ABSTRACT:
Controlling means of a fuel injection system regulates an energization amount of an electric motor in accordance with a sensing signal outputted from common rail pressure sensing means. Thus, the controlling means controls a fuel supply quantity of a low-pressure pump. Thus, power consumption of the electric motor driving the low-pressure pump can be regulated in accordance with a pressure-feeding quantity of a high-pressure pump. As a result, the power consumption of the electric motor can be reduced and wasteful fuel supply of the low-pressure pump can be reduced.
