Abstract
A fuel feed device for an engine capable of electronically controlling the fuel feed rate corresponding to the suction air flow rate in the intake passage, comprising an air flow rate detecting device for generating electric signals of frequencies proportional to suction air rate, a plurality of electromagnetic valves with a different fuel passage section from one another disposed at a suitable position in the intake passage and adapted so as to permit supplying through a fuel pressure regulator the fuel of a fixed pressure differential with the suction pressure near a fuel outlet, and an electric control means for driving the electromagnetic valves selectively in synchronism with or to follow the frequency of the electric signals or a divided frequency thereof in accordance with the engine operating condition. Thus an accurate and highly reliable fuel supply is achieved over a wide range of engine operating condition from idling to maximum speed operation.
