Patent ID: 7392793

Claim:
A fuel injection controller applied to a fuel injection device of an internal combustion engine having a pressure accumulation chamber that accumulates fuel in a high-pressure state and that supplies the fuel to injectors, a fuel pump that has multiple plunges constituting pressure-feeding systems respectively and that pressure-feeds the fuel to the pressure accumulation chamber through reciprocating motion of the plungers, and a sensor that senses the fuel pressure in the pressure accumulation chamber, the fuel injection controller comprising: a control device that controls the sensed fuel pressure to target fuel pressure by operating the fuel pump; and an increasing device that increases a pressure-feeding amount of a part of the pressure-feeding systems that does not correspond to an abnormality by compulsorily changing an operation amount of the fuel pump, which is decided by the control device, based on information about the abnormality in the other part of the pressure-feeding systems.
