ABSTRACT:
The invention is an electronic fuel control system for an internal combustion engine having a first capacitance which is charged to a value indicative of the engine's speed during a first rotational interval of the engine. At the end of the rotational interval, a potential indicative of the charge on the first capacitance is transferred to a second capacitance which is further charged at a predetermined rate during a second rotational interval. A comparator compares the value of the potential on the second capacitance with a signal indicative of the engine's load. The comparator generates a pulse width signal indicative of the engine's fuel requirements during the interval the potential on the second capacitance is less than the value of the load signal.
