Fuel injection pump

A fuel injection pump provided in a diesel engine, comprising:

• an electromagnetic spill valve configured to adjust a fuel injection amount by releasing pressurized fuel with opening/closing of a valve body;
• and
• a control device configured to form a current waveform of drive current of the electromagnetic spill valve,
• wherein, during a warm state, the control device detects a time of opening the valve body of the electromagnetic spill valve as a first timing, detects a value of flowing current at the time of opening the valve body as a first current value, detects a time of closing the valve body of the electromagnetic spill valve as a second timing, detects a value of flowing current at the time of closing the valve body as a second current value;
• after closing the valve body, shapes a current waveform of the drive current so that a value of current in the electromagnetic spill valve returns from the second current value to the first current value, within a period equivalent to a time elapsed from the first timing to the second timing;
• and applies the drive current with the shaped current waveform to the electromagnetic spill valve, and wherein, during a cold state, the control device applies only drive current with a pre-set current waveform to the electromagnetic spill valve.
