Electromagnetic fuel injector
 An electromagnetic fuel injector comprising a fixed iron core, a solenoid formed by winding a coil around the fixed iron core, a coil holder fixed to the solenoid, an injector casing surrounding the solenoid and the coil holder and formed of a material having high magnetic permeability, a movable iron core inserted between the fixed iron core and the injector casing, a compression spring normally biasing the movable iron core toward an injection nozzle of the injector, a valve body connected at its base to the movable iron core and formed with a flange at a base portion thereof, a stopper adapted to abut against the flange of the valve body and restrict a movable range, a valve housing incorporated in a front portion of the injector casing and slidably supporting the valve body, the valve housing being formed at its front end portion with a valve seat adapted to abut against the valve body, and a radiation member closely fitted on an outer periphery of the injector casing. A connection member may be provided connecting a plurality of injectors mounted on cylinders in a multi-cylinder engine for radiating heat generated in the injectors.
