摘要： The present invention relates to a method and an apparatus for controlling a high-pressure fuel supply pump configured to supply pressurized fuel to an internal combustion engine, with a solenoid-actuated intake valve being configured to be biased into a first direction towards a first stop position of the intake valve by means of a biasing force and being configured to be displaced against the biasing force into a second direction opposite to the first direction towards a second stop position of the intake valve by means of magnetic force and to be kept at the second stop position by means of magnetic force. The method includes applying control current to the solenoid-actuated intake valve for displacing the intake valve into the second direction to the second stop position and for keeping the intake valve at the second stop position during a first time period by means of magnetic force.

摘要： The present invention relates to a control apparatus 700 for controlling a high-pressure fuel supply pump 100, a computer program product comprising computer program code means configured to adapt a control apparatus 700 for controlling a high-pressure fuel supply pump 100, and a method for controlling a high-pressure fuel supply pump 100 configured to supply pressurized fuel to an internal combustion engine. The high-pressure fuel supply pump 100 comprises a normally-closed type solenoid actuated intake valve 110 configured to be opened or kept open by magnetic force. A control current IC of the solenoid actuated intake valve 110 is controlled for opening the solenoid actuated intake valve 110 by applying a control voltage VC to the solenoid actuated intake valve 110. Controlling a control current IC of the solenoid actuated intake valve 110 comprises increasing the control current IC to a first control current value IC1 for energizing the solenoid actuated intake valve 110. Controlling a control current IC of the solenoid actuated intake valve 110 for opening the solenoid actuated intake valve 110 according to the present invention further comprises reducing the control current IC from the first control current value IC1 to a second control current value IC2 being smaller than the first control current value IC1.

摘要： The present invention relates to a high-pressure fuel supply pump comprising a compression chamber, a plunger reciprocating in the compression chamber for pressurizing fuel in the compression chamber, a discharge valve for discharging pressurized fuel from the compression chamber to a high-pressure fuel passage of a high-pressure fuel supply system for supplying high-pressure fuel to an internal combustion engine, and a first solenoid actuated valve for connecting and disconnecting a first low-pressure fuel passage and the compression chamber, wherein the first solenoid actuated valve is biased by a first biasing member in a closing direction of the first solenoid actuated valve, and the first solenoid actuated valve is opened or kept open against the biasing force of the first biasing member, when the first solenoid actuated valve is energized. The high pressure fuel supply pump further comprises a second solenoid actuated valve for connecting and disconnecting a second low-pressure fuel passage and the compression chamber.
