A fuel injection control device for an internal combustion engine

摘要

A fuel injection control device for an internal combustion engine (1) comprises a common-rail (3) for accumulating pressurized fuel, and an automatic engine stopping and restarting device for automatically stopping and restarting the engine (1), wherein the pressure within the common-rail (3) during engine stopping is changed over as the engine (1) is stopped with an operation of the automatic engine stopping and restarting device, or without, wherein the pressure within the common-rail (3) when the engine (1) is stopped with operating of the automatic engine stopping and restarting device is maintained at or reduced to a pressure higher than the pressure within the common-rail (3) allowing fuel to be injected.
