A device for preventing unbalance between respective engine cylinders of a motor vehicle adapted to adjustingly control the fuel amount supplied to each cylinder of the engine, and the injection time, according to engine revolution changes to thereby reduce engine noise caused by deviation of engine revolutions. The device includes: a unit for detecting engine speed and fuel amount relative to each cylinder when fuel is supplied to each cylinder of the engine; a unit for respectively adjusting injection pulse width responsive to the engine speed and fuel amount detected by the detecting unit; and a unit for establishing a driving time of injection to each cylinder for the engine speed to be close to a reference speed for the injection pulse widths of the respective cylinders.
