PURPOSE: A fuel injector control device having a swirl port is provided to increase combustion efficiency, and to improve output and torque of an engine by mixing air and fuel with flowing mixed air to a combustion chamber fast and forming vortex in idling or at low-speed rotation. CONSTITUTION: A fuel injection controller comprises a cylindrical swirl port(4) installed in an intake port(3) near an intake valve(2) in a throttle body(1) to form vortex with intake supplied to a combustion chamber(5); a swirl control valve(6) in the upper part of the swirl port opening and closing the intake port and adjusting the air flow passing through the swirl port; a solenoid valve operating the swirl control valve; and a control unit actuating the solenoid valve with pressure of a manifold according to signals from a distributor and an air flow meter. A cylindrical body forming the swirl port reduces resistance of intake flowing to the swirl port with a streamlined section in the inlet of the swirl port. The swirl port improves combustion efficiency by forming vortex with intake into the combustion chamber through a spiral groove.
