ABSTRACT:
Embodiments of engine speed control and methods of maintaining engine speed control and fuel injection so as to minimize hunting and improve exhaust emission control, particularly at low speeds. This is achieved by setting a fixed amount of fuel supplied to the engine per cycle, per cylinder when the engine speed is below a predetermined speed or a speed below a predetermined speed is called for. Engine speed control is maintained under the constant fuel position by controlling the spark advance in one embodiment. A manual spark advance and automatic spark advance are depicted.
