Abstract:
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.
