Abstract: A method for controlling a common-rail fuel injection system, which avoids the adverse effect of the pilot injection on the main injection while driving an engine and maximizes the cleaning up of the exhaust gas by the pilot injection or the like, is provided. In the common-rail fuel injection system performing a multistage injection, a pilot injection timing θp at a crankshaft angle and a main injection timing θm at the crankshaft angle base are controlled by a ECU. The ECU calculates a pilot injection interval Tpin at a time base and adjusts the main injection timing θm when the pilot injection interval Tpin is less than the predefined threshold (1 (ms) in the present embodiment).
