ABSTRACT:
A distributor type fuel injection pump has an accumulator. When an internal combustion engine is in low-speed rotation or in low-load operation, the accumulator accumulates part of the fuel pressurized within a fuel compression chamber, thereby lowering the fuel injection rate. Also, the fuel injection pump is provided with compensator which operates simultaneously with the accumulator. While the injection rate is lowered by operation of the accumulator, the compensator extends the injection period to compensate for the reduction of injection quantity attributed to reduction of the injection rate.
