Patent ID: 8011350

Claim:
A high pressure fuel pump control apparatus for an internal combustion engine, comprising: a rotational position sensor that outputs a predetermined pulse signal in accordance with the rotational position of an internal combustion engine; a high pressure fuel pump that has a solenoid for opening and closing a fuel suction valve arranged between a fuel suction port and a pressure chamber, and serves to pressurize fuel supplied from said fuel suction port to said pressure chamber through said fuel suction valve and deliver it from a fuel delivery port; an accumulator that accumulates the fuel delivered from said high pressure fuel pump; a fuel pressure sensor that detects the pressure of fuel in said accumulator; and a control section that performs identification of cylinders of said internal combustion engine based on said predetermined pulse signal, and controls the energization timing of said solenoid based on a detected value of said fuel pressure; wherein when the cylinder identification of said internal combustion engine is completed, said control section controls the energization timing of said solenoid based on the rotational position of said internal combustion engine, whereby valve closing timing of said fuel suction valve is controlled to deliver, from said high pressure fuel pump, an amount of fuel necessary to make the detected value of said fuel pressure coincide with a target pressure; and said control section includes a starting time control section for continuously energizing said solenoid over a period of time from a time point at which said internal combustion engine begins to be started until a time point at which said cylinder identification is completed to make it possible to control the valve closing timing of said fuel suction valve.
