A method and apparatus for controlling an engine for models include setting an injection period for fuel in accordance with an amount of fuel per cycle required for operating of the engine; judging whether the injection period is below a minimum injection period controllable in a fuel injection apparatus of the engine, selecting an intermittent injection data corresponding to the injection period when the injection period is below the minimum injection period; and intermittently injecting fuel into the fuel injection apparatus for a controllable injection period at an injection timing based on the selected intermittent injection data.
