<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device performing variable injection quantity control by intermittently performing fuel injection during a period when fuel pressure produced with fuel injection is intensified by a pulsating change. <P>SOLUTION: A fuel injection valve 6 injects fuel supplied from a common rail 13 to the combustion chamber of an engine 1. A fuel pressure sensor 37 detects fuel pressure to the fuel injection valve 6 and outputs a fuel pressure signal. An ECU 2 controls the fuel injection valve 6 based on the detected fuel pressure signal, learns time to indicate a peak value of fuel pressure fluctuated when injecting fuel, and controls injection quantity by correcting the subsequent injection timing in time for the time to indicate the peak value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
