To provide a method for controlling a model engine, which can secure stability of operation by sufficiently throttling fuel at the time of low speed rotation.
Injection time generating means 60 generates fuel injection time according to a fuel amount per one cycle required for the driving of an engine. Intermittent injection judging means 61 judges whether or not the injection time is less than the minimum injection time which can be controlled in a fuel injection device 50. When judged that it is less than it, intermittent injection data selecting means 62 selects intermittent injection data corresponding to the injection time from intermittent injection data table 65 that equivalence between of injection time and intermittent injection data is set. Fuel is intermittently ejected to the fuel injection device 50 within injection time which can be controlled, based on the selected intermittent injection data and a timing signal from injection timing generating means 66. Stability at the time of low speed rotation is improved. Fuel can be sufficiently throttled at a low speed, therefore fuel may not be excessive and response to sudden acceleration is improved.
