty control as the voltage of the power supply is lowered. As a result, the electromagnetic valve is reliably closed particularly at each pressurizing stroke, which improves the pressure increasing efficiency of fuel supplied to a fuel injection system.

摘要： A unit fuel injector adapted to receive fuel from a fuel supply at relatively low pressure and adapted to inject fuel at relatively high pressure into the combustion chamber of an internal combustion engine is provided, comprising an injector body having a first internal bore and an injector orifice and a plunger mounted for reciprocating movement within the first internal bore to define a variable volume fuel pressurization chamber including a cam actuated upper plunger portion and a lower plunger portion mounted in the first internal bore between the variable volume fuel pressurization chamber and the upper plunger portion. While the upper plunger portion is in its retracted position, low pressure fuel from the fuel supply is supplied to the variable volume fuel pressurization chamber. A spring is positioned within the first internal bore to bias the upper and lower plunger portions apart to thereby allow for variation of the volume of fuel which flows into the variable volume fuel pressurization chamber during each cycle of injection operation in dependence on the pressure of the fuel from the fuel supply. A valve assembly including a valve element mounted for reciprocating movement within a second internal bore controls the flow of fuel from the variable volume fuel pressurization chamber to the injector orifice. The valve assembly allows fuel to be discharged through the injector orifice only during the time when the upper plunger portion is in its fully advanced position so that injection pressure is independent of the velocity at which the upper plunger portion moves between its retracted and advanced position.

摘要： An injector apparatus (310) for injecting fluid under pressure into an associated chamber (332) is provided. The injector apparatus (310) includes a first piston (314) defining a first working area facing an associated chamber (332), a high pressure piston (318) defining a high pressure working area facing a high pressure chamber (319), and a control piston (317) defining a control piston working area facing a control chamber (315). The first piston (314) is moveable with a body of the injector apparatus (310) to compress fluid in the high pressure chamber (319) using the high pressure piston (318), while movement of the first piston (314) is selectively controllable by controlling the fluid in the control chamber (315). The first working area is larger than the control piston working area and the control piston (317) working area is larger than the high pressure working area.
