Fuel injection system for internal combustion engine has device for changing current to solenoid depending on measured battery voltage, device for correcting command signal depending on changed desired value

Fuel injection system for internal combustion engine, has injection-quantity correction unit to correct injection quantity of fuel to eliminate pressure difference in target pressure and in-pipe pressure during fuel injection

Control unit of fuel feed system has control quantity computing unit for calculating drive control quantity by characteristic deviations of fuel pump calculated by first and second computing units

Pressure accumulation type fuel injection apparatus for diesel engine has pressure reduction facilitator that lengthens opening period of injector valve by excess injection quantity so that fuel might be injected
