Abstract
An i.c. engine fuel system uses a conventional carburettor modified by the addition of an air pressure control to the float chamber thereof. The air pressure control includes a bank of valves connected in parallel to exhaust a chamber connected by an orifice to the engine intake manifold. The chamber is connected to the float chamber and the valves are controlled by the individual bits of a digital output signal produced by a digital read only memory addressed by digital signals corresponding to two engine parameters such as engine speed and throttle angle.
