Fuel injection controller of internal combustion engine

摘要

The pressure within the common-rail 3 is reduced when the engine is stopped without an operation of the automatic engine stopping and restarting device for automatically stopping and restarting the engine to improve fuel consumption. A reducing amount of the pressure within the common-rail 3 when the engine is stopped with an operation of the automatic engine stopping and restarting device is made smaller than that when the engine is stopped without an operation of the automatic engine stopping and restarting device.
