Abstract
In effecting individual cylinder fuel injection control in an electronically controlled diesel engine, wherein rpm variations with every explosion cylinder are detected and compared with one another, and a fuel injection quantity control actuator is controlled with every cylinder so as to make the rpm variations of respective cylinders uniform, so that engine vibrations due to a dispersion in fuel injection quantity between the cylinders can be controlled, a movement value corrected driving command timing to the fuel injection quantity control actuator is determined in accordance with a difference between individual cylinder correction quantities of last time and this time and a driving command is given to the fuel injection quantity control actuator with every cylinder in accordance with the movement value corrected driving command timing.
